Hello,
I have installed xen3.1 from the tarball on a centos5 OS
I have followed up these instructions :
"$ cd dist
$ su -
# sh ./install.sh
After installation, you will still need to modify your grub.conf to
enable booting xen. Typically this means adding an entry like
title My Distro with Xen (2.6.18-xen-3.1)
root (hd0,0)
kernel /xen-3.1.0.gz
module /vmlinuz-2.6.18-xen ro root=/dev/<foo>
module /initrd-2.6.18-xen
... obviously replacing <foo> with the name of your root device. "
So I have added this in my grub.conf file
title Centos5 with Xen (2.6.18-xen-3.1)
root (hd0,0)
kernel /xen-3.1.0.gz
module /vmlinuz-2.6.18-xen ro root=/dev/sda2
I didn''t find any initrd-2.6.18-xen file in the /boot partition !
Also when I reboot on the new kernel I have a kernel panic telling me
that it doesn''t find my root partition !
My disk are under raid1 with a 9550sx 3ware card (driver is included
from 2.6.14)
Also my root partition is /dev/sda2
Sys. de fich. Tail. Occ. Disp. %Occ. Monté sur
/dev/sda2 19G 1,4G 17G 8% /
/dev/sda1 244M 24M 207M 11% /boot
tmpfs 2,0G 0 2,0G 0% /dev/shm
So do I have to create the initrd-2.6.18-xen
Any idea why it doesn''t find my root partition ?
Thanks
Pascal

Re: [Xen-users] Xen 3.1 initrd (from tarball) and kernel panic
Thanks Dylan, But it is on my dom0 not when I try to create a domU I''ve done a fresh minimal install of centos5 and wanted xen3.1 rather than the 3.0.3 centos5 xen package So I''ve downloaded the last xen tarball and did an install (cd dist/ then ./install.sh) The kernel panic I have telling me it doesn''t find my root partittion is when I reboot my box and so when it tries to start with the new xen kernel Pascal Dylan Martin a écrit :> You''ll have to create the initrd.

Re: [Xen-users] Xen 3.1 initrd (from tarball) and kernel panic
I have done a mkinitrd /boot/initrd-2.6.18-xen.img 2.6.18-xen and added in the grub.conf module /initrd-2.6.18-xen But I still have a panic kernel. The box reboot so I don''t see all the messages. it talks about /dev/root which doesn''t exist and tell that it doesn''t find the root partition Any idea why ? Do you think it is because I have a raid1 with a 3ware card (9560). Normaly the driver for this card has been added in kernel2.6.14 so it should be in the xen kernel 2.6.18 ?
