libguestfs wants "best effort" behaviour, and libvirt wants "KVM or die"
behaviour.
For what it's worth, default gives you exactly that with qemu-kvm.
Maybe that's good enough, on the theory that if you have KVM, you most
likely have libguestfs using qemu-kvm.
Avi, can you comment on whether just opening /dev/kvm O_RDWR is a
reasonable way to detect if KVM is available?
Markus, any idea when we might get the -accel option appearing in
released versions of qemu/KVM?
No idea. Anthony?
I see no problem with 0.15 if someone cooks up a patch.
