Upgrade kernel failed on Debian Squeeze vps

I’ve got some problems when upgrading the kernel on my VPS:

warning: grub-probe can't find drive for /dev/xvda. grub-probe: error: cannot stat `/dev/xvda'. run-parts: /etc/kernel/postinst.d/zz-update-grub exited with return code 1

So I have resolved this problem like this:

1. First let’s create /dev/xvda block device:

   $ sudo mknod /dev/xvda b 202 0

2. Edit /boot/grub/device.map file:

   Change

   (hd0) /dev/sda

   To

   (hd0) /dev/xvda

3. Edit /usr/sbin/update-grub file:

   Change

   find_device ()
   {
       if ! test -e ${device_map} ; then
           echo quit | grub --batch --no-floppy --device-map=${device_map} > /dev/null
       fi
       grub-probe --device-map=${device_map} -t device $1 2> /dev/null
   }

   to

   find_device ()
   {
           if ! test -e ${device_map} ; then
                   echo quit | grub --batch --no-floppy --device-map=${device_map} > /dev/null
           fi
           #grub-probe --device-map=${device_map} -t device $1 2> /dev/null
   
           echo /dev/xvda
   }

4. Run update-grub 0

5. Assuming your root disk is /dev/xvda1, run:

   sed -i "s/xvda/xvda1/g" /boot/grub/menu.lst

   The run ”apt-get upgrade” now.
