I'm looking at building a framework which makes use of KVM's pseudo-migration support for snapshot management. To my knowledge, this functionality is not presently available through libvirt. Is it possible to send arbitrary qemu/kvm admin console commands to a VM started and controlled by libvirt, or does any requirement for funtionality not presently exposed through libvirt conflict with its use?

We'd really like you to send commands via libvirt. Which commands in particular do you want to send? I have an outstanding patch [1] to support KVM migration which just needs much more testing. Perhaps it does what you need already?
