[libvirt] libvirt commands during migration

[Dan Kenigsberg <danken redhat com>]

Hi,

We've noticed that most of libvirt domain-specific calls block while
qemu is migrating.

Isn't it kind-of-a-bug? Migration can take a while; qemu allows to do it
in the background, and accepts monitor commands. So why should a libvirt
user be blocked from his favorite domblkstat?

Regards,

Dan.
