Adam Litke has submitted this change and it was merged. Change subject: guest monitor: split monitor from thread ...................................................................... guest monitor: split monitor from thread We have the GuestMonitor class which inherits from threading.Thread, and takes care of the per-VM monitor book-keeping and of the monitoring loop. This patch splits the class in two, with an explicit monitoring thread, decoupling the two responsabilities. This is needed for better scalability, because this way we can now optionally demand the actual invocation of the monitoring code to the hypervisor, which can integrate it with its monitoring loop(s). Moreover, this patch also adds explicit registration and deregistration methods for Guest Monitor objects inside the Guest Manager. Besides a little cleanup, this patch makes room for a future patch want to optionally demand the collection of the MOM stats to hypervisor. The old behaviour is preserved through fallback code.
