The virDomainGetXMLDesc and virDomainGetInfo APIs for QEMU suffer from needing to run 'query-balloon' to update the balloon level. This has caused us performance problems and even worse caused us to lock up on a dead QEMU.
The following two patches to QEMU add a BALLOON_EVENT and a query-events command to QMP. With those two parts, we can avoiding running the query-balloon command at all. Thanks for re-posting these patches - but in the future, if you are going to take over someone else's patches it would be a good idea to contact
