Issue with ovirt 4.4 after doing some incremental backups.

Hello, After doing a few vm backups, something breaks and I am unable to perform any operations. I cannot do incremental backups and even full backups doesn't work. I have this issue third time. I don't know how to fix this so I am currently making new vms for testing purposes VDSM ovirt44-h2.storware.local command StartVmBackupVDS failed: Backup Error: {'vm_id': '116aa6eb-31a1-43db-9b1e-ad6e32fb9260', 'backup': <vdsm.virt.backup.BackupConfig object at 0x7f42602bba20>, 'reason': "Error starting backup: internal error: unable to execute QEMU command 'transaction': Dirty bitmap 'ef0dfe55-c08c-4d9e-ad32-d6b6d5cbdac6' not found"} Best Regards, Łukasz Kołaciński Junior Java Developer e-mail: l.kolacinski(a)storware.eu<mailto:l.kolacinski@storware.eu> <mailto:m.helbert@storware.eu> [STORWARE]<http://www.storware.eu/> ul.

Hi oVirt land Hope you are well. Don't even know what to call this. But let me describe what I want to achieve. We have a cluster with say 100 vm's. But we want two use two hosts in the cluster two run only certain VM's. I think you can do that with affinity rules. But how can I restrict those two hosts to only run the VM's, meaning that no other VM's will run on them. I don't want to go and edit the 100 other VM's to not run on 2 hosts. Is there an easy way for doing this? Oracle VM uses pools, I dont know what vmware uses. Any advice will help. Regards Nar

Management Engine IP change
by Anton Louw 28 Jul '20

28 Jul '20

Hi All, Does somebody perhaps know the process of changing the Hosted Engine IP address? I see that it is possible, I am just not sure if it is a straight forward process using 'nmtui' or editing the network config file. I have also ensured that everything was configured using the FQDN. Thanks Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

CentOS 8.2, ovVirt 4.4.1.8, SHE -- kernel: device-mapper: core: ovirt-ha-broker: sending ioctl 5401 to DM device without required privilege
by Dmitry Kharlamov 28 Jul '20

28 Jul '20

Good day! CentOS 8.2.2004 (Core), ovVirt 4.4.1.8-1.el8, storage type FC with multipathing. Please tell me what could be the problem. Messages are constantly poured into the console and / var / log / messages: kernel: device-mapper: core: ovirt-ha-broker: sending ioctl 5401 to DM device without required privilege Messages appeared during the installation process (SHE via CLI), during the LUN partitioning phase, and after that they do not stop. At the same time, the installation was successful and now everything is working fine. A similar problem is described here, but no solution has been proposed: https://bugzilla.redhat.com/show_bug.cgi?id=1838453 Best regards, Dmitry

Re: Failed to execute stage 'Environment customization': IPAddress() does not support netmasks or subnet prefixes! See documentation for details.
by James Loker-Steele 28 Jul '20

Hi Anton, I tried without the /24 it threw an error saying it wasn’t a correct cidr address 10.93.130.50/64 (it added the /64) Interesting though, I have manually created the ovirtmgmt bridge interface and assigned an IP address to it (as per another post) and it has gone past this step now without the /24. The part I am crashing out on is being unable to resolve the address. I can post the error shortly. This is strange behaviour as the host can resolve, but I will be adding dns addresses to the ovirtmgmt interface and trying again(post didn’t show to add them) When I installed <4.2 I didn’t get these issues it went smoothly. The problems seem related to ansible.

Adding hypervisor fails, yum links deprecated (Centos 7.7/ oVirt 4.3)
by wjb2130＠cumc.columbia.edu 28 Jul '20

28 Jul '20

Greetings. In a multi-hypervisor environment, we are running Centos 7.7.1908, with ovirt-4.3. There are problems adding a new hypervisor, because all the yum resources have switched in favor of newer versions. Is there a proceedure to add a hypervisor under the oVirt Virtualization manager while retaining an older, known working OS version like Centos 7.7.1908 ? Upgrading everything across the board isn't an immediate option. There are many VMs and hypervisors in production, and can't be disturbed. In sum: is it still possible to install known working 4.30.33-1.el7? All that is presented now is 4.30.46-1.el7 I ran: yum install vdsm-4.30.33-1.el7.x86_64. This completed. However, when I tried to add the resulting hypservisor using the oVirt web UI, that fails. Logs on that management server showed that the install process insists on using 4.30.46-1.el7. Any way to avoid this? 2020-07-22 20:30:58,621-04 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (VdsDeploy) [45782a5f] EVENT_ID: VDS_INSTALL_IN_PROGRESS_ERROR(511), An error has occurred during installation of Host hypervisor7: Failed to execute stage 'Package installation': [u'vdsm-4.30.46-1.el7.x86_64 requires lvm2 >= 7:2.02.186-7.el7_8.1'].

change lun for hosted_engine use?
by Philip Brown 28 Jul '20

28 Jul '20

I currently have a self-hosted engine, running in a dedicated ISCSI storage domain. I'd like to change the backend hardware for the storage. i think there's some longwinded and complicated method of shutting down the engine, backup, creating a NEW one, restore, and whoknowswhat. I was wondering though, if maybe there's a way to just add an iscsi lun to the storage domain, and tell ovirt, "Hey, move the stuff over to that other lun" ? Ive added the new lun already :) havent found a reference to move the files' residence though. If it helps, my end goal is to remove that lun completely. -- Philip Brown| Sr. Linux System Administrator | Medata, Inc. 5 Peters Canyon Rd Suite 250 Irvine CA 92606 Office 714.918.1310| Fax 714.918.1325 pbrown(a)medata.com| www.medata.com

Deploying new Ovirt Node on new 4.4 cluster. ansible code incorrect
by erin.sims＠bookit.com 27 Jul '20

27 Jul '20

Hi Guys we attempted to deploy a new ovirt cluster two weeks ago. 4.4.1 and 4.4.0 Once we got the engine up we tried to add a new node and Ansible began to fail on the deploy scripts. I search the logs and discovered the Ansible script was not evaluating the right versions of python, python3. Also the yum module should of been dnf. Once i change those in many places it worked great.

Centos based Ovirt 4.3.10.4-1.el7, VMs cannot communicate over VM networks
by Konstantinos B 27 Jul '20

27 Jul '20

Hi all Can anyone point into the right direction on how to troubleshoot VM connectivity between VM networks? The nodes have been double-installed from the engine. The external ovn-provider is reachable through HTTP. ovs-vsctl shows the interfaces once a VM is booted. However, no traffic is passed between VMs. Any help is greatly appreciated.

problem with custom bond options
by Jiří Sléžka 27 Jul '20

27 Jul '20

Hello, CentOS8, oVirt 4.4.1.10-1.el8 I am trying to setup active-backup (mode=1) bonding mode with custom properties. I have one 10GE switch, the second is just 1G. 10GE link is the primary one. cat /etc/sysconfig/network-scripts/ifcfg-bond0 BONDING_OPTS="active_slave=ens5 downdelay=0 miimon=100 mode=active-backup primary=ens5 updelay=0" TYPE=Bond BONDING_MASTER=yes PROXY_METHOD=none BROWSER_ONLY=no IPV4_FAILURE_FATAL=no IPV6_DISABLED=yes IPV6INIT=no NAME=bond0 UUID=c054364e-47cf-47ee-a7fc-70b37c9977e7 DEVICE=bond0 ONBOOT=yes MTU=9000 When I try to add a custom parameter "fail_over_mac=active" (which I believe could solve my problems with stalled mac addresses in switch's cam table in case of failover) I got... "Error while executing action HostSetupNetworks: Unexpected exception" ...in manager.

I believe a MAC address is not configured in interface configuration. Or does it mean 'fail_over_mac=active' is not supported in oVirt? Thanks in advance, Jiri

Re: Ovirt SYSTEM user does not allow deletion of VM networks
by Konstantinos B 25 Jul '20

25 Jul '20

I've deleted them from the cluster as well but re-appear. I've removed ovirt-engine through engine-cleanup installed again and they reappear. Removed ovirt-engine deleted all "ovirt*" files and currenty trying to re-install. I've checked the host's ovs-vsctl bridges and only the desired are shown. So i believe it's an issue on the engine itself.

Shutdown procedure for single host HCI Gluster
by Gianluca Cecchi 25 Jul '20

25 Jul '20

Hello, I'm testing the single node HCI with ovirt-node-ng 4.3.9 iso. Very nice and many improvements over the last time I tried it. Good! I have a doubt related to shutdown procedure of the server. Here below my steps: - Shutdown all VMs (except engine) - Put into maintenance data and vmstore domains - Enable Global HA Maintenance - Shutdown engine - Shutdown hypervisor It seems that the last step doesn't end and I had to brutally power off the hypervisor. Here the screenshot regarding infinite failure in unmounting /gluster_bricks/engine https://drive.google.com/file/d/1ee0HG21XmYVA0t7LYo5hcFx1iLxZdZ-E/view?usp=… What would be the right step to do before the final shutdown of hypervisor? Thanks, Gianluca

RDP
by eevans＠digitaldatatechs.com 24 Jul '20

24 Jul '20

I am using Ovirt 4.3. I followed the instructions for get RDP to work for a user, but admin@internal is the only user the RDP will launch for. The other test users I created and are added to the Remote Desktop Users group which is the permission I assigned to the VM's as well as the user name. I added users first, then the group to see if it would help. So far, admin@internal, the Ovirt admin user, is the only user RDP will work for. I know I am missing something, I'm just not sure what. Any help would be appreciated. Eric.

very very bad iscsi performance
by Philip Brown 24 Jul '20

24 Jul '20

I'm trying to get optimal iscsi performance. We're a heavy iscsi shop, with 10g net. I'mm experimenting with SSDs, and the performance in ovirt is way, way less than I would have hoped. More than an order of magnitude slower. here's a datapoint. Im running filebench, with the OLTP workload. First, i run it on one of the hosts, that has an SSD directly attached. create an xfs filesystem (created on a vg "device" on top of the SSD), mount it with noatime, and run the benchmark. 37166: 74.084: IO Summary: 3746362 ops, 62421.629 ops/s, (31053/31049 r/w), 123.6mb/s, 161us cpu/op, 1.1ms latency I then unmount it, and make the exact same device an iscsi target, and create a storage domain with it. I then create a disk for a VM running *on the same host*, and run the benchmark. The same thing: filebench, oltp workload, xfs filesystem, noatime. 13329: 91.728: IO Summary: 153548 ops, 2520.561 ops/s, (1265/1243 r/w), 4.9mb/s, 289us cpu/op, 88.4ms latency 62,000 ops/s vs 2500 ops/s. what???? Someone might be tempted to say, "try making the device directly available, AS a device, to the VM". Unfortunately,this is not an option. My goal is specifically to put together a new, high performing storage domain, that I can use as database devices in VMs. I'm not expecting the same 62,000 ops/second. but I was expecting at *least* 5,000. Ideally more like 10,000. -- Philip Brown| Sr. Linux System Administrator | Medata, Inc. 5 Peters Canyon Rd Suite 250 Irvine CA 92606 Office 714.918.1310| Fax 714.918.1325 pbrown(a)medata.com| www.medata.com

qemu-guest-agent on Ubuntu doesn't report FQDN
by Florian Schmid 24 Jul '20

24 Jul '20

Hi, I have a problem with Ubuntu 20.04 VM reporting the correct FQDN to the engine. Starting with this release, the ovirt-guest-agent is not available anymore. Therefore, I have installed qemu-geust-agent with package defaults. Now in the Engine, I only see the hostname under FQDN tab, instead the real full name with domain. I'm running an oVirt environment on 4.3.8. The VM is resolveable, forward and reverse DNS entries are working. hostname -f shows the correct FQDN. Even adding IP and FQDN to /etc/hosts file doesn't change anything. qemu-guest-agent version: 4.2-3ubuntu6.3 I manage this VM via ansible 2.9 and ansible is able to get the FQDN of the VM without any issues... What can I do here to debug my issue? Does the engine cache the wrong result? Even after stopping and starting the VM again, engine is only showing the hostname instead of the FQDN. Best regards, Florian

iSCSI multipath with separate subnets... still not possible in 4.4.x?
by Mark R 24 Jul '20

24 Jul '20

I'm looking through quite a few bug reports and mailing list threads, but want to make sure I'm not missing some recent development. It appears that doing iSCSI with two separate, non-routed subnets is still not possible with 4.4.x. I have the dead-standard iSCSI setup with two separate switches, separate interfaces on hosts and storage, and separate subnets that have no gateway and are completely unreachable except from directly attached interfaces. The hosted-engine comes up with multiple paths and everything is perfect, but that's because Ansible/hosted-engine deploy script have configured things correctly. Once you need to import or add new storage domains, it's not possible to do so in a way that gets both paths connected *and* persists across host reboots. Following the docs to create 'iSCSI Multipath" bonds (plural, you can _not_ create a single bond that includes both interfaces and hope things route correctly... oVirt will try to connect from the interface for storage network A to the target on storage network B, which can't happen since they are not routed (and should not be). So, there's nothing in the docs about how you can accomplish multipathing, but there are a few mailing list messages that say "just create two separate "iSCSI Multipath" bonds in the datacenter, one for each of your two interfaces. You can do this, and you'll get hopeful that things might work now. You can do discovery and it succeeds, because no more trying to connect to unreachable targets. However, and big caveat, there's no way to tell this new/imported domain, "Oh, use this other interface as well, so you have redundant paths". Once the domain is attached and activated, you have a single path. You can then manage the domain, do a discovery, see a path that isn't connected yet, and log into it as well. Now you have two paths, is everything right with the world?!? Nope, it's impossible to persist that connection, it will be gone on next reboot and you'll always have to manually visit each host, do discovery, and login. Nothing in the UI allows you to "Save" that second connection in a way that it will be used again. Clicking "OK" does not, and going back to the "iSCSI Multipath" area of the Data Center you can't edit each of the bonds and make sure each logical network has every possible target checked, because these targets you've manually logged into are never listed in that area of the UI. So I really, really hope I'm wrong because I'd like to move past this snag and onto the next one (which is that bond interfaces in 4.4.x will not allow you to attach additional networks... works great in 4.3, appears broken in 4.4.x). But, no sense chasing that yet if iSCSI multipath isn't possible, which is looking likely. Has anyone had success, running iSCSI in by far the most common setup out there, but also in a way oVirt really doesn't want to let you? This is driving me nuts, I've paved and rebuilt these hosts dozens of times now, trying different methods in the hopes of getting multipath that persists.

Re: oVirt 4.3 ssh passwordless setup guide
by Strahil Nikolov 24 Jul '20

24 Jul '20

You need to keep the ssh root access from the engine , so you will need a 'Match' stanza for the engine. Of course testing is very important, but in case you got no test setup - you can set a node in maintenance and experiment a little bit.

Upgrade from 4.3 to 4.4 fails with db or user ovirt_engine_history already exists
by wilderink＠triplon.nl 23 Jul '20

23 Jul '20

Currently, our upgrade to 4.4 fails with error: FATAL: Existing database 'ovirt_engine_history' or user 'ovirt_engine_history' found and temporary ones created We have upgraded the running 4.3 installation to the latest version and also use the latest packages for the upgrade on the new CentOS 8.2 installation. The back-up is made following the Hosted Engine upgrade steps in the manual, using: `engine-backup --scope=all --mode=backup --file=backup.bck --log=backuplog.log` The upgrade is performed after copying the backup.bck file to the new server and using `hosted-engine --deploy --restore-from-file=backup.bck` After creating the Engine VM, the installation process hangs when the backup is restored. We tried it several times, using a complete or a partial back-up. Old/current oVirt version: 4.3.10.4-1.el7 New version: 4.4.1.8 ovirt-ansible-hosted-engine-setup: 1.1.6 Did anyone get the same error while upgrading an existing installation? Thanks!

oVirt 4.4 Engine data migration & GUI notes
by Andrei Verovski 23 Jul '20

23 Jul '20

Hi ! I have installed new oVirt 4.4 Engine (as separate entity, not hosted engine) and migrated data from old 4.3 installation. Everything went smooth. Q: Which PostgreSQL password now active - new one I entered during install or old which could migrate with old data? I noticed GUI changes straight on dashboard. Icons on top (data centres, clusters, hosts, etc) are simply put, too huge. This serves no useful purpose whatsoever, and consumes screen real estate for no reason. Decreasing their size by 2/3 will help to make 1st page more informative at 1st sight without extra scrolling. with best regards Andrei

HostedEngine start error: could not find capabilities for arch=x86_64 domaintype=kvm
by Gianluca Cecchi 23 Jul '20

23 Jul '20

Hello, I'm importing a VM into a new oVirt environment that is in 4.3.10: the new host is the same as the previous one (only difference it is in 4.3.10 while the old one in 4.3.9). This VM acted as a single host HCI environment (with 4.3.9). I imported the storage domain containing the VM and its disks and the VM boots ok. Now its Hosted Engine VM (that is so a nested VM) doesn't start. I think it was good when I stopped/detached it... and so I would like to cross check and verify if I missed something configuring the new environment or something changed from 4.3.9 to 4.3.10 In vdsm.log I see this reason: 2020-07-23 14:38:20,489+0200 ERROR (vm/9233dc8b) [virt.vm] (vmId='9233dc8b-7a4d-4fac-8551-dc7407f36548') The vm start process failed (vm: 934) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 868, in _startUnderlyingVm self._run() File "/usr/lib/python2.7/site-packages/vdsm/virt/vm.py", line 2892, in _run dom = self._connection.defineXML(self._domain.xml) File "/usr/lib/python2.7/site-packages/vdsm/common/libvirtconnection.py", line 131, in wrapper ret = f(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/common/function.py", line 94, in wrapper return func(inst, *args, **kwargs) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 3743, in defineXML if ret is None:raise libvirtError('virDomainDefineXML() failed', conn=self) libvirtError: invalid argument: could not find capabilities for arch=x86_64 domaintype=kvm The relevant parts of the generated xml in vdsm.log seems: 2020-07-23 14:38:20,487+0200 INFO (vm/9233dc8b) [virt.vm] (vmId='9233dc8b-7a4d-4fac-8551-dc7407f36548') <?xml version="1.0" encoding="ut f-8"?><domain type="kvm" xmlns:ns0="http://ovirt.org/vm/tune/1.0" xmlns:ovirt-vm="http://ovirt.org/vm/1.0"> <name>HostedEngine</name> <uuid>9233dc8b-7a4d-4fac-8551-dc7407f36548</uuid> <memory>16777216</memory> <currentMemory>16777216</currentMemory> <iothreads>1</iothreads> <maxMemory slots="16">67108864</maxMemory> <vcpu current="2">32</vcpu> <sysinfo type="smbios"> <system> <entry name="manufacturer">oVirt</entry> <entry name="product">oVirt Node</entry> <entry name="version">7-7.1908.0.el7.centos</entry> <entry name="serial">704e1338-5dec-46f8-a186-8c2080dcefd8</entry> <entry name="uuid">9233dc8b-7a4d-4fac-8551-dc7407f36548</entry> </system> </sysinfo> <clock adjustment="0" offset="variable"> <timer name="rtc" tickpolicy="catchup"/> <timer name="pit" tickpolicy="delay"/> <timer name="hpet" present="no"/> </clock> <features> <acpi/> </features> <cpu match="exact"> <model>Skylake-Server</model> <feature name="spec-ctrl" policy="require"/> <feature name="ssbd" policy="require"/> <feature name="md-clear" policy="require"/> <topology cores="2" sockets="16" threads="1"/> <numa> <cell cpus="0,1" id="0" memory="16777216"/> </numa> </cpu> <cputune/> ... </metadata> <on_poweroff>destroy</on_poweroff><on_reboot>destroy</on_reboot><on_crash>destroy</on_crash></domain> (vm:2890) Any insights?

oVirt Network problem.
by Emil Dumitrache 22 Jul '20

22 Jul '20

Hello, I am new to oVirt. I have a problem and I don't know how to deal with it, i added another network besides the management network and after that the node did not respond to the oVIrt manager. I had to change the DNS to the new IP of the new network so that oVIrt manager can manage it. Now i have an error: Out-of-sync: Default route: host true, DC false. I checked on the node and the second network has DEFROUTE=NO and the management network to yes. I don't know why the manager is seeing that. Also the management IP does not respond to ping or anything. Please some advice for a newbie? The setup is: A standalone server with Centos7 and oVIrt manager installed and a node with ovirt node os. Thank you.

Reinstall failed on 4.4.1.1 with custom kernel settings
by mmarino＠extraordy.com 22 Jul '20

22 Jul '20

Hi, after the upgrade from 4.4.1 to 4.4.1.1, it seems that I cannot reinstall adding custom kernel settings. In my case, I'm trying to add "ixgbe.allow_unsupported_sfp=1" to cmdline but reinstall process fails without showing any relevant error in /var/log/vdsm/vdsm.log. I did the same test on version 4.4.1 and it works without problems. On version 4.4.1 I tried to (1) add a parameter with reinstall, (2) add a second parameter and reinstall, (3) remove all params and reinstall and (4) finally add only one custom param with reinstall. All tests are ok on version 4.4.1 and the problem happens only on version 4.4.1.1. Please, have you some idea on how to solve the issue? Is this a bug? Thank you, Marco

Hello, I'm running 4.3.5.4-1.el7. I've exported a VM as OVA and now I'm trying to import it in another Data Center (it's like a DR Data Center) Import runs successfully both from GUI and from Ansible, but imported VM disks are empty and the VM fails to boot. How can I import disks content too? Thanks in advance for any help. Paolo

Hello Gianluca, thanks for opening the bug. I have also reported my test scenario below. (One thing more in my case, the standalone Manager needs to be installed on EL8 and not like documents says on EL7. With EL7 load is gives an error that Engine for EL7 is not avaiable. Document needs to be updated.) --- The same error occurs when trying to add a node to a standalone Engine Manager. Steps to Reproduce: 1. install a standalone Engine Manager on EL8 step by step with this documentation https://www.ovirt.org/documentation/installing_ovirt_as_a_standalone_manage… 2. install a node using ovirt-node-ng-installer-4.4.1-2020071311.el8.iso 3. try to add the node inside the Engine Manager Log output: 2020-07-21 10:14:17 CEST - included: /usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-host-deploy-vdsm/tasks/packages.yml for ovirtnode1.example.net 2020-07-21 10:14:17 CEST - included: /usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-host-deploy-vdsm/tasks/vdsmid.yml for ovirtnode1.example.net 2020-07-21 10:14:17 CEST - included: /usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-host-deploy-vdsm/tasks/pki.yml for ovirtnode1.example.net 2020-07-21 10:14:17 CEST - included: /usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-host-deploy-vdsm/tasks/restart_services.yml for ovirtnode1.example.net 2020-07-21 10:14:17 CEST - TASK [ovirt-host-deploy-vdsm : Install ovirt-host package] ********************* 2020-07-21 10:14:17 CEST - 2020-07-21 10:14:17 CEST - fatal: [ovirtnode1.example.net] FAILED! => {"changed": false, "module_stderr": "/bin/sh: /usr/bin/python2: No such file or directory\n", "module_stdout": "", "msg": "The module failed to execute correctly, you probably need to set the interpreter.\nSee stdout/stderr for the exact error", "rc": 127} 2020-07-21 10:14:17 CEST - { "status" : "OK", "msg" : "", "data" : { "uuid" : "bfb59a41-6672-4115-ba93-1755556b3d11", "counter" : 61, "stdout" : "fatal: [ovirtnode1.example.net] FAILED! => {\"changed\": false, \"module_stderr\": \"/bin/sh: /usr/bin/python2: No such file or directory\\n\", \"module_stdout\": \"\", \"msg\": \"The module failed to execute correctly, you probably need to set the interpreter.\\nSee stdout/stderr for the exact error\", \"rc\": 127}", "start_line" : 54, "end_line" : 55, "runner_ident" : "230c108e-cb2a-11ea-97da-00155d120809", "event" : "runner_on_failed", "pid" : 28965, "created" : "2020-07-21T08:14:16.528490", "parent_uuid" : "00155d12-0809-c845-9450-0000000001a1", "event_data" : { "playbook" : "ovirt-host-deploy.yml", "playbook_uuid" : "3a66c11c-02f9-492a-937d-21f1386e492d", "play" : "all", "play_uuid" : "00155d12-0809-c845-9450-000000000006", "play_pattern" : "all", "task" : "Install ovirt-host package", "task_uuid" : "00155d12-0809-c845-9450-0000000001a1", "task_action" : "yum", "task_args" : "", "task_path" : "/usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-host-deploy-vdsm/tasks/packages.yml:2", "role" : "ovirt-host-deploy-vdsm", "host" : "ovirtnode1.example.net", "remote_addr" : "ovirtnode1.example.net", "res" : { "module_stdout" : "", "module_stderr" : "/bin/sh: /usr/bin/python2: No such file or directory\n", "msg" : "The module failed to execute correctly, you probably need to set the interpreter.\nSee stdout/stderr for the exact error", "rc" : 127, "_ansible_no_log" : false, "changed" : false }, "start" : "2020-07-21T08:14:15.365609", "end" : "2020-07-21T08:14:16.528185", "duration" : 1.162576, "ignore_errors" : null, "event_loop" : null,a "uuid" : "bfb59a41-6672-4115-ba93-1755556b3d11" } }

ovirt 4.4 installation issues
by Markus Schaufler 21 Jul '20

21 Jul '20

Hi all, in our environment, CentOS7 and RHEL7 for the most part (Ovirt 4.3 and RHV 4.3), we are able to set a proxy directly in /etc/yum.conf (or on the single repo) to momentarily bypass some network restrictions. The proxy settings looks like this: proxy=http://our-proxy.domain:8080 proxy_username=user proxy_password=password But is also works properly when it is set directly from CLI, and this is the one we use more often: export http_proxy=http://user:password@our-proxy.domain:8080 export https_proxy=https://user:password@our-proxy.domain:8080 We are having difficulties to set the same proxy on CentOS8 / Ovirt 4.4.x. There is no way the proxy settings allows us to run "yum update". Extra Packages for Enterprise Linux 8 - x86_64 0.0 B/s | 0 B 00:00 Errors during downloading metadata for repository 'ovirt-4.4-epel': - Curl error (56): Failure when receiving data from the peer for https://mirrors.fedoraproject.org/metalink?repo=epel-8&arch=x86_64&infra=st… [Received HTTP code 407 from proxy after CONNECT] Error: Failed to download metadata for repo 'ovirt-4.4-epel': Cannot prepare internal mirrorlist: Curl error (56): Failure when receiving data from the peer for https://mirrors.fedoraproject.org/metalink?repo=epel-8&arch=x86_64&infra=st… [Received HTTP code 407 from proxy after CONNECT] Can somebody maybe point us to a solution? The above command is extracted by 'yum update' after a clean installation of Ovirt 4.4.1-2020070811 (but the same issue happened on previous versions and Nightly versions too). Thank you, Markus

Slow ova export performance
by francesco＠shellrent.com 20 Jul '20

20 Jul '20

Hi All, I'm facing a really slow export ov vms hosted on a single node cluster, in a local storage. The Vm disk is 600 GB and the effective usage is around 300 GB. I estimated that the following process would take up about 15 hours to end: vdsm 25338 25332 99 04:14 pts/0 07:40:09 qemu-img measure -O qcow2 /rhev/data-center/mnt/_data/6775c41c-7d67-451b-8beb-4fd086eade2e/images/a084fa36-0f93-45c2-a323-ea9ca2d16677/55b3eac5-05b2-4bae-be50-37cde7050697 A strace -p of the pid shows a slow progression to reach the effective size. lseek(11, 3056795648, SEEK_DATA) = 3056795648 lseek(11, 3056795648, SEEK_HOLE) = 13407092736 lseek(14, 128637468672, SEEK_DATA) = 128637468672 lseek(14, 128637468672, SEEK_HOLE) = 317708828672 lseek(14, 128646250496, SEEK_DATA) = 128646250496 lseek(14, 128646250496, SEEK_HOLE) = 317708828672 lseek(14, 128637730816, SEEK_DATA) = 128637730816 lseek(14, 128637730816, SEEK_HOLE) = 317708828672 lseek(14, 128646774784, SEEK_DATA) = 128646774784 lseek(14, 128646774784, SEEK_HOLE) = 317708828672 lseek(14, 128646709248, SEEK_DATA) = 128646709248 The process take a single full core, but i don't think this is the problem. The I/O is almost nothing. Any idea/suggestion? Thank you for your time Regards

Good morning, i have installed a new ovirt 4.3.10 enviroment but sometimes on the events of some hosts i read this error message: VDSM node-1-ra command Get Host Capabilities failed: Message timeout which can be caused by communication issues Due to this issue hosts are in unresponsive state and the only way to resolve this is and activate host in the cluster, is to restart the ovirt engine service. Can anyone help me? Thanks in advance Luigi

oVirt install questions
by David White 20 Jul '20

20 Jul '20

I'm reading through all of the documentation at https://ovirt.org/documentation/, and am a bit overwhelmed with all of the different options for installing oVirt. My particular use case is that I'm looking for a way to manage VMs on multiple physical servers from 1 interface, and be able to deploy new VMs (or delete VMs) as necessary. Ideally, it would be great if I could move a VM from 1 host to a different host as well, particularly in the event that 1 host becomes degraded (bad HDD, bad processor, etc...) I'm trying to figure out what the difference is between an oVirt Node and the oVirt Engine, and how the engine differs from the Manager. I get the feeling that `Engine` = `Manager`. Same thing. I further think I understand the Engine to be essentially synonymous with a vCenter VM for ESXi hosts. Is this correct? If so, then what's the difference between the `self-hosted` vs the `stand-alone` engines? oVirt Engine requirements look to be a minimum of 4GB RAM and 2CPUs. oVirt Nodes, on the other hand, require only 2GB RAM. Is this a requirement just for the physical host, or is that how much RAM that each oVirt node process requires? In other words, if I have a physical host with 12GB of physical RAM, will I only be able to allocate 10GB of that to guest VMs? How much of that should I dedicated to the oVirt node processes? Can you install the oVirt Engine as a VM onto an existing oVirt Node? And then connect that same node to the Engine, once the Engine is installed? Reading through the documentation, it also sounds like oVirt Engine and oVirt Node require different versions of RHEL or CentOS. I read that the Engine for oVirt 4.4.0 requires RHEL (or CentOS) 8.2, whereas each Node requires 7.x (although I'll plan to just use the oVirt Node ISO). I'm also wondering about storage. I don't really like the idea of using local storage, but a single NFS server would also be a single point of failure, and Gluster would be too expensive to deploy, so at this point, I'm leaning towards using local storage. Any advice or clarity would be greatly appreciated. Thanks, David Sent with ProtonMail Secure Email.

Info on transporting a gluster storage domain
by Gianluca Cecchi 19 Jul '20

19 Jul '20

Hello, I have env1 and env2, both in 4.3 and both configured as single host HCI environments. On both I have the predefined hosted_storage, data and vmstore gluster storage domains. On env1 I have hosted_storage and data on a disk, and vmstore on a whole different disk. I also have a "big2" gluster storage domain created in another disk in a second time. I want to scratch env1 but preserve and then import vmstore and big2 storage domains in env2 This "big2" is configured as a PV on the whole 4Tb disk on env1. - nvme1n1 4Tb gluster_vg_4t2 serial: BTLF72840DVK4P0DGN eui.01000000010000005cd2e45c02de4d51 dm-3 NVME,INTEL SSDPEDKX040T7 size=3.6T features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='service-time 0' prio=0 status=active `- 1:0:1:0 nvme1n1 259:3 active undef running [root@ovirt ~]# pvs /dev/mapper/eui.01000000010000005cd2e45c02de4d51 PV VG Fmt Attr PSize PFree /dev/mapper/eui.01000000010000005cd2e45c02de4d51 gluster_vg_4t2 lvm2 a-- <3.64t 0 [root@ovirt ~]# [root@ovirt ~]# lvs gluster_vg_4t2 LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert gluster_lv_big2 gluster_vg_4t2 Vwi-aot--- <4.35t my_pool 1.36 my_pool gluster_vg_4t2 twi-aot--- <3.61t 1.64 0.18 [root@ovirt ~]# In similar way the vmstore storage domain has: - nvme2n1 1Tb gluster_vg_nvme1n1 serial: PHLF8125037R1P0GGN eui.01000000010000005cd2e4e359284f51 dm-1 NVME,INTEL SSDPE2KX010T7 size=932G features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='service-time 0' prio=0 status=active `- 2:0:1:0 nvme2n1 259:2 active undef running [root@ovirt ~]# pvs /dev/mapper/eui.01000000010000005cd2e4e359284f51 PV VG Fmt Attr PSize PFree /dev/mapper/eui.01000000010000005cd2e4e359284f51 gluster_vg_nvme1n1 lvm2 a-- 931.51g 0 [root@ovirt ~]# [root@ovirt ~]# lvs gluster_vg_nvme1n1 LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert gluster_lv_vmstore gluster_vg_nvme1n1 Vwi-aot--- 930.00g gluster_thinpool_gluster_vg_nvme1n1 63.99 gluster_thinpool_gluster_vg_nvme1n1 gluster_vg_nvme1n1 twi-aot--- 921.51g 64.58 1.80 [root@ovirt ~]# I presume the correct way is: - env1 delete and detach vmstore and big2 (without formatting/zeroing) - env2 attach the two disks to the system and then? What should I do at gluster commands level to "import" the already setup gluster bricks/volumes and then at oVirt side to import the corresponding storage domain? BTW: can I import the previous storage domain named "vmstore" giving anothe r name such as vmstore2, not to create conflict with already existing "vmstore" storage domain or the name is hard coded when importing and creating possible conflict? Thanks, Gianluca

Strange SD problem

ovirt 4.4.1.1 hci and problems with ansible 2.9.10 and/or missing python2
by Gianluca Cecchi 17 Jul '20

17 Jul '20

Hello, today I wanted to test a single host hci install using ovirt-node-ng-installer-4.4.1-2020071311.el8.iso On this same environment 4.4.0 gui wizard worked ok, apart a final problem with cpu flags and final engine boot up, so I wanted to verify if all is ok now, because that problem should have been fixed But I incurred in the same problems recently discussed here: https://lists.ovirt.org/archives/list/users@ovirt.org/message/3AARZD4VBNNHW… The first part failed because of TASK [gluster.infra/roles/backend_setup : Change to Install lvm tools for RHEL systems.] *** fatal: [novirt2st.storage.local]: FAILED! => {"changed": false, "msg": "The Python 2 yum module is needed for this module. If you require Python 3 support use the `dnf` Ansible module instead."} To have the first stage work (now I have to continue with the "Continue to Hosted Engine Deployment" step) I have to modify: - /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/main.yml force to use dnf as package manager. For some reason not automatically detected by the "package" ansible module from - name: Change to Install lvm tools for RHEL systems. package: name: device-mapper-persistent-data state: present when: ansible_os_family == 'RedHat' to - name: Change to Install lvm tools for RHEL systems. package: name: device-mapper-persistent-data state: present use: dnf when: ansible_os_family == 'RedHat' - /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/vdo_create.yml change from yum to package and specify to use dnf from: - name: Install VDO dependencies #maybe use package module? yum: name: "{{ packages }}" register: vdo_deps ... to: - name: Install VDO dependencies #maybe use package module? package: name: "{{ packages }}" use: dnf register: vdo_deps ... So in my opinion a bug has to be opened if not already done. The root cause being or for any reason ansible 2.9.10 that recently updated 2.9.9 or having removed python2 modules from the distribution, that before was for some reason silently used with yum, while not using the expected dnf module with package.... I'm going to test if in the next phase any further modification has to be done. Gianluca

Deployment is only to three as JBOD, 1 drive per node per volume (engine, data, vmstore) utilizing VDO. Thus, deploying even a 100G volume to 1.6TB drive fails with "insufficient free space" error. I suspect this might have to do with the Ansible playbook deploying Gluster mishandling the logical volume creation due to the rounding error as described here: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/ht… If I can provide any additional information, logs, etc. please ask. Also, if anyone has experience/suggestions with Gluster config for hyperconverged setup on NVMe drives I would greatly appreciate any pearls of wisdom. Thank you so very much for any assistance!
