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

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 !

Re: Help remove snapshot
by Shani Leviim 20 Aug '20

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… >

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).

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

Uploading images from the UI was available in ovirt 4.4.0, but is fully functional since ovirt 4.4.1.
