RE: [Xen-devel] [PATCH 0/4] HVM Virtual S3 --- Revised and resent

["Ke, Liping" <liping.ke@xxxxxxxxx>]

Hi, Keir
It works fine, I test vcpu=1 or 2 on FC6_32p and FC8_32e
So no other problems I could see now -:). 
Thanks a lot!!
Regards,
Criping

Hopefully it is fixed by c/s 17730. I did not see this with a Fedora kernel,
perhaps because I tested a single-processor guest and perhaps that VCPU was
dropped into real mode before triggering S3. I'm not sure. Anyhow S3
definitely didn't work properly so I suspect there are still one or two bugs
which some wider testing coverage would pick out.
