What is your problem exactly? Sorry...

2010/3/26 Outback Dingo <outbackdingo@xxxxxxxxx>

so any thoughts on getting around this issue guys?

2010/3/26 Martinx - ジェームズ <thiagocmartinsc@xxxxxxxxx>

Sure! My /boot partition is at the beginning of the disc and it is ext2.

2010/3/26 Outback Dingo <outbackdingo@xxxxxxxxx>

more information is its running ext4 from lvm on sda5

/dev/sda5 on / type ext4 (rw,errors=remount-ro)

proc on /proc type proc (rw)

so in the grub config i have

cat /etc/grub.d/40_custom
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change

# the 'exec tail' line above.
menuentry "Xen 4.0.0-rc8 / Ubuntu 10.4 kernel 2.6.32.10 pvops" {

this is running on the kernel from jeremys tee

Mmm... Your system is 64 bits?!
You try the Linux 2.6.32.10 from Jeremy's tree without Xen?!

2010/3/26 Outback Dingo <outbackdingo@xxxxxxxxx>

hrmm ok, well Ive gotten all the way to the end and tried to reboot into XEN

during the boot process i see

elf_xen_note_check

will only load images built for generic load or linux images

Panic on CPU0

could not setup DomU Guest OS

reboot in 15 seonds

any thoughts???

Hi!

This is a quick guide to help us to try the new Xen.
Also I have the composite window manager on top of the Xen! With full 3D support!

To achieve this I do:

1- Install your Ubuntu Desktop 10.4 beta1 and upgrade your system;

1.1 - Install some packages:

aptitude install build-essential libncurses5-dev dpkg-dev debhelper fakeroot

2- Download and install a new kernel with dom0 pv_ops enabled:

sudo -s
cd /usr/src
git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git linux-2.6-xen
cd linux-2.6-xen
git pull
git reset --hard
git checkout -b xen/stable origin/xen/stable
git pull

2.1 - Download the kernel config file attached to this mail (config-for-xen-2.6.32.10-pvops):

Copy the config file to the kernel source dir:

cp ~Downloads/config-for-xen-2.6.32.10-pvops /usr/src/linux-2.6-xen/.config

You can see the differences of my config file against the Lucid one:

diff /boot/config-2.6.32-17-generic ~Downloads/config-for-xen-2.6.32.10-pvops | vim -

...both are close to each other.

2.2 Configure, compile and install:

make menuconfig # Enable the dom0 support and the Xen backend/frontend/xenfs stuffs...
make
chmod g-s /usr/src -R    # To avoid the error: "dpkg-deb: control directory has bad permissions 2755 (must be >=0755 and <=0775)"
make dep-pkg
dpkg -i ../linux-image*2.6.32.10*.deb
depmod 2.6.32.10
update-initramfs -c -k 2.6.32.10
update-grub
echo "xen-evtchn" >> /etc/modules

Now you can try your new kernel without Xen, if you want, it should work smootly.

3- Download and install the latest Xen:

Preparing your environment:

apt-get build-dep xen-3.3
aptitude install uuid-dev iasl texinfo

Download and compile:

cd /usr/src
hg clone -r 4.0.0-rc8 http://xenbits.xensource.com/xen-unstable.hg
cd xen-unstable.hg
make xen
make tools
make stubdom
make install-xen
make install-tools PYTHON_PREFIX_ARG=
make install-stubdom

update-rc.d xend defaults 20 21
update-rc.d xendomains defaults 21 20

4- Configuring your Grub2 through the file /etc/grub.d/40_custom:

---- cut here ----
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.
menuentry "Xen 4.0.0-rc8 / Ubuntu 10.4 kernel 2.6.32.10 pvops" {
insmod ext2
set root=(hd0,1)
multiboot (hd0,1)/xen-4.0.0-rc8.gz dummy=dummy
module (hd0,1)/vmlinuz-2.6.32.10 dummy=dummy root=/dev/mapper/HyperDeskVG01-tcmc--dell--lucid ro
module (hd0,1)/initrd.img-2.6.32.10
}
---- cut here ----

Don't forget to change your "root=" option of your Linux!

Run update-grub again:

update-grub

5- Reboot into your new dom0!

reboot

6- Look if your Xen is up and running

xm list
xm info

.. if not:

/etc/init.d/xendomains stop
/etc/init.d/xend stop
/etc/init.d/xend start
/etc/init.d/xendomains start

xm list
xm info

-
Cheers!
Thiago
