Testing oVirt backup and Restore operations 4.3
by Mikhail Po
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
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

GLPI agent on oVirt node 4.5.3.2

I try to install GLPI agent 1.5 (same result with 1.4) from [https://github.com/glpi-project/glpi-agent/releases] on oVirt 4.5 nodes. I get this error:

(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
I can't install the perl modules via dnf install on theses node. I guess is due to the restricted repost :
