This is not the storage related problem and looks like a virt issue. According to Federico, possibly the problem is that selinux is on but libvirt does not load the selinux driver since it is disabled in the conf file. Please attach /etc/libvirt/qemu.conf to verify. If this is correct then this is due to a libvirt version that accidentally was released with this off by default and the solution would be to bump the conf version so that vdsm would reconfigure it upon startup (workaround is just to change this config and reload).

IIUC this is a setup issue addressed by http://gerrit.ovirt.org/#/c/19005/. Further details and debug logs can be found in bug 1006952
Interesting. Then why it is working in one direction and other one not? As I have same versions of components... Is there a workaround?
Verified in vdsm-4.13.0-0.2.beta1.el6ev.x86_64 (is18). VM migration finishes successfully, no errors in vdsm logs nor engine log.
