[libvirt] [PATCH 3/3] Convert QEMU driver to use virLogProbablyLogMessage

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

The current QEMU code for skipping log messages only skips over
'debug' message, switch to virLogProbablyLogMessage to make sure
it skips over all of them
