[CentOS] No live migration for xen virtual machines any more

  Hi folks,

I have upgraded my CentOS RHCS cluster hosts to the recent packages, and 
now live migration of the xen virtual machines does not work any more:

[root at node ~]# clusvcadm -M vm:XenVM -m othernode
Trying to migrate vm:XenVM to othernode...Invalid operation for resource

I have googled the net but found no recent entries for that problem, 
just older posts.

Has anyone had the same problem recently? If yes: is there any workaround?

Any hint or help is appreciated.

Dirk
