Xen users - Dec 2006 - howto create a domU 2.4.18 kernel for xen 3.0.3

Hi,

Does anyone know of a howto or documentation for creating a xen 3.0.3
domU for the linux 2.4 kernel (specifically 2.4.18)?  My processor
doesn''t support full virtualization .... I am a developer and have a
legacy app. designed for 2.4.18 that I need to continue supporting for
bug fixes etc, but want to transition future development to the 2.6
kernel.

I would also appreciate a good description/documentation of how to go
about patching my 2.4.18 kernel for xen domU (or where I can find a
pre-made patch) or how to recompile my 2.4.18 kernel with xen domU
support.

Many thanks in advance,
-Jeremy

Are you shure you need that kernel?

I''m  new to xen but for a test loaded everything from server running 
redhat 6.2.
Was running 2.2.22. Xen is running 2.6.18.
It''s an old accounting system and want to reuse the hardware.

As I recall I copied everything into a lvm partition.
Fixed  up the fstab.
Changed ip as old server is still up.
Copied in the modules for the xen kernel.
A few error message but do not  think they matter.
Like it complains that /proc is already mounted.
Seems to work fine although my tests were not extensive.

John

Short answer: you don''t.  Use 2.6 or do full virtualization.

Old OS images arfe sometimes an adventure. Can you simply remount /proc to
clear the complaint?

Have you considered using linux-vserver?  We used to use it for our VDS 
accounts and it works great on older hardware.

http://linux-vserver.org

There''s some templates you can use for different distros at
