In XO if we have a VM that for some reason as stopped/shutdown and the VM have a iso in the cdrom that is in a nfs library, when try to start the VM we get an error about wrong state.. as closed and should be started... and the VM won't start.
If we open xcp-ng center and try to start the VM it says the exists a mounted iso that is no longer avaiable and if we pretend eject before start, doing that the VM start without issue.
PS: I get into this because a power failure
