[Libvir] Stability of virsh / libvirt interfaces

[John Levon <levon movementarian org>]

This has probably been discussed before so apologies.

What is the current status of the interfaces, especially libvirt and
virsh? Are they guaranteed to be stable? Does this apply to every new
interface as soon as a release is done?

(I ask after noticing that virsh schedinfo can be used to *set*
parameters!)

thanks
