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:

Trying to migrate to another Host (VM: testvm01, Source: ovirt-srv-02, Destination: ovirt-srv-03).

Both nodes run on CentOS 6.6 with the following versions:

OS Version: RHEL - 6 - 6.el6.centos.12.2

Kernel Version: 2.6.32 - 504.30.3.el6.x86_64

KVM Version: 0.12.1.2 - 2.448.el6_6.4

LIBVIRT Version: libvirt-0.10.2-46.el6_6.6

VDSM Version: vdsm-4.16.20-1.git3a90f62.el6

Any thoughts?

Thanks,

Sokratis
