Default Error starting updated Ubuntu servers

Hi all,After applying some updates onto a Ubuntu web server, I rebooted it.
However it will no longer start, and generates this error in XenCenter:

22/12/2011*09:57:45 Error: Starting VM 'Web Server' - Using <class 'grub.GrubConf.Grub2ConfigFile'>; to parse /boot/grub/grub.cfg - WARNING:root:Unknown directive load_video*- WARNING:root:Unknown directive terminal_output - Traceback (most recent call last): - File "/usr/bin/pygrub&quot;, line 746, in ? - raise RuntimeError, "Unable to find partition containing*kernel"; - RuntimeError: Unable to find partition containingkernel

This server is mission-critical, so we need it back as soon as possible.
Any ideas guys?
thanks for the help,
--regards,

Can you confirm that the updates were completed successfully? The error here states that it is unable to find the the kernel (vmlinuz).

Is it possible to boot this VM using a previous snapshot?



Alternatively, you could try a few things from online articles:

1. http://eng.eelcowesemann.nl/linux-unix/xenserver/partition-containing-kernel-xenserver/



2. On this page
(http://blog.403labs.com/post/1546501840/paravirtulization-with-citrix-xenserver-5-5-and-ubuntu),
the solution outlined is the following -

xe vm-param-set uuid=<UUID> PV-bootloader-args="--kernel=/vmlinuz-2.6.32-21-server --ramdisk=/initrd.img-2.6.32-21-server"
Replace the parameters according to your settings.
