Hi Lin, 1. I don't think Xen was accepted as an organization for 2012 GSOC. See http://lists.xen.org/archives/html/xen-devel/2012-03/msg02080.html. 2. The PMU project description in the wiki is vague. I know HVM guests support virtualized PMU. Please check vpmu.c files in /hvm, /svm, and /vmx directories. You better ask mentors for details (maybe this is XCP specific?). -Wei > > Regards, > Lin Ming > > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xen.org > http://lists.xen.org/xen-devel >
