I have a question about xen. I want to do the following operation:
When a domU enters the hypervisor (e.g. error handling, or other ways
to enter the hypervisor), the domU suspends itself.
Then the dom0 can resumes the domU which was suspended.

I find that domain_pause() does not allow a domain to suspend itself. So I tried
vcpu_sleep_sync(), vcpu_sleep_nosync(), or vcpu_force_reschedule()
within the context of the domU in the hypervisor code. But none of
them works. The domain continues its execution.

I am working on xen-3.3.1 for my legacy purposes. The domU is a PV (not hvm).

How can I suspend a domU from within the domU itself? I look forward
to your help.

thanks,,
long
