[Xen-users] 2.6.20-1-amd64 Xen with RHEL5 guest

Hi

I am having some problems installing a paravirt RHEL guest on a deb amd64 xen

I have downloaded the RHEL 5 x86_64 cds, loop mounted disk 1, I have taken off 
the /isolinux/{initrd.img,vmlinux} and /images/xen/{initrd.img,vmlinux} files

When I boot from the /isolinux files, seems like the kernel is not
xen''ed so
will not boot. When I try and boot from the /images/xen, it boots, but it
can''t
find any block devices.  



Any idea''s hints ? is this the wrong list to be posting to ?

This is redundant (&wrong) when booting off the vmlinux & initrd.img
for purposes of installation. The initrd contains sets up the root
filesystem in a ramdisk for the install.

Better off using xvda & xvdb there

The ones in isolinux/ are for bare metal, so you always ned the /images/xen 
files for doing paravirt installs.

I am presuming you mean change sda & sdb with xvda xvdb

tried that 

i captured this of the console during the rhel boot up

okay made the changes to xvba & xvbb, went forward with the rhel5 install,
it
wants to partition up the drives. which I let it do in its default way - which 
means I have a /boot, pv1, pv2.
From the host machine how can I get to /boot for the vmlinux and the initrd?
I am presuming I need these to insert into my xen config file !

No need. Just use pygrub bootloader. eg instead of kernel + initrd config
options, use

  bootloader=''/usr/bin/pygrub''

It will automatically look in /boot for the guest disk & extract the default
kernel & initrd. If you use ''xm create -c'' it''ll
present you the usual grub
style menu for choosing a non-default kernel.

This is a debian host, what package is this part of and will it look in the 
guest disks for this information ?

pygrub is a standard part of Xen 3.0.3 releases or later, so I''d hope
its in
one of the Debian xen packages. As I mentioned below, it looks into the guest
disk to extract the default & initrd.
