1. I would suggest you to obtain a serial log and escalate the problem to
xen-devel.
2. Could you post yours /usr/src/linux-2.6-xen/.config ( gzipped)
,/boot/grub/grub.cfg,
"df -h" output.

bit version using the tutorial
at http://bderzhavets.wordpress.com/2010/04/24/set-up-ubuntu-10-04-server-pv-domu-at-xen-4-0-dom0-pvops-2-6-32-10-kernel-dom0-on-top-of-ubuntu-10-04-server/
on a Lenovo thinkcentre workstation.
When I boot I get a kernel panic. If I boot the Linux kernel that I compiled
using the tutorial on it''s own it boots fine.
Is the likely cause hardware? is there a common error made in this tutorial that
would
cause a panic on boot.

+CONFIG_XEN_BLKDEV_TAP=y
+CONFIG_XEN_BLKBACK_PAGEMAP=y
I attached mine config and config.patch.
Make diff one more time on your box and watch errors for yourself
The best option - just use config attached after git pull ( 2.6.32.16 )
2. Second.
Please submit your working grub entry for Xen (just one) and "df -h"
for corresponding vanilla entry. /dev/sdb5 and (hd0,1) seem strange to me.

I have tried 4 time unsuccessfully to install Xen 4 on Ubuntu Lucid (10.4) 64
bit version using the
tutorial
at http://bderzhavets.wordpress.com/2010/04/24/set-up-ubuntu-10-04-server-pv-domu-at-xen-4-0-dom0-pvops-2-6-32-10-kernel-dom0-on-top-of-ubuntu-10-04-server/
on a Lenovo thinkcentre workstation.
When I boot I get a kernel panic. If I boot the Linux kernel that I compiled
using the tutorial on it''s own it boots fine.
Is the likely cause hardware? is there a common error made in this tutorial that
would
cause a panic on boot.

I would also disable UUID via /etc/default/grub
# Uncomment if you don''t want GRUB to pass "root=UUID=xxx"
parameter to Linux
GRUB_DISABLE_LINUX_UUID=true
and
# update-grub
Not sure it''s required , but cannot make things worse.
Just always disabled UUID for Xen Instances on Lucid,Karmic (Grub2)

1. I would suggest you to obtain a serial log and escalate the problem to
xen-devel.
2. Could you post yours /usr/src/linux-2.6-xen/.config ( gzipped)
,/boot/grub/grub.cfg,
"df -h" output.

I have tried 4 time unsuccessfully to install Xen 4 on Ubuntu Lucid (10.4) 64
bit version using the
tutorial
at http://bderzhavets.wordpress.com/2010/04/24/set-up-ubuntu-10-04-server-pv-domu-at-xen-4-0-dom0-pvops-2-6-32-10-kernel-dom0-on-top-of-ubuntu-10-04-server/
on a Lenovo thinkcentre workstation.
When I boot I get a kernel panic. If I boot the Linux kernel that I compiled
using the tutorial on it''s own it boots fine.
Is the likely cause hardware? is there a common error made in this tutorial that
would
cause a panic on boot.

I attached mine config and config.patch.
Make diff one more time on your box and watch errors for yourself
The best option - just use config attached after git pull ( 2.6.32.16 )
2. Second.
Please submit your working grub entry for Xen (just one) and "df -h"
for
corresponding vanilla entry. /dev/sdb5 and (hd0,1) seem strange to me.

Per "howto" create entry into /boot/grub/grub.cfg:-
menuentry "Xen 4 / Ubuntu 10.04 kernel
2.6.32.16-xen" {insmod ext2set root=''(hd0,1)''multiboot
(hd0,1)/boot/xen.gz dummy=dummymodule (hd0,1)/boot/vmlinuz-2.6.32.16-xen
dummy=dummy
root=/dev/sda1 ro nopat console=tty0
module (hd0,1)/boot/initrd.img-2.6.32.16-xen}
Entry dummy=dummy is important at kernel line. It was skipped.
It causes a crash. Build 2.6.32.16 kernel with submitted config (64 bit) :-
# cd /usr/src/linux-2.6-xen
# git pull
# cp ../config.071310 .config
# aptitude install kernel-package fakeroot
# export CONCURRENCY_LEVEL=(number_of_cores) +1
# make-kpkg clean
# fakeroot make-kpkg --initrd --append-to-version=-xen kernel-image
kernel-headers
# update-initramfs -c -k 2.6.32.16-xen
and see what happens
Boris.

I attached mine config and config.patch.
Make diff one more time on your box and watch errors for yourself
The
best option - just use config attached after git pull ( 2.6.32.16 )
2. Second.
Please submit your working grub entry for Xen (just one) and "df -h"
for corresponding vanilla entry. /dev/sdb5 and (hd0,1) seem strange to me.

I have tried 4 time unsuccessfully to install Xen 4 on Ubuntu Lucid (10.4) 64
bit version using the
tutorial
at http://bderzhavets.wordpress.com/2010/04/24/set-up-ubuntu-10-04-server-pv-domu-at-xen-4-0-dom0-pvops-2-6-32-10-kernel-dom0-on-top-of-ubuntu-10-04-server/
on a Lenovo thinkcentre workstation.
When I boot I get a kernel panic. If I boot the Linux kernel that I compiled
using the tutorial on it''s own it boots fine.
Is the likely cause hardware? is there a common error made in this tutorial that
would
cause a panic on boot.
Murray

Re: [Xen-users] Xen 4 Ubuntu Lucid panics (HTML typos fixed)
Tried to fix "CR" coming from HTML cat and paste
Create entry like this :-
menuentry "Xen 4 / Ubuntu 10.04 kernel 2.6.32.16-xen" {
insmod ext2
set root=''(hd0,1)''
multiboot (hd0,1)/boot/xen.gz dummy=dummy
module (hd0,1)/boot/vmlinuz-2.6.32.16-xen dummy=dummy root=/dev/sda1 ro nopat
console=tty0
module (hd0,1)/boot/initrd.img-2.6.32.16-xen
}
Entry dummy=dummy is important at kernel line. It was skipped.
It causes a crash. Build 2.6.32.16 kernel with submitted config (64 bit) :-
# cd /usr/src/linux-2.6-xen
# git pull
# cp ../config.071310 .config
# aptitude install kernel-package fakeroot
# export CONCURRENCY_LEVEL=(number_of_cores) +1
# make-kpkg clean
# fakeroot make-kpkg --initrd --append-to-version=-xen kernel-image
kernel-headers
# update-initramfs -c -k 2.6.32.16-xen
and see what happens
Boris.

Re: [Xen-users] Xen 4 Ubuntu Lucid panics ( Xen >=4.0.1-rc2)
I forgot kernel >=2.6.32.15 requires Xen 4.0.1-rc2 at least
So build Xen as follows :-
# cd /usr/src
# hg clone http://xenbits.xensource.com/xen-4.0-testing.hg
# cd xen-4.0-testing.hg
# make xen
# make tools
# make install-xen
# make install-tools PYTHON_PREFIX_ARG
Boris.

Per tutorial :-

Now
# diff -auN config.received config.071310 > conf.patch
# cat conf.patch
. . . . . .
-# CONFIG_XEN_NETDEV_BACKEND is not set

+CONFIG_XEN_NETDEV_BACKEND=y
+CONFIG_XEN_BLKDEV_BACKEND=y
+CONFIG_XEN_BLKDEV_TAP=y
+CONFIG_XEN_BLKBACK_PAGEMAP=y
I attached mine config and config.patch.
Make diff one more time on your box and watch errors for yourself
The
best option - just use config attached after git pull ( 2.6.32.16 )
2. Second.
Please submit your working grub entry for Xen (just one) and "df -h"
for corresponding vanilla entry. /dev/sdb5 and (hd0,1) seem strange to me.
Boris.

1. I would suggest you to obtain a serial log and escalate the problem to
xen-devel.
2. Could you post yours /usr/src/linux-2.6-xen/.config ( gzipped)
,/boot/grub/grub.cfg,
"df -h" output.
Boris.

I have tried 4 time unsuccessfully to install Xen 4 on Ubuntu Lucid (10.4) 64
bit version using the
tutorial
at http://bderzhavets.wordpress.com/2010/04/24/set-up-ubuntu-10-04-server-pv-domu-at-xen-4-0-dom0-pvops-2-6-32-10-kernel-dom0-on-top-of-ubuntu-10-04-server/
on a Lenovo thinkcentre workstation.
When I boot I get a kernel panic. If I boot the Linux kernel that I compiled
using the tutorial on it''s own it boots fine.
Is the likely cause hardware? is there a common error made in this tutorial that
would
cause a panic on boot.
