[libvirt] [PATCH 1/5] Store max migration bandwidth in qemuDomainObjPrivate struct
From: Jim Fehlig <jfehlig(a)novell.com>
The maximum bandwidth that can be consumed when migrating a domain
is better classified as an operational vs configuration parameter of
the dommain. As such, store this parameter in qemuDomainObjPrivate
structure.
