* **Bug fixes**
* qemu: Fix disk quiescing rollback when creating external snapshots
If the qemu guest agent call to freeze filesystems failed when creating
an external snapshot with ``VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE`` flag the
filesystems would be unconditionally thawed. This could cause problems when
the filesystems were frozen by an explicit call to ``virDomainFSFreeze``
since the guest agent then rejects any further freeze attempts once are
filesystems frozen, an explicit freeze followed by a quiesced snapshot
would fail and thaw filesystems.
Users are also encouraged to use ``virDomainFSFreeze/Thaw`` manually instead
of relying on ``VIR_DOMAIN_SNAPSHOT_CREATE_QUIESCE`` if they need finer
grained control.
