[Xen-devel] x86/AMD: Nested hvm crashes in 4.3

[Suravee Suthikulanit <suravee.suthikulpanit@xxxxxxx>]

Hi Jan,

I have found an issue in where the system crash right when I start 
another HVM guest inside an HVM guest.  I have traced back to the patch 
which the issue started.

The issue doesn't reproduce when starting a PV (L2) guest inside an HVM 
(L1) guest.

PS: The L2 Xen is running Xen-4.3, but I think the issue is at the L1 
Xen since it crashes the system.
