Hi there,

I have got fedora Core 7 installed as a host OS.
My requirement is to run CentOS 4.0 as a guest OS.
I have got the kernel source(2.6.9-5EL) , but I am unable to figure out how
compile the kernel for domU.
I apologize if this had been answered earlier.This is my first post.

I would be very grateful if someone can point me in right direction.
I read the whole user document that comes with xen 3.1 , but it does not
contain info  specific to
xen enabling a custom kernel for para-virtualization.
Can someone can point me to a good :).

Enabling an arbitrary custom kernel for paravirtualization can be tricky.

Is there any reason you can't use CentOS 4.5, which comes with Xen-enabled kernel for running in a domU? That would be my recommendation.
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?

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.
