Subject: [PATCH] qemuCheckpointCreateXML: Check VM liveness first
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move the liveness check prior to the capability check. If the VM is
offline the capabilities are not initialized and thus we'd report the
wrong error.
