oVirt 4.4.7 development
by Michal Skrivanek 05 May '21

05 May '21

Hi all, we are starting to work on oVirt 4.4.7 and as you probably noticed we are slowly transitioning away from CentOS. We added CentOS Stream option for regular hosts, and the current 4.4.6 Node and Appliance are already built from Stream. We also have some initial patches for alternative RHEL clones other than CentOS, however we can’t really support them until they provide the required dependencies. We are not ditching CentOS just yet, but we can no longer accommodate the long delay it takes CentOS team to produce a next minor version, hence for oVirt 4.4.7 we will require the operating system to be at the RHEL 8.4 level - that’s a CentOS 8.4 if that gets released in time or the actual RHEL 8.4 or any 8.4 clone like Alma, Rocky, OL with the right dependencies (probably the ones from Stream) or CentOS Stream. In the meantime we're going to be moving the existing CI resources to test with CentOS Stream to unblock development of new features. If you would want to help with testing other OSes patches are welcome to add support for them Thanks, michal

Re: Unable to migrate Engine to another HE Host

Ok – These are the symlinks in place: 1. /var/run/vdsm/storage/<hosted_storage_id>/<path_to_conf_image> 2. /var/run/vdsm/storage/<hosted_storage_id>/<path_to_metadata_image> 3. /var/run/vdsm/storage/<hosted_storage_id>/<path_to_lockspace_image> 4. /var/run/vdsm/storage/<hosted_storage_id>/<path_to_vmdisk_id_image> - this one exist only on the current Host 5. /var/run/vdsm/storage/<hosted_storage_id>/<one more_link_I_have_no_clue what_it_is_for> Migration issue – seem to be solved at part 3: Part1: * Try to migrate HE from Host1 to Host3 – migration fails * Analysis showed that Host3 was missing the symlink num4 – which should be created during migration * I created symlink num4 and that migration works but HE on donor host has status “down_unexpected” instead of “down” Part2: * Next thing I noticed was that symlink num1 was missing on both Hosts * Added symlink num1 to both Hosts and reran the migration * Migration done successfully from Host1 to Host3 and HE on donor host had status “down” Part3: * Migrating back from Host3 to Host1 * Noticed that at beginning of migration the symlink num4 gets created on destination Host (Host1 in this case) * This time the symlink num4 on destination was not deleted and migration went through Part4: * Repeated migration from Host1 to Host3 * All went as expected. New HE Host deploy issue: * Current conclusion is that the new HE Host deploy was failing as the symlink num1 was not existing on running Hosts ( 1 and 3) so it was reported as missing/non-existent * Since the link is now added and it persists – I will try to deploy new HA Host I will keep you posted. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

How to use Ovirt node 4.4.5.0 with local storage
by danilosevilla＠gmail.com 04 May '21

04 May '21

Hi, I'm totally new with Ovirt. I have a production server in which I planned to install Ovirt. I need to use their local storage for Virtualization, but it seems that only have chance to storage in NAS or other network or fiber storage. Can I use the local storage for virtualization?. If yes, how can I do that. Thanks.

Hi, First of all, thanks for this great list and the people who try to help eachother. This time my problem is about engine OVF file or engine storage setting. How can i came with this idea, because every 2-3 hours engine try to migrate other host(From host1 to host2) "Invalid status on Data Center B300. Setting status to Non Responsive." when i check hosts log , see these ovirt-ha-agent ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine.config.vm ERROR Failed extracting VM OVF from the OVF_STORE volume, falling back to initial vm.conf ovirt-ha-agent ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine ERROR Engine VM stopped on localhost ovirt-ha-agent ovirt_hosted_engine_ha.lib.ovf.ovf_store.OVFStore ERROR Unable to extract HEVM OVF i believe there is some kind of fc storage path or config problem. My storage setting is good. there is no error about them Is there anyone who experienced about that to solve it thanks

Re: Unable to migrate Engine to another HE Host
by Marko Vrgotic 03 May '21

03 May '21

Investigation so far has showed, that symlink for conf_volume/conf_image is missing on Hosts 1 and 3. According to the ovirt-engine deep dive, connection/access to conf_volume is required for adding new HE Hosts as it holds its configuration template. This is most likely the reason why I could not add new Host and why the Host1 and Host3 were occasionally complaining the the conf_image_uuid is missing. I also checked the DB tb images – the conf_image and conf_volume entries exist. Question: Considering DB entries seem correct, am I “safe” to manually create the symlink on Host1 and Host3 , from global maintenance mode, set correct permissions and than exit maintenance mode? ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

'engine-cleanup' is a utility you run on the engine machine, which does basically the opposite of 'engine-setup', and in any case cleans up the _engine_, not any particular host. If you run it, your engine is gone, likely forever (unless you kept backups). What you might were looking for is 'ovirt-hosted-engine-cleanup'. This one cleans up a host from a hosted-engine deployment. It's generally intended to be used after a failed deployment attempt.

Re: Unable to migrate Engine to another HE Host

Dear Strahil and Yedidyah, Is it possible that HostedEngine DEPLOY on Host2 is failing due to “inability” to access the conf_volume_UUID “c518f937-60fe-4fed-a54c-db11328bb507” I do not see that error message on Host2, but I see it on Host1 and Host3: 2021-05-03 02:43:32,438-0700 ERROR (jsonrpc/5) [storage.TaskManager.Task] (Task='b4bba796-b62b-41cb-8d91-6637c5fb9705') Unexpected error (task:875) 2021-05-03 02:43:32,439-0700 ERROR (jsonrpc/5) [storage.Dispatcher] FINISH prepareImage error=Volume does not exist: (u'c518f937-60fe-4fed-a54c-db11328bb507',) (dispatcher:83) Could this be result of hosted-engine.conf staying empty and deployment not working? If I check the /var/log/ovirt-hosted-engine-setup/ folder is empty. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

'engine-cleanup' is a utility you run on the engine machine, which does basically the opposite of 'engine-setup', and in any case cleans up the _engine_, not any particular host. If you run it, your engine is gone, likely forever (unless you kept backups). What you might were looking for is 'ovirt-hosted-engine-cleanup'. This one cleans up a host from a hosted-engine deployment. It's generally intended to be used after a failed deployment attempt. I think it can work well also in your case, but would first try to fix using other means. > > If you fail to add host2 , you can always reinstall it as host4 and try to add it fresh. > > Best Regards, > Strahil Nikolov > > On Fri, Apr 30, 2021 at 16:27, Marko Vrgotic > <M.Vrgotic(a)activevideo.com> wrote: > > Dear oVirt, > > > > I have already reached out twice regarding the issues that occurred, due to power outage, but noticed only when upgrading engine to latest 4.3. version. > > > > I am unable to redeploy engine on Host2, the hosted-engine file stays empty and VDSM on Hosts1 and 3 is reporting, even though I cleared the metadata for the Host2, on Host 1 and Host3: > > > > 2021-04-30 05:57:58,454-0700 ERROR (jsonrpc/7) [ovirt_hosted_engine_ha.client.client.HAClient] Malformed metadata for host 2: received 0 of 512 expected bytes (client:137) > > > > Today I tried to migrate HE from Host 3 to Host 1 and it fails each time with following message: > > > > On Engine: > > 2021-04-30 12:57:56,961Z ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engine-Thread-1233892) [] EVENT_ID: VM_MIGRATION_TO_SERVER_FAILED(120), Migration failed (VM: HostedEngine, Source: ovirt-sj-03.ictv.com, Destination: ovirt-sj-01.ictv.com) > > > > On source Host: > > 2021-04-30 05:57:56,705-0700 ERROR (migsrc/66b6d489) [virt.vm] (vmId='66b6d489-ceb8-486a-951a-355e21f13627') Failed to migrate (migration:450) > > Traceback (most recent call last): > > File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 431, in _regular_run > > time.time(), migrationParams, machineParams > > File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 505, in _startUnderlyingMigration > > self._perform_with_conv_schedule(duri, muri) > > File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 591, in _perform_with_conv_schedule > > self._perform_migration(duri, muri) > > File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 525, in _perform_migration > > self._migration_flags) > > File "/usr/lib/python2.7/site-packages/vdsm/virt/virdomain.py", line 100, in f > > ret = attr(*args, **kwargs) > > 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 1781, in migrateToURI3 > > if ret == -1: raise libvirtError ('virDomainMigrateToURI3() failed', dom=self) > > libvirtError: operation aborted: migration out job: canceled by client > > > > > > I know that this version is end of life – but I would very much appreciate if someone could help me asses if this means corruption in DB or the overall damage, simply to know how to plan further actions. > > My impression was that I still had to functional HE Hosts in the pool, but after seeing migration failure, it’s pretty much down to single host. > > > > This is production system, so I cannot just move on to upgrading/deploying to 4.4. > > > > Additionally – : > > Is the effect of the engine-cleanup on HE Host local or it affects all HE Hosts?

Cluster level 4.5
by Don Dupuis 03 May '21

03 May '21

What version of libvirt is required for a host to be put in this cluster level? I am using CentOS 8.3 and cpu is Cascade Lake Server. It says that my host is only compatible with cluster version 4.2,4.3 and 4.4. I am doing a new install of Ovirt 4.4.5. I have tried to update libvirt version but have run into issues. Currently installed libvirt is libvirt-6.0.0-28.module_el8.3.0+555+a55c8938.x86_64. Don

'engine-cleanup' is a utility you run on the engine machine, which does basically the opposite of 'engine-setup', and in any case cleans up the _engine_, not any particular host. If you run it, your engine is gone, likely forever (unless you kept backups). What you might were looking for is 'ovirt-hosted-engine-cleanup'. This one cleans up a host from a hosted-engine deployment. It's generally intended to be used after a failed deployment attempt. I think it can work well also in your case, but would first try to fix using other means. > > If you fail to add host2 , you can always reinstall it as host4 and try to add it fresh. > > Best Regards, > Strahil Nikolov > > On Fri, Apr 30, 2021 at 16:27, Marko Vrgotic > <M.Vrgotic(a)activevideo.com> wrote: > > Dear oVirt, > > > > I have already reached out twice regarding the issues that occurred, due to power outage, but noticed only when upgrading engine to latest 4.3. version. > > > > I am unable to redeploy engine on Host2, the hosted-engine file stays empty and VDSM on Hosts1 and 3 is reporting, even though I cleared the metadata for the Host2, on Host 1 and Host3: > > > > 2021-04-30 05:57:58,454-0700 ERROR (jsonrpc/7) [ovirt_hosted_engine_ha.client.client.HAClient] Malformed metadata for host 2: received 0 of 512 expected bytes (client:137) > > > > Today I tried to migrate HE from Host 3 to Host 1 and it fails each time with following message: > > > > On Engine: > > 2021-04-30 12:57:56,961Z ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedThreadFactory-engine-Thread-1233892) [] EVENT_ID: VM_MIGRATION_TO_SERVER_FAILED(120), Migration failed (VM: HostedEngine, Source: ovirt-sj-03.ictv.com, Destination: ovirt-sj-01.ictv.com) > > > > On source Host: > > 2021-04-30 05:57:56,705-0700 ERROR (migsrc/66b6d489) [virt.vm] (vmId='66b6d489-ceb8-486a-951a-355e21f13627') Failed to migrate (migration:450) > > Traceback (most recent call last): > > File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 431, in _regular_run > > time.time(), migrationParams, machineParams > > File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 505, in _startUnderlyingMigration > > self._perform_with_conv_schedule(duri, muri) > > File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 591, in _perform_with_conv_schedule > > self._perform_migration(duri, muri) > > File "/usr/lib/python2.7/site-packages/vdsm/virt/migration.py", line 525, in _perform_migration > > self._migration_flags) > > File "/usr/lib/python2.7/site-packages/vdsm/virt/virdomain.py", line 100, in f > > ret = attr(*args, **kwargs) > > 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 1781, in migrateToURI3 > > if ret == -1: raise libvirtError ('virDomainMigrateToURI3() failed', dom=self) > > libvirtError: operation aborted: migration out job: canceled by client > > > > > > I know that this version is end of life – but I would very much appreciate if someone could help me asses if this means corruption in DB or the overall damage, simply to know how to plan further actions. > > My impression was that I still had to functional HE Hosts in the pool, but after seeing migration failure, it’s pretty much down to single host. > > > > This is production system, so I cannot just move on to upgrading/deploying to 4.4. > > > > Additionally – : > > Is the effect of the engine-cleanup on HE Host local or it affects all HE Hosts?
