Testing oVirt backup and Restore operations 4.3
by Mikhail Po 07 Sep '23

07 Sep '23

There was a desire to conduct a test backup and restore operation ovirt-node-ng 4.3.2-2019031908 Operations performed: - Deployed two test hosts, configured Hosted Engine. Created two test VMs. - Created a backup copy # engine-backup --mode=backup --file=ovirt-full-backup_2023-09-04.tar --log=ovirt-full-backup_2023-09-04.log - Turned off the original Self-hosted Engine and disconnected from Self-hosted Domain Storage # hosted-engine --vm-shutdown # hosted-engine --disconnect-storage - Created a new host using a previously created backup # hosted-engine --deploy --restore-from-file=ovirt-full-backup_2023-09-04.tar Although an error occurred at the end of the installation (after the start of copying to the iSCSI shared storage), but oVirt is accessible via the Web. The error that occurred [ INFO ] TASK [ovirt.hosted_engine_setup : Check for the local bootstrap VM] [ ERROR ] Error: The response content type 'text/html; charset=iso-8859-1' isn't the expected XML [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The response content type 'text/html; charset=iso-8859-1' isn't the expected XML"} [ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook ... [ INFO ] Stage: Clean up [ INFO ] Cleaning temporary resources [ ERROR ] Hosted Engine deployment failed: please check the logs for the issue, fix accordingly or re-deploy from scratch. Log file is located at /var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-20230907201859-ovmmky.log In the Web interface - all Hosts are green - all VMs are green. There is a virtual machine "external-HostedEngineLocal". - Storage Domain "hosted_storage_old_20230907T202958" is present. Any questions: 1. The instructions say that at the end you need to reinstall the hosts. Is it necessary to do this? I ask, because in my case, all hosts are available to the manager, virtual machines are working. What is this operation necessary for? 2. What to do with the "external-HostedEngineLocal" virtual machine? 3. Why the "Error" error occurred: The response content type 'text/html; charset=iso-8859-1' isn't the expected XML"? Can it be related to the lack of access to the Internet (repository) have a VM Engine? When installing hosts, access to the Internet is required (otherwise the installation does not occur), I register access through a proxy in yum.conf

oVirt 4.5.4-1 OVA export generates incomplete XML tag in vm.ovf
by lars.stolpe＠bvg.de 07 Sep '23

07 Sep '23

Hi, we can't import some OVA VMs into oVirt, that was previously exported in oVirt. Further investigations and testing showed, that in some vm.ovf files the last closing tag is missing ( </ovf:Envelope instead of </ovf:Envelope> ). Intense testing showed the following occurrence: on test DC (4.4.10.7-1): - about half of the VMs have that problem (about 9 VMs) - VMs where the export is working properly are ok, no matter how often i do export - VMs who's vm.ovf is wrong stay that way, no matter how often i do export on production DC (4.4.10.7-1): - all VMs have that problem (49 VMs) - an imported "good" VM formerly exported on test DC, now have a wrong vm.ovf too after re-exporting on production DC - vm.ovf of all VMs stay incorrect, no matter how often i do export on develop DC (4.5.4-1): - the only VM have that problem (1 VM) - vm.ovf of VMs stay incorrect, no matter how often i do export Environment: all DC have independent hardware and are built exactly the same way with the same components oVirt is with hosted-engine test and production: oVirt: 4.4.10.7-1 engine OS: Cent OS Stream 8 host OS: RHEL 8.7 develop: oVirt: 4.5.4-1 engine OS: Cent OS Stream 8 (latest updates till September 1st) host OS: RHEL 8.8 (latest updates till September 1st) Is that a known problem? Is there a way to fix this? regards, Lars

I login web interface using IP with Internal Server Error
by javin158＠163.com 31 Aug '23

31 Aug '23

Hi, I’m using ovirt version 4.5.4, and I want to log in to the web interface using an IP address. After modifying the field SSO_ALTERNATE_ENGINE_FQDNS in the configuration file /etc/ovirt-engine/engine.conf.d/11-setup-sso.conf to an IP address, I was able to open the URL https://172.20.52.245/ovirt-engine/. However, when I tried to log in as a user, I encountered the following error: " Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator at root@localhost to inform them of the time this error occurred, and the actions you performed just before this error. More information about this error may be available in the server error log. " I got error message from file /var/log/httpd/ssl_error_log: " [Wed Aug 30 10:42:48.825547 2023] [auth_openidc:error] [pid 64405:tid 139916067432192] [client 172.20.50.110:60017] oidc_authenticate_user: the URL hostname (ovirt-engine-01.labl.local) of the configured OIDCRedirectURI does not match the URL hostname of the URL being accessed (172.20.52.245): the "state" and " session" cookies will not be shared between the two!, referer: https://172.20.52.245/ovirt-engine/" Can you please point me in some direction to try to fix this? Thanks, and best regards cph

Re: Separate NFS Domain Storage for each Domain Storage
by Mikhail Po 30 Aug '23

30 Aug '23

For the initial installation of the operating system in a virtual machine, you need to mount an ISO image that is located in the storage domain of the NFS type (ISO function). If the NFS server is located within a high-speed LAN (one data center), then there are no problems, if you need to connect an image to a remote site (second data center) with slow channels, then difficulties arise.

Separate NFS Domain Storage for each Domain Storage
by Mikhail Po 28 Aug '23

28 Aug '23

Is it possible in oVirt 4.3 for each Data Center to create a separate ISO Domain Storage, with NFS type, on one of the hosts belonging to this Data Center? For example, in the case of connecting a remote site in a separate Data Center to an existing Engine through slow network links.
