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?).
