Hi Xen list,

I had Xen 3.0.2 (from the xensource.com binary packages) running on an Ubuntu 6.06 (with a 2.6 kernel).
I made an image of a Redhat Advanced Server 3 that I boot fine; my problem is that the RHAS DomU is booting on the Dom0 2.6 kernel where I would like it to boot on the 2.4 kernel shipped with RHAS3.

I understand I need to build a custom 2.4 kernel patched with Xen, but how do I do that? Do I build this from Dom0? Or DomU?
I guess that's a common operation, as a lot of people are running different kernels on their DomUs, but would anyone have pointers or advices on how to proceed?

The only way to (without a lot of hard work) get a 2.4 kernel onto a Xen system is to use the HVM feature - but that means that you need a processor with hardware virtualization to do that...

Any help greatly appreciated.

Cheers,

Quentin.

Hi,

Thanks for the quick reply - what would a lot of hard work imply? Having this configuration and the RHAS image running was quite a lot of hard work as well, so I'm not scared :)

Cheers,
Quentin
