ovirt 4.4 self-hosted deployment questions
by Michael Thomas 28 Aug '20

28 Aug '20

I have not been able to find answers to a couple of questions in the self-hosted engine documentation[1]. * When installing a new Enterprise Linux host for ovirt, what are the network requirements? Specifically, am I supposed to set up the ovirtmgmt bridge myself on new hosts, or am I supposed to let that be handled by the engine when I add the new host to the engine? * In the 'New Host' dialog on the engine management page, does the Hostname/IP that I enter have to be the host's name on the ovirtmgmt LAN? If so, then it seems to me that I need to configure the ovirtmgmt bridge myself on new hosts. * Does the engine need to be able to route outside of the cluster (eg to the WAN), or is it allowed to restrict the engine's routing to the local cluster? * In the 'New Host' dialog on the engine management page, what is the meaning of 'Choose hosted engine deployment action'? From the way it is phrased, it sounds like this will create a second engine in my cluster, which doesn't make sense. Or does this mean that the new host will be able to run the Engine VM in a HA manner? In my current test deployment I have 3 subnets in my cluster. Network WAN is the WAN. Network CLUSTER is for communication between cluster compute nodes, storage servers, and management servers. Network OVIRT is for ovirt management and VM migration between hosts. My first self-hosted engine host is connected to networks CLUSTER and OVIRT. The engine VM is only connected to network OVIRT through a bridge on the host, but has a gateway that lets it route traffic to network CLUSTER (but not network WAN). Is this an appropriate network setup for ovirt, or should there be no distinction between the CLUSTER and OVIRT networks? --Mike [1]https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_eng…

Hi Everyone, I would like to use Distrbuted Volume type but the volume type is Gray out. I can only use the replicate type. It's normal ? 3 ovirt Servers 4.4.1-2020080418 Can I configure a replicate volume for the engine domain and Distributed for the data domain? Thank you Dominique Deschênes Ingénieur chargé de projets, Responsable TI 816, boulevard Guimond, Longueuil J4G 1T5 450 670-8383 x105 450 670-2259

TroubleshootingoVirt Node deploy FQDN not reachable
by David White 27 Aug '20

27 Aug '20

In a recent thread, Roberto mentioned seeing the error message "FQDN Not Reachable" when trying to deploy oVirt Node 4.4.1, but was able to get past that error when using ovirt-node-ng-installer-4.4.2-2020080612.el8.iso. I experienced the same problems on oVirt Node install 4.4.1, so I tried the latest release of 4.4.2. When that failed, I went back and installed from the exact same image as Roberto said worked on the 4.4.2 branch: ovirt-node-ng-installer-4.4.2-2020080612.el8.iso Unfortunately, that's still not working for me - so that tells me I'm probably doing something wrong. Given the following facts: [root@dev1-centos ~]# hostname dev1-centos.office.barredowlweb.com [root@dev1-centos ~]# host dev1-centos.office.barredowlweb.com dev1-centos.office.barredowlweb.com has address 192.168.2.96 I am trying to install oVirt using the Hyperconverged Gluster Wizard for a Single Node. In the "Host1" box, I enter the full hostname: dev1-centos.office.barredowlweb.com And that's when I get the FQDN error message. Am I missing something here? Sent with ProtonMail Secure Email.

Is the Hosted Engine setup finished + Can't connect vdsm storage
by Bielej SRE 27 Aug '20

Hi, We have 6 node oVirt setup with Compatibility version 4.3 running on CentOS 7.6.1810 Recently We have found out some very interesting log entries on a few of our nodes. /var/log/ovirt-hosted-engine-ha/broker.log: MainThread::INFO::2020-08-27 12:51:50,279::storage_backends::345::ovirt_hosted_engine_ha.lib.storage_backends::(connect) Connecting the storage MainThread::INFO::2020-08-27 12:51:50,280::storage_server::349::ovirt_hosted_engine_ha.lib.storage_server.StorageServer::(connect_storage_server) Connecting storage server MainThread::warning::2020-08-27 12:51:50,284::storage_broker::97::ovirt_hosted_engine_ha.broker.storage_broker.StorageBroker::(__init__) Can't connect vdsm storage: 'NoneType' object has no attribute 'startswith' /var/log/messages Aug 27 12:52:11 ildeco25 vdsm[6909]: ERROR failed to retrieve Hosted Engine HA score '[Errno 2] No such file or directory'Is the Hosted Engine setup finished? We have inherited that setup from the previous team but I'm fairly certain the the Hosted Engine setup is finished. Also, this line is not present on all hosts.

Host has no default route
by Wesley Stewart 27 Aug '20

27 Aug '20

I am trying to add a host to a single host cluster. Everything has gone pretty well so far, except when the host gets to the end of the installation process, I see an exclamation mark indicating "Host has no default route". The installation "finishes" and the host goes into a non-responsive state. I am not really sure where to check. I get a: host *name* installation has failed. Network error during communication with host. Running 4.3.6 Thanks!

LDAP/AD issue
by kim.kargaard＠noroff.no 26 Aug '20

26 Aug '20

Hi all, We have had our ovirt instance connected to our internal AD for users to log into the VM portal for the last year, linked to studentdomene.noroff.no. This has been working without any problems. We had it set up and the DNS server had a forward record to the DC's. All good. Then, of course, the institution decided to introduce student emails and they decided to add the domain stud.noroff.no for student emails and made this the primary domain in the AD. The problem is that when this is changed, students can no longer log into the engine. I have of course changed the ldap settings and added a forward record on the DNS to the new domain. However, it seems that the domain is studentdomene.noroff.no, but with an added UPN suffix with stud.noroff.no When students try to log in, with the config changes, they get this error in the browser: server_error: An error occurred while attempting to query DNS in order to retrieve SRV records with name '_ldap._tcp.stud.noroff.no': NameNotFoundException(DNS name not found [response code 3]), ldapSDKVersion=4.0.7, revision=b28fb50058dfe2864171df2448ad2ad2b4c2ad58 Any ideas on how to solve this issue? My config looks like this: sudo cat /etc/ovirt-engine/aaa/Students.properties [sudo] password for noroffadmin: include = <ad.properties> vars.domain = studentdomene.noroff.no vars.user = CN=ovirt auth,CN=Users,DC=stud,DC=noroff,DC=no vars.password = PASSWORD pool.default.auth.simple.bindDN = ${global:vars.user} pool.default.auth.simple.password = ${global:vars.password} pool.default.serverset.type = srvrecord pool.default.serverset.srvrecord.domain = ${global:vars.domain} my forward on the DNS server looks like this: sudo cat /etc/named/named.conf.local [sudo] password for noroffadmin: zone "platform.noroff.no"{ type master; file "/etc/named/zones/db.platform.noroff.no"; # zone file path }; zone "stud.noroff.no" { type forward; forward only; forwarders { 172.24.111.20; 172.27.111.20; 172.21.111.20; 172.16.111.20; }; }; zone "studentdomene.noroff.no" { type forward; forward only; forwarders { 172.24.111.20; 172.27.111.20; 172.21.111.20; 172.16.111.20; }; }; zone "122.16.172.in-addr.arpa" { type master; file "/etc/named/zones/db.122.16.172"; # 172.16.122.0/24 subnet }; Any pointers would be greatly appreciated :) Kim

oVirt SHE smart-automated backup
by Vrgotic, Marko 26 Aug '20

26 Aug '20

Dear oVirt, For a while now I have been running backup of oVirt engine via ansible. And that works just fine. However, its still recommended, in SHE HA environment, especially for Restore purpose to have one of HA nodes in Maintenance mode, clean from Virtual load. Has anyone so far been able to automate oVirt engine backup in following or similar way: 1. Register on which HA node is SHE atm 2. Pick the other HA node to go into maintenance mode – in order to have one of HA nodes without virtual load 3. Verify it’s in maintenance mode 4. Execute engine-backup 5. Remove the maintenance mode of the node from step 2 Even if you are half way through, I would be happy to get involved and contribute. Kindly awaiting your reply. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

oVirt HCI 4.4.1 DR cannot import target volume after disaster
by wodel youchi 25 Aug '20

25 Aug '20

Hi, I have installed two HCI platforms. Then I set up the disaster-recovery configuration On source platform I did : # gluster volume set all cluster.enable-shared-storage enable # gluster system:: execute gsec_create # gluster volume geo-replication *source* gnodesen2-01.example.com::dest create push-pem # gluster volume geo-replication *source* gnodesen2-01.example.com::dest config use_meta_volume true On target platform I did : # gluster volume set *dest* features.shard enable I then realized these two tests : *1 - Sync data using the schedule_georep.py* a - Use the : "python3 /usr/share/glusterfs/scripts/schedule_georep.py source gnodesen2-01.example.com dest " command to sync data between the volumes b - After the sync is complete, execute "gluster volume dest set features.read-only off" c - Execute *import* (not create) *dest* volume on the target platform manually through the Admin-UI, Result : The domain could not be added and I get this error on vdsm log : " 2020-08-24 10:18:05,644+0100 ERROR (jsonrpc/5) [storage.HSM] Unexpected error (hsm:2843) Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/vdsm/storage/sd.py", line 456, in getVersion version = self.getMetaParam(DMDK_VERSION) File "/usr/lib/python3.6/site-packages/vdsm/storage/sd.py", line 452, in getMetaParam return self._metadata[key] File "/usr/lib/python3.6/site-packages/vdsm/storage/persistent.py", line 114, in __getitem__ return dec(self._dict[key]) File "/usr/lib/python3.6/site-packages/vdsm/storage/persistent.py", line 225, in __getitem__ return self._metadata[key] KeyError: 'VERSION' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/vdsm/storage/hsm.py", line 2829, in getStorageDomainsList dom = sdCache.produce(sdUUID=sdUUID) File "/usr/lib/python3.6/site-packages/vdsm/storage/sdc.py", line 115, in produce domain.getRealDomain() File "/usr/lib/python3.6/site-packages/vdsm/storage/sdc.py", line 51, in getRealDomain return self._cache._realProduce(self._sdUUID) File "/usr/lib/python3.6/site-packages/vdsm/storage/sdc.py", line 139, in _realProduce domain = self._findDomain(sdUUID) File "/usr/lib/python3.6/site-packages/vdsm/storage/sdc.py", line 156, in _findDomain return findMethod(sdUUID) File "/usr/lib/python3.6/site-packages/vdsm/storage/glusterSD.py", line 62, in findDomain return GlusterStorageDomain(GlusterStorageDomain.findDomainPath(sdUUID)) File "/usr/lib/python3.6/site-packages/vdsm/storage/fileSD.py", line 385, in __init__ manifest = self.manifestClass(domainPath) File "/usr/lib/python3.6/site-packages/vdsm/storage/fileSD.py", line 162, in __init__ sd.StorageDomainManifest.__init__(self, sdUUID, domaindir, metadata) File "/usr/lib/python3.6/site-packages/vdsm/storage/sd.py", line 352, in __init__ version = self.getVersion() * File "/usr/lib/python3.6/site-packages/vdsm/storage/sd.py", line 458, in getVersion raise se.MetaDataKeyNotFoundError("key={}".format(DMDK_VERSION))vdsm.storage.exception.MetaDataKeyNotFoundError: Meta Data key not found error: ('key=VERSION',)* 2020-08-24 10:18:05,644+0100 INFO (jsonrpc/5) [vdsm.api] FINISH getStorageDomainsList return={'domlist': []} from=::ffff:10.80.101.27,48282, flow_id=5209d576-ee09-4de3-bc46-0c186c6ad52a, task_id=bc93aaae-5449-4d0d-9884-f47ea542a963 (api:54) 2020-08-24 10:18:05,645+0100 INFO (jsonrpc/5) [jsonrpc.JsonRpcServer] RPC call Host.getStorageDomains succeeded in 3.01 seconds (__init__:312) 2020-08-24 10:18:05,754+0100 INFO (jsonrpc/4) [vdsm.api] START disconnectStorageServer(domType=7, spUUID='00000000-0000-0000-0000-000000000000', conList=[{'password': '********', 'vfs_type': 'glusterfs', 'port': '', 'mnt_options': 'backup-volfile-servers=10.90.101.23:10.90.101.25', 'iqn': '', 'connection': '10.90.101.21:/dest', 'ipv6_enabled': 'false', 'id': 'cc24df41-19b0-41ed-ae85-e091e40cc612', 'user': '', 'tpgt': '1'}], options=None) from=::ffff:10.80.101.27,48282, flow_id=5fcaf7d7-d3b6-4430-b5f9-28e6bd95656a, task_id=73654a43-c86b-4250-95d7-3e3399e5bc72 (api:48) 2020-08-24 10:18:05,754+0100 INFO (jsonrpc/4) [storage.Mount] unmounting /rhev/data-center/mnt/glusterSD/10.90.101.21:_dest (mount:215) " *Note :* I had to modify the line 105 from /usr/share/glusterfs/scripts/schedule_georep.py to be able to use it with python3 : -

oVirt node 4.4.1 deploy FQDN not reachable
by Roberto Nunin 25 Aug '20

25 Aug '20

Hi all I have an issue while trying to deploy hyperconverged solution on three ovirt node boxes. ISO used is ovirt-node-ng-installer-4.4.1-2020072310.el8.iso. When from cockpit I choose gluster deployment, I have a form where I can insert both gluster fqdn names and public fqdn names (that is what I need, due to distinct network cards & networks) If I insert right names, that are resolved by nodes, I receive, anyway, FQDN is not reachable below Host1 entries. As already stated, these names are certainly resolved by DNS used. Any hints about ? -- Roberto Nunin

Actual oVirt install questions
by David White 25 Aug '20

25 Aug '20

:) Ok, after all of the questions I've pestered you guys with, I'm actually getting started. Thank you all for your help. A few of questions right off the bat. For this install, I'm installing the latest (4.4.2) onto CentOS 8. 1) What's the difference between the `ovirt-hosted-engine-setup` command and the `engine-setup` command? I ran both of them, and it seems like they do the exact same thing. 2) For either of the commands above, I'm able to get as far as the step where it asks about the storage: Please specify the storage you would like to use (glusterfs, iscsi, fc, nfs)[nfs] It's clear to me that using this install method, the storage should be setup first / independently of the installer. So ok, I'll try the Cockpit install, since the documentation says that's the preferred method anyway. (I'm just a sucker for the command line, doing it myself, and understanding everything that I'm doing. I like to avoid GUIs if I can help it. LOL). So I logged into the Cockpit Dashboard at {ip-address}:9090, clicked on 'Virtualization' then clicked on Hosted Engine. Here, I clicked on Hyperconvered, and since I'm just installing to a single host right now, I clicked on Run Gluster Wizard for Single Node. So here's my 3rd question. 3) I can't get past the first step of this wizard. It is asking for the FQDN of the host (Host1). - The documentation indicates that this is NOT the base OS, but I've tried that - I've also tried the IP address that I intend to use for the manager (i.e. what I envision is akin to the vCenter IP address for a vSphere environment -- correct?) In both cases, the wizard won't let me proceed, and keeps saying "Host is not added to known_hosts" What am I missing, here? I'm familiar with the known_hosts file... but that's the VM / manager that I'm trying to create, I thought? Why does the wizard continue to give me that error message?

Is oVirt suited for supporting long-lived VMs than OpenStack?
by yam yam 24 Aug '20

24 Aug '20

Hi guys, I'm wondering why people say oVirt is better suited for traditional workloads like long-lived VMs than OpenStack. does oVirt have some additional features for it? Of course, VMs in OpenStack might be intentionally killed according to resource pressure if auto-scaling is used. but otherwise, I guess OpenStack has enough to run long-lived VMs. thanks.

Incremental VM backups
by Kevin Doyle 24 Aug '20

24 Aug '20

Hi I am looking at ways to backup VM's, ideally that support incremental backups. I have found a couple of python scripts that snapshot a VM and back it up but not incremental. The question is what do you use to backup the VM's ? (both linux and windows) Thanks Kevin

VMware import : older SSL version problems

using ovirt 4.4.1 to attempt to import from VMware, I have a problem with older SSL ciphers: libvirt.libvirtError: internal error: curl_easy_perform() returned an error: SSL connect error (35) : error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol where can I tell it "shut up and take the data"?

ovirt-imageio : can't upload / download
by Michael Jones 23 Aug '20

23 Aug '20

Hi, I have image upload/download working on some older ovirt servers where it still has the split daemon/proxy... on one newer one this feature is not working; software in use: CentOS 8 ovirt-engine-4.4.1.10-1.el8.noarch ovirt-imageio-client-2.0.9-1.el8.x86_64 ovirt-imageio-daemon-2.0.9-1.el8.x86_64 ovirt-imageio-common-2.0.9-1.el8.x86_64 the ui test button allowed me to work out 50-vdsm.conf was setting the wrong remote port... (was 54322, changed to 54323) updated remote with; [remote] host = 0.0.0.0 port = 54323 the test now passes, but on upload or download it still fails. Next i changed the control to be unix socket instead of tcp port 54324 (vdsm was giving an error: Image daemon is unsupported); I looked up the error line in the vdsm code, and found it was looking for unix socket: DAEMON_SOCK=/run/ovirt-imageio/sock switching to sock seemed to resolve all errors in the vdsm log; --- content of the imageio log; no errors as far as i can see: 2020-08-18

HCI Cluster Configuration
by Clint Boggio 20 Aug '20

20 Aug '20

Ovirt 4.3.9 HCI Gluster 3 Dell 730XD Managed Engine When I finished the "hosted engine deploy" I failed to add the gluster storage according to the documentation and i'd like to get that back on track. 1. I ticked the check box in the cluster configuration to "enable gluster service", all of my current gluster storage domains went "red triangle" on me and the hosts also went "red triangle" so I quickly changed it back and all went back to normal. Do I need to check that box to make the "Use Managed Gluster Volume" check box and drop down menu show my HCI gluster volumes that exist on the three nodes ? Do I need to put the storage domain(s) in maintenance mode to change them from unmanaged to managed ? Will the system honor the VM(s) that live in my "engine" and "vmstore" gluster volumes which are currently in use in the system if/when I change them from unmanaged to managed,or will the system wipe them and hose my managed engine and VMs ? Thank you for your help !

Hi Magnus, Sounds like you triggered this one https://bugzilla.redhat.com/show_bug.cgi?id=1555116. The error message you've got was meant to avoid removing a snapshot from a broken chain. On the Active VM snapshot -> Disks, is there any disk with Illegal status?

Re-creating ISO Storage Domain after Manager Rebuild
by bob.franzke＠mdaemon.com 19 Aug '20

19 Aug '20

Hi All, Late last year I had a disk issue with my Ovirt Manager Server that required I rebuild it and restored from backups. While this worked mostly, one thing that did not get put back correctly was the physical storage location of an ISO domain on the manager server. I believe this was previously set up as an NFS share being hosted on the Manager Server itself. The physical disk path and filesystem were not re-created on the manager server's local disk. So after the restore, the ISO domain shows up in the Ovirt Admin portal but shows the as down, and inactive. If I go into the domain, the 'Manage Domain' and 'Remove' buttons are not available. The only option I have for this is 'Destroy'. I right now have no ability to do things like boot a VM from a CD and am assuming its because the ISO domain that the images for this would be stored on is not available. How can I recreate this ISO domains to be able to upload ISO images that VM machines can boot from.The original path on the manager server was /gluster: sdc 8:32 0 278.9G 0 disk ├─sdc1 8:33 0 1G 0 part /boot └─sdc2 8:34 0 277.9G 0 part ├─centos_mydesktop-root 253:0 0 50G 0 lvm / ├─centos_mydesktop-swap 253:1 0 23.6G 0 lvm [SWAP] ├─centos_mydesktop-home 253:2 0 25G 0 lvm /home └─centos_mydesktop-gluster 253:3 0 179.3G 0 lvm /gluster The current layout is now: â””â”€sda3 8:3 0 277.7G 0 part â”œâ”€centos-root 253:0 0 50G 0 lvm / â”œâ”€centos-swap 253:1 0 4G 0 lvm [SWAP] â””â”€centos-home 253:2 0 223.7G 0 lvm /home Can I just create a new filesystem here, destroy the old ISO domain, and add a new one using the new path? I am a total Ovirt Noob so would appreciate any help here. Thanks. Bob

Upgrade Memory of oVirt Nodes
by souvaliotimaria＠mail.com 19 Aug '20

19 Aug '20

Hello everyone, I have an oVirt 4.3.2.5 hyperconverged 3 node production environment and we want to add some RAM to it. Can I upgrade the RAM without my users noticing any disruptions and keep the VMs running? The way I thought I should do it was to migrate any running VMs to the other nodes, then set one node in maintenance mode, shut it down, place the new memory, bring it back up, remove it from maintenance mode and see how the installation reacts and repeat for the other two nodes. Is this correct or should I follow another way? Will there be a problem during the time when the nodes will not be identical in their resources? Thank you for your time, Souvalioti Maria

OVirt hosted engine setup dnf config
by Raphael Höser 19 Aug '20

19 Aug '20

Hi all, I'm currently installing OVirt 4.4 on CentOS 8 in an hosted engine setup and it fails during ovirt-hosted-engine-setup. Because of our corporate proxy, some changes to the dnf.conf is needed (namely proxy_auth_method=basic) and the config is working fine when running dnf commands the normal way. Proxy configuration is provided via http_proxy, https_proxy and ftp_proxy env vars. The setup fails during a DNF call with status code 407 (proxy auth required). Is there another way to provide that config or any other way to resolve this? My googling didn't help me yet. On the same machine I had a running OVirt 4.3 on CentOS 7 running as a test and now wanted to upgrade (after a complete wipe). Thanks for your help, Raphael content of /etc/dnf/dnf.conf: [main] gpgcheck=1 installonly_limit=3 clean_requirements_on_remove=True best=True skip_if_unavailable=False proxy_auth_method=basic timeout=120 minrate=90 Log of ovirt-hosted-engine-setup: [ INFO ] Stage: Initializing [ INFO ] Stage: Environment setup During customization use CTRL-D to abort. Continuing will configure this host for serving as hypervisor and will create a local VM with a running engine.

Hi Magnus, You can find the VM's snapshot by sending a REST API request http://localhost:8080/ovirt-engine/api/vms/<vm-id>/snapshots/ You can also find the VM's snapshots (and view their parameters) by using SQL: select * from snapshots where vm_id = '<vm-id>'; You can also delete the relevant snapshot by specifying the snapshot's description: *delete from snapshots where description = '.....';* *Regards,* *Shani Leviim* On Tue, Aug 18, 2020 at 7:50 PM Magnus Isaksson <magnus(a)vmar.se> wrote: > Hi Shani > > Thanks for the help. > > What i can see it does not display any illegal statuses. > > I am a bit unsure how to delete it from the DB, how do i find the > snapshot_id? > > Cheers > Magnus > > ------------------------------ > *From:* Shani Leviim <sleviim(a)redhat.com> > *Sent:* 17 August 2020 13:45 > *To:* Magnus Isaksson <magnus(a)vmar.se> > *Cc:* users <users(a)ovirt.org> > *Subject:* Re: [ovirt-users] Help remove snapshot > > Hi Magnus, > Sounds like you triggered this one > https://bugzilla.redhat.com/show_bug.cgi?id=1555116. > The error message you've got was meant to avoid removing a snapshot from a > broken chain. > > On the Active VM snapshot -> Disks, is there any disk with Illegal status? > > Deleting the whole snapshot can be done from the DB: > *delete from snapshots where snapshot_id = '.....';* > > Although it's recommended to understand the root cause for that one. > > Can you please share your engine.log? > > > *Regards, * > > *Shani Leviim * > > > On Mon, Aug 17, 2020 at 1:37 PM Magnus Isaksson <magnus(a)vmar.se> wrote: > > Hi! > > I would need some help removing a snapshot that looks like this. > How do i remove it manually or fix snapshot definition? > ----------------- > Error while executing action: > > TUN_SALDC01: > > - The requested snapshot has an invalid parent, either fix the > snapshot definition or remove it manually to complete the process. > > ----------------- > And when i look at the disk on tha tnapshot it show as this: > > > And general info: > > _______________________________________________ > Users mailing list -- users(a)ovirt.org > To unsubscribe send an email to users-leave(a)ovirt.org > Privacy Statement: https://www.ovirt.org/privacy-policy.html > oVirt Code of Conduct: > https://www.ovirt.org/community/about/community-guidelines/ > List Archives: > https://lists.ovirt.org/archives/list/users@ovirt.org/message/5QEBPZPUHDGS5… > >

HA Storage options
by David White 19 Aug '20

19 Aug '20

Hi, I started an email thread a couple months ago, and felt like I got some great feedback and suggestions on how to best setup an oVirt cluster. Thanks for your responses thus far.My goal is to take a total of 3-4 servers that I can use for both the storage and the virtualization, and I want both to be highly available. You guys told me about oVirt Hyperconverged with Gluster, and that seemed like a great option. However, I'm concerned that this may not actually be the best approach. I've spoken with multiple people at Red Hat who I have a relationship with (outside of the context of the project I'm working on here), and all of them have indicated to me that Gluster is being deprecated, and that most of the engineering focus these days is on Ceph. I was also told by a Solutions Architect who has extensive experience with RHV that the hyperconverged clusters he used to build would always give him problems. Does oVirt support DRBD or Ceph storage? From what I can find, I think that the answer to both of those is, sadly, no. So now I'm thinking about switching gears, and going with iSCSI instead. But I'm still trying to think about the best way to replicate the storage, and possibly use multipathing so that it will be HA for the VMs that rely on it. Has anyone else experienced problems with the Gluster hyperconverged solution? Am I overthinking this whole thing, and am I being too paranoid? Is it possible to setup some sort of software-RAID with multiple iSCSI targets? As an aside, I now have a machine that I was planning to begin doing some testing and practicing with. Previous to my conversations with the folks at Red Hat, I was planning on doing some initial testing and config with this server before purchasing another 2-3 servers to build the hyperconverged cluster.

Cannot access Engine VM
by Steven Bach 18 Aug '20

18 Aug '20

Hello All, I installed Ovirt node 4.4.1.5 from the ovirt ISO, IP 192.168.1.53/24 I setup the self hosted engine by logging into the web interface, configured it for 192.168.1.55/24 IP on the default generated bridge interface and setup a FQDN that is resolvable via DNS. Setup NFS storage, and all seems good. The Engine VM is running, but I cannot access it at all outside the node. SSH'd in the node I can ping the engine, anything else on that same subnet cannot SSH or even ping it (Again, DNS is resolving correctly to the IP Address). I am able to SSH into the engine from the node. While SSH'd into the Engine from the node, I can only ping the Node and nothing beyond that, not able to install ovirt repo, nothing. Any ideas are greatly appreciated, thank you, -- Steven Bach sbach(a)bachnetworks.com

How to diable dhcp in ovirt network
by Adam Xu 17 Aug '20

17 Aug '20

Hi everyone Recently, when I install okd on ovirt. The installation process was failed because the vm automatically acquired an IP address from DHCP before the installer assigned it. Our DHCP is enabled by a layer 3 switch, I tried to diable dhcp using network filter. but there is no entry related to blocking the DHCP feature. Is there any way for ovirt to disable DHCP? -- Adam Xu

oVirt nested on oVirt works, when you enable MAC spoofing on host VMs
by thomas＠hoberg.net 13 Aug '20

13 Aug '20

Howto: Create a new network profile that doesn't have the MAC spoofing filter included. In my case I used one without any filters, you may want to be more careful. Background: I had tried the nested approach with the default settings and found that the hosted-engine setup worked just find to the point where it was running as a nested VM on the install node, but that it failed to tie in the other gluster nodes or to communicate to the outside: There was something wrong with the network, but no obivous failures. I tried using other, simpler "client hypervisors" (it's all KVM anyway) VirtualBox and 'native' KVM and the symptoms were the same: The VMs ran just fine, but the network didn't connect. And then I remembered that obviously a Hypervisor need to override the MAC for each client VM if you want full network access and I had come across "no-mac-spoofing" often enough it somehow stayed on my mind... and finally it clicked. Anyhow, validing full functionality now and the main interest in this is the ability to do a full simulation/testing of oVirt 4.3->4.4 upgrades on 3-node HCI setups, which I'd rather not do on the live physical system. Of course, it's also quite cool!

Support for Shared SAS storage

Hello, I’ve two compute nodes with SAS Direct Attached sharing the same disks. Looking at the supported types I can’t see this on the documentation: https://www.ovirt.org/documentation/admin-guide/chap-Storage.html There’s is local storage on this documentation, but my case is two machines, both using SAS, connected to the same machines. It’s the VRTX hardware from Dell. Is there any support for this? It should be just like Fibre Channel and iSCSI, but with SAS instead. Thanks,

Is the udev settling issue more wide spread? Getting failed 'qemu-img -convert' also while copying disks between data and vmstore domains
by thomas＠hoberg.net 12 Aug '20

12 Aug '20

While trying to diagnose an issue with a set of VMs that get stopped for I/O problems at startup, I try to deal with the fact that their boot disks cause this issue, no matter where I connect them. They might have been the first disks I ever tried to sparsify and I was afraid that might have messed them up. The images are for a nested oVirt deployment and they worked just fine, before I shut down those VMs... So I first tried to hook them as secondary disks to another VM to have a look, but that just cause the other VM to stop at boot. Also tried downloading, exporting, and plain copying the disks to no avail, OVA exports on the entire VM fail again (fix is in!). So to make sure copying disks between volumes *generally* work, I tried copying a disk from a working (but stopped) VM from 'vmstore' to 'data' on my 3nHCI farm, but that failed, too! Plenty of space all around, but all disks are using thin/sparse/VDO on SSD underneath. Before I open a bug, I'd like to have some feedback if this is a standard QA test, this is happening to you etc. Still on oVirt 4.3.11 with pack_ova.py patched to wait for the udev settle, This is

oVirt 4.4.0 Release is now generally available
by Sandro Bonazzola 12 Aug '20

12 Aug '20

oVirt 4.4.0 Release is now generally available The oVirt Project is excited to announce the general availability of the oVirt 4.4.0 Release, as of May 20th, 2020 This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics, as compared to oVirt 4.3. Important notes before you install / upgrade Some of the features included in the oVirt 4.4.0 release require content that will be available in CentOS Linux 8.2 but cannot be tested on RHEL 8.2 yet due to some incompatibility in the openvswitch package that is shipped in CentOS Virt SIG, which requires rebuilding openvswitch on top of CentOS 8.2. The cluster switch type OVS is not implemented for CentOS 8 hosts. Please note that oVirt 4.4 only supports clusters and datacenters with compatibility version 4.2 and above. If clusters or datacenters are running with an older compatibility version, you need to upgrade them to at least 4.2 (4.3 is recommended). Please note that in RHEL 8 / CentOS 8 several devices that worked on EL7 are no longer supported. For example, megaraid_sas driver is removed. If you use Enterprise Linux 8 hosts you can try to provide the necessary drivers for the deprecated hardware using the DUD method (See users mailing list thread on this at https://lists.ovirt.org/archives/list/users@ovirt.org/thread/NDSVUZSESOXEFJ… ) Installation instructions For the engine: either use the oVirt appliance or install CentOS Linux 8 minimal by following these steps: - Install the CentOS Linux 8 image from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm - dnf update (reboot if needed) - dnf module enable -y javapackages-tools pki-deps postgresql:12 - dnf install ovirt-engine - engine-setup For the nodes: Either use oVirt Node ISO or: - Install CentOS Linux 8 from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8…, selecting the minimal installation. - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm - dnf update (reboot if needed) - Attach the host to the engine and let it be deployed. Update instructionsUpdate from oVirt 4.4 Release Candidate On the engine side and on CentOS hosts, you’ll need to switch from ovirt44-pre to ovirt44 repositories. In order to do so, you need to: 1. dnf remove ovirt-release44-pre 2. rm -f /etc/yum.repos.d/ovirt-4.4-pre-dependencies.repo 3. rm -f /etc/yum.repos.d/ovirt-4.4-pre.repo 4. dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm 5. dnf update On the engine side you’ll need to run engine-setup only if you were not already on the latest release candidate. On oVirt Node, you’ll need to upgrade with: 1. Move node to maintenance 2. dnf install https://resources.ovirt.org/pub/ovirt-4.4/rpm/el8/noarch/ovirt-node-ng-imag… 3. Reboot 4. Activate the host Update from oVirt 4.3 oVirt 4.4 is available only for CentOS 8. In-place upgrades from previous installations, based on CentOS 7, are not possible. For the engine, use backup, and restore that into a new engine. Nodes will need to be reinstalled. A 4.4 engine can still manage existing 4.3 hosts, but you can’t add new ones. For a standalone engine, please refer to upgrade procedure at https://ovirt.org/documentation/upgrade_guide/#Upgrading_from_4-3 If needed, run ovirt-engine-rename (see engine rename tool documentation at https://www.ovirt.org/documentation/admin-guide/chap-Utilities.html ) When upgrading hosts: You need to upgrade one host at a time. 1. Turn host to maintenance. Virtual machines on that host should migrate automatically to a different host. 2. Remove it from the engine 3. Re-install it with el8 or oVirt Node as per installation instructions 4. Re-add the host to the engine Please note that you may see some issues live migrating VMs from el7 to el8. If you hit such a case, please turn off the vm on el7 host and get it started on the new el8 host in order to be able to move the next el7 host to maintenance. What’s new in oVirt 4.4.0 Release? - Hypervisors based on CentOS Linux 8 (rebuilt from award winning RHEL8), for both oVirt Node and standalone CentOS Linux hosts. - Easier network management and configuration flexibility with NetworkManager. - VMs based on a more modern Q35 chipset with legacy SeaBIOS and UEFI firmware. - Support for direct passthrough of local host disks to VMs. - Live migration improvements for High Performance guests. - New Windows guest tools installer based on WiX framework now moved to VirtioWin project. - Dropped support for cluster level prior to 4.2. - Dropped API/SDK v3 support deprecated in past versions. - 4K block disk support only for file-based storage. iSCSI/FC storage do not support 4K disks yet. - You can export a VM to a data domain. - You can edit floating disks. - Ansible Runner (ansible-runner) is integrated within the engine, enabling more detailed monitoring of playbooks executed from the engine. - Adding and reinstalling hosts is now completely based on Ansible, replacing ovirt-host-deploy, which is not used anymore. - The OpenStack Neutron Agent cannot be configured by oVirt anymore, it should be configured by TripleO instead. This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.1 * CentOS Linux (or similar) 8.1 This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.1 * CentOS Linux (or similar) 8.1 * oVirt Node 4.4 based on CentOS Linux 8.1 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed. If you manage more than one oVirt instance, OKD or RDO we also recommend to try ManageIQ <http://manageiq.org/>. In such a case, please be sure to take the qc2 image and not the ova image.

Reverting to Snapshot
by Christian Reiss 12 Aug '20

12 Aug '20

Hey folks, this, I hope, is a trivial question. But I really can't find the button for it. If you take a snapshot of any vm - how do you revert to that snapshot, discarding all changes after? I see options to clone, delete, take snapshot, preview... but revert? Really in the true sense of "discard all changes, go back to this snapshot state". What am I not seeing here? :) -- with kind regards, mit freundlichen Gruessen, Christian Reiss

oVirt Node 4.1.1 Hosted Engine Deployment Fibre Channel No LUNS found
by hkexdong＠yahoo.com.hk 12 Aug '20

12 Aug '20

I've an external RAID subsystem connect to the host by SAS cable (SFF-8644). I follow the instructions of the RAID card manufacture. Include the driver during host installation. And I can see the created RAID volumes (LUNs) available in "Installation Destination". Although I choose to install the engine in host local disk. The installation success and I proceed to hosted engine deployment by Cockpit. And now I stuck at part 4 Storage. I believe "Storage Type" select "Fibre Channel" is correct even I'm not using fibre cable. As NFS and iSCSI are utilize network. I confirm there are 2 RAID volume (LUN0 & LUN1) created in the external RAID subsystem. Why oVirt cannot discover them. What could be wrong :(

Hosted Engine Deployment stuck at 3. Prepare VM
by hkexdong＠yahoo.com.hk 12 Aug '20

12 Aug '20

oVirt Node version is 4.4.1. This version can successful deploy before. But after I compile the RAID driver. It now stuck at Prepare VM. The last message is "[ INFO ] TASK [ovirt.hosted_engine_setup : Install ovirt-engine-appliance rpm]" According to the instructions from RAID controller manufacture. I'd install the "kernel-headers-xxx.rpm" and "kernel-devel-xxx.rpm" which extracted from official CentOS 8.2.2004 ISO. Also include a bunch of packages for compile driver (e.g. gcc, make, zlib-devel, etc.) I think those packages ruined the deployment. But I still want to know it actually stuck at which part and the reason. Is there any way to check the deployment log?

by Jiří Sléžka 11 Aug '20

11 Aug '20

Hello, better start new thread... it looks like tls1.0 is not supported anymore in ovirt-engine-extension-aaa-ldap I just migrated engine from 4.3 to 4.4 and cannot use my ldap profile because server_error: The connection reader was unable to successfully complete TLS negotiation: SSLHandshakeException(The server selected protocol version TLS10 is not accepted by client preferences [TLS12]), ldapSDKVersion=4.0.14, revision=c0fb784eebf9d36a67c736d0428fb3577f2e25bb but when I try to force tls 1.0 by setting ... pool.default.ssl.startTLS = true pool.default.ssl.startTLSProtocol = TLSv1 ... I got server_error: The connection reader was unable to successfully complete TLS negotiation: SSLHandshakeException(No appropriate protocol (protocol is disabled or cipher suites are inappropriate)), ldapSDKVersion=4.0.14, revision=c0fb784eebf9d36a67c736d0428fb3577f2e25bb I can't switch to something better on server side, is it possible to allow weak ciphers/protocols on client side? Thanks in advance, Jiri

migrating standalone engine to selfhosted and upgrade from 4.3 to 4.4 in one step
by Jiří Sléžka 11 Aug '20

11 Aug '20

Hello, I have 4 host cluster managed with standalone engine in version 4.3 and I would like to migrate this standalone engine to 4.4 as hosted engine. I have two new hosts which I would like to use as base for new HE cluster. (new hosts are Intel based, old ones are AMD Opteron based - new cluster will have 4.4 compatibility, old one have to stay at 4.2 compatibility level). I red this https://www.ovirt.org/documentation/migrating_from_a_standalone_manager_to_… but the question is: Can I migrate and upgrade in one step? Have anybody did that already? If it is not possible what is a suggested approach? Thanks for help Jiri
