At least this is true for qemu while using sVirt. But you mentioned LXC, where sVirt is just now barely being added; so maybe the answer is to wait for the 0.9.10 release, and then ask the question again. -- Eric Blake eblake@xxxxxxxxxx +1-919-301-3266 Libvirt virtualization library http://libvirt.org
