How do you install the base system? Can you do this using anaconda? (I'm not a Redhat person, pity I have to run it ).
I was using debootstrap on Unbuntu, which worked like a charm.

That's what I understood from the previous thread I had on the list, if I can have multiple DomUs with 
2.4 kernel running Redhat AS3, even if it's not the standart Redhat kernel, I'll be very happy !!

I am using Dell Poweredge 1850 with Xeon processors - no idea whether this is VT compatible.

  Maybe it is compiled in the kernel and the error you get at boot
comes from another missing module ? When you boot the regular RHEL 3
kernel, what is the output of 'lsmod' ?

  There are lots of different ways to install a RHEL 3 domU, even dom0
is not running RHEL 3. I'm using anaconda for example so that I can
reuse our kickstart infrastructure.

  You cannot have a non-xen aware kernel as a domU when using non-VT hardware.

  Well, I guess the only way to make this work (i.e having a standard
RHEL 3 kernel) is to use a VT enabled server.
