[ovirt-users] Re: Tasks stuck waiting on another after failed storage migration (yet not visible on SPM)
Sorry for the late reply, but you may have hit this bug[1], I forgot about it.
The bug happens when you live migrate a VM in post-copy mode, vdsm
stops monitoring the VM's jobs.
The root cause is an issue in libvirt, so it depends on which libvirt
version you have

Hello,
I tried the live migrate as well and it didn't help (it failed).
The VM disks were in a illegal state so I ended up restoring the VM from backup (It was
least complex solution for my case).
Thank you both for the help.
Regards,
