Because it breaks other custom configuration (non-oVirt related).

I will probably try SELinux in enforcing mode when migrating to CentOS 7 hosts.

Is there any reason that you have SE Linux in permissive. oVirt will run with 
SE Linux in enforcing

I checked the vdsm.log and the source host was throwing this error:
libvirtError: unsupported configuration: Unable to find security driver for 
label selinux

I fixed it by disabling selinux (it was running in permissive mode before) and 
rebooting the host since selinux was also disabled on the other host.

Can you send the log from each node 
/var/log/vdsm/vdsm.log

Hi,

I'm having trouble migrating VMs in a 2-node cluster. VMs can start normally on 
both nodes if they are shutdown first but live migration fails and the 
following is thrown in the engine.log:

Any thoughts?

Thanks,
