That would be incredibly useful when trying to triage bugs. Ubuntu
users often file virtualization bugs against virt-manager or virsh, in
that that's the interface they're using when they see a problem. And
it's up to me to figure out where in the virt-manager -> libvirt ->
qemu-kvm -> qemu stack the bug actually exists. The ability to
precisely run just the libvirt command line (without hand modification
like I have to do now) would be magical.
