I'm pretty sure that udev is a requirement for running Xen .. so
you should have it installed. Check if it is running by executing
this command:
ps -ef | grep udev
If it is you'll see something like:
skx@lappy:~$ ps -ef | grep udev
root 1063 1 0 13:13 ? 00:00:00 udevd --daemon
skx 5145 5120 0 17:24 pts/1 00:00:00 grep udev
(The first line "udevd --daemon" shows it is there.)
You can see if the package is installed by running "dpkg --list udev".
(The first column should show "ii" if it is installed.)
If it is running, and installed, then look at the file
/etc/udev/permissions.rules for me this contains the following:
KERNEL=="null", MODE="0666"
Here 666 is the permission for the /dev/null device, rather than
the 660 you appear to have. Change it to match and restart it with
"/etc/init.d/udev restart"
