Package: xen-utils-common
Version: 4.1.2-1
Severity: important

Dear Maintainer,

   * What led up to the situation?

   Upgrade of Linux kernel to 3.2 (testing) and Xen to 4.1 (testing)
   from Debian Stable (Squeeze) 

   * What exactly did you do (or not do) that was effective 
     (or ineffective)?

   Upgrading Xen to 4.1 (from 4.0.1) and Linux kernel to 3.2 (from 
   stable 2.6.32) by using apt-pinning to select the packages for 
   linux-image and xen.

   * What was the outcome of this action?

   Xen guests did not boot correctly (CentOS 4.9 hang on hardware
   initialization) and xm console is not working (hangs without any
   output)

   * What outcome did you expect instead?

   Xen guests boot and xm console works

It appears the cause of this issue is a missing loaded module named
xen-gntdev.

Patching /etc/init.d/xend to modprobe for xen-gntdev fixes this issue.
(Sorry, patch inline)
