Keir, With the 21433 clean-up, you forgot saving the host-msrs for APs, causing the restore (at domain switch) to corrupt. I didn''t know how would you want to move around functions for a proper fix, but attached is a reference fix. thanks dulloor On Wed, May 26, 2010 at 6:48 AM, Xu, Jiajun <jiajun.xu@intel.com> wrote:>> On Tue, May 25, 2010 at 4:17 AM, Xu, Jiajun <jiajun.xu@intel.com> wrote: >>>> On 24/05/2010 16:51, "Xu, Jiajun" <jiajun.xu@intel.com> wrote: >>>> >>>>> 1. xen hypervisor hang when create guest on 32e platform >>>>> http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1617 >>> >>> The bug occurs each time when I created the guest.

Thanks for tracking this down, Dulloor. I will probably fold the call into vmx_cpu_up(), but anyhow I will apply a variant on your fix this morning.
