You *do* realize that in the DomU, as soon as you do "yum update",
you're effectively switched from CentOS 4.0 to CentOs 4.5, right?

What I did was to copy entire / from an installed CentOS 4.0 system to a partition.
Then I installed 2.6.9-42.0.3.EL.xs0.4.0.263xenU.rpm

If you have to use your own, install it first as CentOS 4.t and then
install the RHEL 4.5 kernel, version 3.1 RPM bundled kernel from
xensource.com, or build and install your own manually inside the
existing DomU.

I did'nt quiet get what you are trying to convey.What happens if I build another kernel in the domU environment.

Thanks for your valuable replies:)
