RE: [Xen-devel] Xen 4.1 rc5 outstanding bugs

["Zhang, Yang Z" <yang.z.zhang@xxxxxxxxx>]

I used rhel5u5 as guest and cannot reproduce this issue in my westmere-EP. Can 
you have a try with rhel5u5 guest?

Host: westmere-ep

Software:
Xen 4.1-rc6-pre
Pvops dom0: rhel5u5 with 2.6.32.27
Guest: rhel5u5

best regards
yang
