Thanks for the reply.

I knew I'd miss some info. They are both the same virtual machine, identical 
create file (bar slight change in LV path), identical LV ( dd'd with the other 
machine) and using pygrub.

The only kernel I built myself was the SL Dom0 (as it was SL 6.2). Kernel in VM 
is  2.6.18-308.4.1.el5xen

Here is my config file....

name = "mail"
memory = "1524"
disk = [ 'phy:/dev/xen4/mail-root,xvda,w','phy:/dev/xen4/mail-swap,xvdb,w']
vif = [ 'mac=00:16:31:50:01:02, bridge=eth0' ]
bootloader="/usr/bin/pygrub"
vcpus=2
cpus='1-3'
on_reboot = 'restart'
on_crash = 'restart'


Nothing too startling there.


Thanks again,


Ian.
