Speaking of this, I've noticed that <domain type='qemu'> <os> <type arch='i686' machine='pc'>hvm</type> </os> </domain> runs WITH kvm on an x86_64 system. Is that intended?

It seems that this comment in qemu_conf.c: /* Need to explicitly disable KVM if * 1. Arch matches host arch * 2. Guest domain is 'qemu' * 3. The qemu binary has the -no-kvm flag */ might need to expand #1 to consider i686 == x86_64?
