lastest xen unstable crash
Hi everyone,
I was trying to build a new machine but the system keeps rebooting.

I have tried with Fedora 16 (kernel 3.3.0-8) and Xubuntu 11.10 (3.0.0.17-generic).
The output to my serial console is attached.
Cheers,

[PATCH v3 0/4] nested vmx: enable VMCS shadowing feature

[PATCH RFC v13 00/20] Introduce PVH domU support
This patch series is a reworking of a series developed by Mukesh
Rathor at Oracle. The entirety of the design and development was done
by him; I have only reworked, reorganized, and simplified things in a

for this effort therefore goes to him. This version is labelled v13
because it is based on his most recent series, v11.
