 Ok, so you have to make sure those functionalities are either
compiled in the kernel or available as modules. Xen should put a
"config-<version>" file in the /boot directory with the compile time
kernel config used.

 You can reproduce any install using anaconda. Here's what I do:

 - produce kickstat files for the different profiles I need (you can
use a graphical tool to produce a kickstart file, start from scratch
or get one from /root just after an install)
 - setup a web server with the RPMs from the CDs
 - in the dom0 server, mount the partition that the domU will use
 - in the dom0, run:
 anaconda --text --headless \
   --rootpath="${installdir}" \
   --method="${baseurl}/${distribution}/i386/install" \
   --kickstart="${ksfile}"
 where "installdir" is the domU's partition mount point.

 I don't think that's possible with Xen 3.

 I don't think that the Xeon CPUs in the 1850 are VT enabled (the
1950 are). Just to make sure, please to a:

 cat /proc/cpuinfo | grep flags

 and look for "vmx". If it's there, you have VT.
