[PVE-User] Moving disk to a new storage - VM Reboot

[Markos Vakondios]

Alexandre,

I think Kevin means that the VM (windows?) auto reboots itself sometimes
after live migration without knowing what triggers the reboot, correct?

What type of disk file do you use Kevin, raw/qcow2 and what disk cache
mode? Also, are there any VM snapshots on the migrated VMs?
