Bug when move VM from storage snapshot-able (ZFS) to storage not snapshot-able

[dea]

Hi !

Case:

1) VM in node 1 on ZFS storage: create snapshot
2) VM in node 1 migrate storage to datastore LVM (iscsi)
3) Old snapshot is visible (???) but inconsistent.
4) VM with cdrom ISO set before snapshot now set to "none"
5) Migrate VM to node 2: unable to migrate because is set an ISO (not true)
6) VM.conf is heavily uncleaned, ISO is set in an old snapshot, but snapshot is related to an old state (inconsistent)

OK, if I modify .conf cleaning the inconsistent state all works.

Would be needed more controls to lock inconsistent states....
