[Openstack] CPU Flags with KVM/OpenStack

I've got a working installation of OpenStack Icehouse running on CentOS
6.5, works great. However, one of my image types, a FreeBSD 10.0 image,
is not playing well with a CPU flag and KVM on my compute nodes. What I
need to do is disable a CPU feature in the KVM libvirt.xml files on the
compute node, or rather, have OpenStack Nova do that for me when I
launch the FreeBSD image specifically. Is there any way I can easily do
that? I'm needing to disable the xsave feature for Intel processors, if
that makes any difference. But I suspect the solution would be more
generic, like, "do this to tweak xml on image deployment" or something...?
Any hints greatly appreciated!!
