Hi, all,

As I'm doing some research in cooperative scheduling between Xen and
guest domain, I want to know how many ways can Xen trigger a context
switch inside an HVM guest domain (which runs Windows in my case). Do
I have to write a driver (like balloon-driver)? Or a user process is
enough? Or there is an even simpler way?

All your suggestions are appreciated. Thanks! :)
