[libvirt] [PATCH 0/2] Make non-KVM machines work with QMP probing

This "series wannabe" fixes a problem with SW emulated machines not
being able to be run with upstream qemu (no qemu-kvm + QMP probing).
Libvirt currently sets QEMU_CAPS_KVM based on the fact that QEMU knows
about 'query-kvm' QMP command.  This not necessarily means that
'-no-kvm' option needs to be supplied in order to disable KVM and that
consequently leads to a non-startable domain when qemu doesn't know
about the option.

In order to fix this issue only with QMP, I thought about two
possibilities, so...  The first patch represents what's identical for
both possibilities, whether the second one can be chosen from [2/2 v1]
and [2/2 v2] (I didn't come up with better naming, sorry).
