Description michal novacek 2016-09-20 12:38:17 UTC 
This is documentation bug.

Documentation for live-migration of the nodes in the pacemaker cluster is close
to non-existant not only on our (redhat) pages but altogether everywhere. 

The problem you would have trouble find documentation for:

  * how do I set-up live migration of virtual domains in the cluster
  * how do I test that it works
  * how do I setup pacemaker resource agent VirtualDomain to allow
     live migration of the guest?

I believe at least third option should be documented in our knowledgebase along
with the fact that live migration of virtual domains that are remote node in
the cluster is not supported.
Comment 1 Oyvind Albrigtsen 2016-09-20 13:40:37 UTC 
It requires allow-migrate=true, and setting SSH as transport makes it easier to setup (instead of SSL certificates):
# pcs resource create VM VirtualDomain config=/etc/libvirt/qemu/vm.xml migration_transport=ssh meta allow-migrate=true
