Dear team,
We had implemented CBT support for RHV and oVirt in our new version, but when testing we encountered problems of obtain VM increments and also had abnormal with the VM virtual disks.
Our testing environment as below: OS Version: RHEL - 8.4.2105.0 - 3.el8 OS Description: oVirt Node 4.4.7 Kernel Version: 4.18.0 - 315.el8.x86_64 KVM Version: 6.0.0 - 19.el8s LIBVIRT Version: libvirt-7.4.0-1.el8s VDSM Version: vdsm-4.40.70.6-1.el8
One of the problem is after a successful backup, the VM which gets only one virtual disk will get 2 identical virtual disks marked as Complete on oVirt engine web console, like shown below.
The additional disk might disappear after a while, but before it’s gone there could be a lot of problems with the VM.
1. We cannot perform a new backup, the backup will fail directly.
2. The VM itself will run into exception, we cannot even power it off, and it will also probably get crashed.
3. If the VM was initially powered off, after backing up, we cannot power on the VM.
And there could be some other problems related with this, is this normal or there’s something we did wrong?
Thank you in advance for your help!
