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?
It looks to me like that patch only supports migrating to a tcp://
socket, not what I was looking to do... but looking at the qemu driver's
implementation of save and restore, I should be able to use those
commands as they already exist.
My apologies for the noise.
