Moving SelfHosted Engine
by murat.celebi＠dbpro.com.tr 31 Aug '22

Hello We have got an Production ovirt installation with 1 datacenter and 2 clusters. Default Cluster has got 2 hosts in it. kvm01 and kvm02. PrimarySite cluster has got 2 hosts in it. kvm03 and kvm04 Our Self hosted engine is running on kvm01. We need to migrate the Selfhosted-engine to kvm03 or kvm04 since the hosts kvm01 and kvm02 hosts are going to be retired. Anyone has any idea how this can be accomplished?

Failed to delete snapshot (again)
by Giulio Casella 30 Aug '22

30 Aug '22

Hi folks, since some month I have an issue with snapshot removals (I have storware vprotect backup system, heavily using snapshots). After some time spent on a bugzilla (https://bugzilla.redhat.com/show_bug.cgi?id=1948599) we discovered that my issue is not depending on that bug :-( So they pointed me here again. Briefly: sometime snapshot removal fails, leaving snapshot in illegal state. Trying to remove again (via ovirt UI) keeps failing and doesn't solve. The only way to rebuild a consistent situation is live migrating affected disk to another storage domain; after moving the disk, snapshot is no more marked illegal and then I can remove it. You can imagine this is a bit tricky, specially for large disks. In my logs I can find: 2022-08-29 09:17:11,890+02 ERROR [org.ovirt.engine.core.bll.MergeStatusCommand] (EE-ManagedExecutorService-commandCoordinator-Thread-1) [0eced56f-689d-422b-b15c-20b824377b08] Failed to live merge.

Thank you in advance. Regards, gc

Ovirt 4.4.7, can't renew certificate of ovirt engine (certificates expired)
by vk＠itiviti.com 30 Aug '22

30 Aug '22

Hi Team, I'm looking for your help since I didn't find any clear documentation. Is there somewhere in ovirt website a clear documentation about how to renew the engine certificates located in /etc/pki/ovirt-engine/certs/ We have an engine GUI not working, showing error message "PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed". After checking, all the cert in /etc/pki/ovirt-engine/certs/ are expired. I didn't find a clear documentation on ovirt website, or even on redhat website (it was always about host but not the engine) Anyway I've read that the renew process can be done via "engine-setup --offline", but when I try it, it generates this error: --== PKI CONFIGURATION ==-- [ ERROR ] Failed to execute stage 'Environment customization': Unable to load certificate. See https://cryptography.io/en/latest/faq/#why-can-t-i-import-my-pem-file for more details. and in log file: File "/usr/lib64/python3.6/site-packages/cryptography/hazmat/backends/openssl/backend.py", line 1371, in load_pem_x509_certificate "Unable to load certificate. See https://cryptography.io/en/la" ValueError: Unable to load certificate.

See https://cryptography.io/en/latest/faq/#why-can-t-i-import-my-pem-file for more details. I've also tried the manual procedure (using /usr/share/ovirt-engine/bin/pki-enroll-pkcs12.sh) mentioned in https://users.ovirt.narkive.com/4ugjgicE/ovirt-regenerating-new-ssl-certifi… (message from Alon Bar-Lev), but the 4th command always says I enter a wrogn apssword, but it's not. we are blocked here and we can't use our ovirt cluster, so it's pretty blocking. Thx a lot in advance

unable to bring up gluster bricks after 4.5 upgrade
by Jayme 29 Aug '22

29 Aug '22

Hello All, I've been struggling with a few issues upgrading my 3-node HCI custer from 4.4 to 4.5. At present the self hosted engine VM is properly running oVirt 4.5 on CentOS 8x stream. First host node, I set in maintenance and installed new node-ng image. I ran into issue with rescue mode on boot which appears to have been related to LVM devices bug. I was able to work past that and get the node to boot. The node running 4.5.2 image is booting properly and gluster/lvm mounts etc all look good. I am able to activate the host and run VMs on it etc. however, oVirt cli is showing that all bricks on host are DOWN. I was unable to get the bricks back up even after doing a force start of the volumes. Here is the glusterd log from the host in question when I try force start on the engine volume (other volumes are similar: ==> glusterd.log <== The message "I [MSGID: 106568] [glusterd-svc-mgmt.c:266:glusterd_svc_stop] 0-management: bitd service is stopped" repeated 2 times between [2022-08-29 18:09:56.027147 +0000] and [2022-08-29 18:10:34.694144 +0000] [2022-08-29 18:10:34.695348 +0000] I [MSGID: 106618] [glusterd-svc-helper.c:909:glusterd_attach_svc] 0-glusterd: adding svc glustershd (volume=engine) to existing process with pid 2473 [2022-08-29 18:10:34.695669 +0000] I [MSGID: 106131] [glusterd-proc-mgmt.c:84:glusterd_proc_stop] 0-management: scrub already stopped [2022-08-29 18:10:34.695691 +0000] I [MSGID: 106568] [glusterd-svc-mgmt.c:266:glusterd_svc_stop] 0-management: scrub service is stopped [2022-08-29 18:10:34.695832 +0000] I [MSGID: 106617] [glusterd-svc-helper.c:698:glusterd_svc_attach_cbk] 0-management: svc glustershd of volume engine attached successfully to pid 2473 [2022-08-29 18:10:34.703718 +0000] E [MSGID: 106115] [glusterd-mgmt.c:119:gd_mgmt_v3_collate_errors] 0-management: Post commit failed on gluster2.xxxxx.

Please check log file for details. Post commit failed on gluster2.xxxx. Please check log file for details. I feel like this may be some issue with the difference in major versions of GlusterFS on the nodes but I am unsure. The other nodes are running ovirt-node-ng-4.4.6.3 At this point I am afraid to bring down any other node to attempt upgrading it without the bricks in UP status on the first host. I do not want to lose quorum and potentially disrupt running VMs. Any idea why I can't seem to start the volumes on the upgraded host? Thanks!

Commissioning hew host on centos9
by David Johnson 29 Aug '22

29 Aug '22

Good evening all, I am trying to commission an ovirt host on new hardware using Centos 9. I followed the pre-install instructions at https://www.ovirt.org/download/install_on_rhel.html, and eventually figured out that this line was missing from the preparation scripts: dnf install rdo-openvswitch-2.15 With that, I was able to continue installation. After completing the instructions, DNF update reports this: [root@localhost administrator]# dnf update --nobest Last metadata expiration check: 0:01:06 ago on Fri 26 Aug 2022 08:20:27 PM CDT.

oVirt 4.5 self-hosted network not working
by Paul-Erik Törrönen 25 Aug '22

25 Aug '22

Specifically, the installation (ovirt-hosted-engine-setup) completes successfully, and the engine VM is up and running, but it can not be accessed from any other machine in the same subnet but the host machine. I can ssh (from the host) to the engine VM, and confirm that initiating the connection from the engine VM to any other machine, except the host, fails. The routing looks correct and stopping the firewalld on the engine VM does not make any difference. Nor does stopping the firewalld on the host either make any difference. This seems like a failure in correctly setting up the host routing for the engine VM. How do I fix this? Poltsi

Ovirt 4.5.2 problem with change CD during VM installation
by Facundo Badaracco 25 Aug '22

25 Aug '22

HI everyone i have a GlusterGS replica 3 node. All is working fine. Except when i want to install a win10 x64 test VM. The windows ISO loads fine, when it comes the time to put de virio win so the VM recongnizes the disk, the change CD feature doesnt change anything. I have tried with several ISOs, but in the windows installer it never changes the CD, always seems empty. Any ideas? thx in advance.

oVirt Engine Dashboard and information from Guest Agents
by markeczzz＠gmail.com 25 Aug '22

25 Aug '22

Hi! Recently I had a situation where single node oVirt setup was without network connection to shared storage. After shared storage got reconnected, everything got up as it was supposed to, but I can't get information from guest agents shown in ovirt Dashboard. I tried restarting ovirt-engine and then 2 vm-s started sending info from guest-agent, but rest of them not. Guest agent is running on those vm-s. I also tried restarting those vm-s. Hosted engine is up and healty, and ovirt-engine service is running and it looks ok also. I have this error in vdsm.log 2022-08-25 10:41:39,913+0200 INFO (periodic/1) [vdsm.api] FINISH repoStats return={'dff59a93-4dca-40cd-9c44-c0a74ebaa656': {'code': 0, 'lastCheck': '2.2', 'delay': '0.000840686', 'valid': True, 'version': 5, 'acquired': True, 'actual': True}, '30c0c9e4-b634-4a05-b921-7a30b69f6dd2': {'code': 0, 'lastCheck': '3.9', 'delay': '0.000830941', 'valid': True, 'version': 5, 'acquired': True, 'actual': True}, '6cb12d96-3a0a-4902-acb0-deb907ef945c': {'code': 0, 'lastCheck': '5.5', 'delay': '0.000857244', 'valid': True, 'version': 5, 'acquired': True, 'actual': True}, '559569b9-c33e-4fb0-be6a-51a178a228a9': {'code': 0, 'lastCheck': '5.3', 'delay': '0.000463871', 'valid': True, 'version': 5, 'acquired': True, 'actual': True}} from=internal, task_id=8c638713-f010-4692-ba0b-1ac94052fe7c (api:54) 2022-08-25 10:41:40,778+0200 ERROR (qgapoller/2) [virt.periodic.Operation] <bound method QemuGuestAgentPoller._poller of <vdsm.virt.qemuguestagent.QemuGuestAgentPoller object at 0x7f9efc08e6d8>> operation failed (periodic:204) Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/vdsm/virt/periodic.py", line 202, in __call__ self._func() File "/usr/lib/python3.6/site-packages/vdsm/virt/qemuguestagent.py", line 493, in _poller vm_id, self._qga_call_get_vcpus(vm_obj)) File "/usr/lib/python3.6/site-packages/vdsm/virt/qemuguestagent.py", line 814, in _qga_call_get_vcpus if 'online' in vcpus: TypeError: argument of type 'NoneType' is not iterable 2022-08-25 10:41:41,551+0200 INFO (jsonrpc/2) [api.virt] START getStats() from=::1,50396, vmId=a6e745c4-2e4e-4672-8625-08b787832020 (api:48)

by Christoph Timm 24 Aug '22

24 Aug '22

Hi list, we have uploaded new ISO files to our data domain which we are using for ISO images and found out that we cannot boot from these ISO. Older ISOs are still working but no new one. I have not really any idea what to check and where to look so any kind of help would be really appreciated. Best regards Christoph
