Adam Litke has uploaded a new change for review. Change subject: virt: Add a function to execute a qemu monitor command ...................................................................... virt: Add a function to execute a qemu monitor command Sometimes it is necessary to execute a monitor command directly (eg. if libvirt does not yet support a certain qemu feature). Libvirt will mark the VM as 'tainted' once this is done for the first time. The reason is that making modifications to a VM using this facility could cause a split-brain situation. It is generally harmless to execute monitor commands which act in a read-only fashion. This function is also useful as a utility for developers who are working on new features.
