[libvirt] [PATCH v2 0/4] Add support for QEMU guest agent control

==== These patches are taken from here: https://www.redhat.com/archives/libvir-list/2011-October/msg00135.html I've just rebased and polished them. ==== The QEMU guest agent "/usr/bin/qemu-ga" has some handy functions for controlling the guest, not least, shutdown/reboot and filesystem freeze/thaw. In Fedora 15/16 the semantics of the ACPI power button have been changed to suspend-to-RAM which breaks our current shutdown implementation. By adding support for the agent we gain a more predictable way to shutdown / reboot guests. NB: the code currently has the same "flaw" as the monitor, in so much as we wait forever for a guest agent reply. We need to add a timeout ability to the agent code diff to v1: - Eric's review taken in Daniel P.
