[ClusterLabs] Antw: Re: kvm live migration, resource moving

Hi List,
I have two major problems related to the VirtualDomain live migration 
and failover in general.
I'm using Pacemaker 1.1.8, which is very stable and used to do 
everything right to me.

1. Live migration during failover (node standby or shutdown) is ok, but 
during failback, the VMs (which prefer the returning node) are trying to 
migrate too early and ignore the order/colocation constraints.

2. To be able to handle the internal VM shutdown, I have a libvirt hook, 
which simply does:
[ "${2}" = release ] && crm resource stop ${1}
The problem is that this hook always stops all the migrating/moving VMs 
in case of failover.

Any suggestions are welcome.

Thanks in advance,
