That's a known issue, to which we do not have a clean-cut solution.
However, since ovirt-3.4 [1], you can configure Vdsm to avoid writing
HWADDR in its ifcfg files, by setting

    hwaddr_in_ifcfg = never

in /etc/vdsm/vdsm.conf.

This can be safely done only if NetworkManager is turned off, or with
new versions of NetworkManager (/me thinks 0.9.9.1) that supports
"interface-name: unmanaged-spec".
