Re: [libvirt] [PATCHv2 00/14] Fix vmdef usage after ExitMonitor

Patches 3-8 fix possible crash/invalid memory access if QEMU crashes while we're in the monitor. Patches 9-13 change all other callers of qemuDomainObjExitMonitor to exit early in that case, but should not fix any real issues. They are necessary to turn on ATTRIBUTE_RETURN_CHECK for the ExitMonitor call.
