[Xen-users] [Question] How can I know CPU ring information?

[Andrew Son <mailing.son@xxxxxxxxx>]

Hi all,

In a para-virtualization, 32bit guest OS runs in ring 1, and
hypervisor runs in ring 0.

My question is that:

  1) Does guest OS know that my kernel run in ring 1?
  2) If so, does hypervisor inform this when guest OS boot?
  3) and, where is the ring information, or cpu register?

Thanks,

Choonho Son
