I assume you have something like this in your elilo.conf:

root=/dev/VolGroup00/LogVol00
append="com1=115200,8n1 -- xencons=ttyS0 console=ttyS0 ro"

Older versions of elilo stuff the root= option in on the wrong side of
the "--", passing the option to Xen instead of the Linux kernel.  The
simple fix is to either update elilo or change elilo.conf to:

append="com1=115200,8n1 -- root=/dev/VolGroup00/LogVol00 xencons=ttyS0 
console=ttyS0 ro"

(removing the separate root= line)

Thanks,
