Xen users - Dec 2005 - Install and execute from CD of installation

I have Xen runnig fine under Fedora Core 4.
But I need execute under Xen a virtual machine with Red Hat 5.2 (an older
version).
Because the old version of Informix need the old kernel 2.0.36 and glibc
2.0.7.
This version of informix fails in the last versions of Linux.
My question is:
¿How can i install RedHat 5.2 on DomU from a iso image (or CD)?

Luis,

That''s a tough one. I think your best bet may be to install on another
machine, tar up the installation, then put it in Xen. Don''t forget, of
course, to copy over your DomU kernel modules. There are probably other
issues you''ll run into as well, 2.6 kernel will probably be too much
for
it, I''ve never installed a newer kernel on a distro that old. If I
recall correctly that was Kernel 2.0? or did they have a 2.2 kernel for
it?

It''s been a while since I was on 5.2 but I don''t think they
had any
concept of LVM, ext3 so I don''t think you would be successful in
installing it on the Xen machine outside of Xen on a LVM LV or anything.

Let me see if I can dig up a copy and look at the installer, it wasn''t
that sophisticated back then, it may be a matter of just installing some
packages with RPM and copying over the DomU kernel modules.

**after much searching**

Okay, can''t find 5.2 anywhere in my CD collection ( I did have it ), It
doesn''t look like it''s on the net anywhere either. If someone
can find
it, I''m sure I can script an install from Dom0 into an LVM LV or
something, shouldn''t be too tough. I won''t need the CD, just
an FTP site
somewhere. I''m sure someone is still mirroring that?

RH 5.2 runs on kernel 2.0.x. I had two legacy servers running this
distro. You can run older distros with a newer kernel, if you are lucky
and you don''t have any software that relies on older features (i.e.
bugs
;). I''d try to make a backup of the server with tar and copy it to your
Xen system. The DomU kernels don''t need that much modules or features.
You can even build a monolithic kernel without modules since the Dom0 is
dealing with the drivers. This saves you from upgrading the mod-utils
package.

You can always run the DomU without ext3 or LVM if you use the partition
or file backend.

Best,
