Hi, Mike

 Then I have a question.
 When your scheduler patch effects performance improvement?
(like improvement of various latency for Driver Domain etc.)

Sakai,
After these first patches get accepted I plan on implementing a
feature where one domain can tell the scheduler it would like to run
*after* a different domain in the same group.
Xen already does this for dom0, but we also think it will improve
performance for hvm domains when they use a stub domain for device
emulation.
