[libvirt] [PATCH 1/9] conf: add info to virDomainStateReason

[Bjoern Walk]

On some architectures, QEMU exposes additional information on certain
domain states, e.g. for guest crashes. Let's add a field @info to the
virDomainStateReason struct inside virDomainObj which holds additional
state information.

One drawback is that this information is not serialized and is lost in
case of a daemon restart.
