This cleanup makes sense, but it'd be great to take advantage of the
lookup helpers I introduced lately to decrease the complexity even more.

Ah yeah, you do that in 2/2. ACK in this case if you rebase this patch
on the current HEAD (and thus get rid of the first two hunks.

New subject: [libvirt] [PATCH 2/2] qemu: Convert some APIs to use qemuDomObjFromDomain
Many internal qemu APIs must find domain object from passed
virDomainPtr. And with function Peter's introduced, we can use it
instead of copying multiple lines among code.

Many internal qemu APIs must find domain object from passed
virDomainPtr. And with function Peter's introduced, we can use it
instead of copying multiple lines among code.

Thanks, I've rebased both patches. Seems like our git is changing so
fast that I need to pull every day not every two days :).
Morover, I'll hold pushing this till 24th - it's gonna be a small
Christmas gift to libvirt from me :)
