[one-users] Resume paused VM due to full system datastore

The recommended way is to recover the VMs manually and let the
monitorization process update the state in oned, as you describe in your
email. UNKNOWN state is to accommodate these failure situations (that may
require different recover procedures).

Note also that we can re-send from OpenNebula a deploy action (virsh
create, in your case) with onevm boot (or through the play icon in
Sunstone) for UNKNOWN, however there is no way to send from OpenNebula a
'virsh resume' command.

BTW OpenNebula 4.4 should control the system datastore usage (even not
shared) and not schedule VMs to prevent taking all the space, you can even
limit manually the size used by OpenNebula. Is this not working for you?
