That will only help on clusterside.
Has anyone good ideas on how to prevent domUs that are stored on evms or
clvm from beeing started on multiple dom0s?
Setting some lock on an ldap-server, in files on a ocfs2-fs or running
through the dom0s via ssh and asking if the domU is running would be
my ideas.. is there something less errorprone?
