Hello everyone, This is a newbie question, please ignore the ignorance. :) Is there a way i can get a list of all guest pages dirtied in a given time-period? I know that the live-migration mechanism uses this info.. I came across this thread : http://www.kerneltrap.com/mailarchive/linux-kvm/2009/6/11/5943303 which mentions using the dirty info in KSM. This is precisely what i wish to do. I've observed that KSM spends too much time mem_cmp'ing pages, and if there was a way to feed it a list of dirty guest pages, there would be signficant speedup.
So my question is: Is there a 'safe' way to get the dirty pages list? Are the overheads mentioned in the link above still relevant ? Thanks. -- Prateek -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
