Thanks, I have created a hook script which is available here: <a href="http://admin-reminder.blogspot.co.uk/2015/06/set-cpu-family-for-specific-vm-on-ovirt.html" target="_blank">
http://admin-reminder.blogspot.co.uk/2015/06/set-cpu-family-for-specific-vm-on-ovirt.html</a> if anyone would like to make use of it.<br>
