Bcc: Roland Lammel <lammelr at pc09.NeoTel.local>

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)

IMO, this is a typical miss-configuration of the guest. What did you
configure in /etc/inittab as console? What is your domU kernel command
line options (especially those regarding the console)? What kernel do
you run for this CentOS guest? Are you using pygrub, and the kernel
inside the domU, or the 3.2 Linux kernel from dom0?

Well, since the console device has been renamed in newer Linux kernels,
you do have some manual work to do, and I don't think you should write
that this is a Xen bug.

Please include your domU startup file in this bug report.
