libvirt users - Oct 2015 - enable aes for guest

Hi,
How do I enable aes for guest VM? Host CPU supports aes (cat /proc/cpuinfo
has aes in its flags and virsh capabilities also displays aes as a
feature). When I add
<features> <aes/> </features>
to the xml file, I am unable to create the VM. It complains with the below
error:

virsh create /tmp/tmp.xml
error: Failed to create domain from /tmp/tmp.xml
error: internal error: unexpected feature aes

Best!

You need to set a CPU model (+ optional features)
