Installing Xen on Ubuntu 10.04

I used to be able to install Xen on 9.04 with binary format seamlessly somewhat. But after upgrading to 10.04, I am not sure whether the installation would work seamless as it was on 9.04. 

There are many tutorials on installing Xen 4.0 on 10.04 by compiling source codes, but I just want to install xen with the binary to make it simpler. 

Let me try with installing older version on 10.04. Here we go....

Install Xen 3.0.3(?) from binary (tried - no luck)

># sudo apt-get install ubuntu-xen-server

Add jaunty distribution to sources.list

># vim /etc/apt/sources.list

deb http://kr.archive.ubuntu.com/ubuntu/ jaunty main restricted universe multiverse

deb-src http://kr.archive.ubuntu.com/ubuntu/ jaunty main restricted universe multiverse

># apt-get update

># apt-get install ubuntu-xen-server

It seems like there is a bug. 

I can't find solutions for this so I guess I just have to install xen from source. From here on, I am following #2 guideline. 

Installing Xen 4.0 from source

># mkdir xen4x; cd xen4x

># wget -q -O - \

catdoc > .sh; sh .sh

1. To build xen-hypervisor 

># debian/bin/packageXen40x.sh

2. To install build binary files

For xen packages,

># sudo dpkg --purge --force-depends python-xml

># sudo dpkg -i /usr/src/build-lucid/python-xml/python-xml_0.8.4-10.1ubuntu2*.deb

># cd /usr/src/build-lucid

># sudo dpkg --purge --force-depends libxen4-dev libxen4 python-xen-4.0 xen-docs-4.0 xen-hypervisor-4.0 xen-utils-4.0

># sudo dpkg -i libxen4-dev_4.0.1-0ubuntu2_amd64.deb libxen4_4.0.1-0ubuntu2_amd64.deb python-xen-4.0_4.0.1-0ubuntu2_amd64.deb xen-docs-4.0_4.0.1-0ubuntu2_all.deb xen-hypervisor-4.0_4.0.1-0ubuntu2_amd64.deb xen-utils-4.0_4.0.1-0ubuntu2_amd64.deb

3. To build xen-kernel 

># head debian/bin/kpkgXenKernel.sh

#!/bin/bash -x

# ./kpkg2XenKernel.sh

# Use:

# ./kpkg2XenKernel.sh  stable-2.6.31.x 100402212843  #or# ./remakeXenKernel.sh stable-2.6.31.x f3d5fe8050

# ./kpkg2XenKernel.sh  stable-2.6.32.x 100430201127  #or# ./remakeXenKernel.sh stable-2.6.32.x 4dd582f35f

# ./kpkg2XenKernel.sh  stable-2.6.32.x 100517202304  #or# ./remakeXenKernel.sh stable-2.6.32.x ba739f9abd

# ./kpkg2XenKernel.sh  stable-2.6.33.x               # picks up the last commit

# TWEAKCONFIG=yes ./kpkg2XenKernel.sh  stable-2.6.32.x  # Configuration before the build of the last commit

Select the appropriate kernel

># debian/bin/kpkgXenKernel.sh stable-2.6.32.x

Install and config grub config. 

># dpkg -i linux-image-2.6.32.27-xen_101210011616_amd64.deb linux-headers-2.6.32.27-xen_101210011616_amd64.deb

># ls /lib/modules

># mkinitramfs -o /boot/initrd.img-2.6.32.27-xen 2.6.32.27-xen

Edit grub configuration 

* Make sure to add the following line.

># vim /boot/grub/menu.lst

...

module      /boot/initrd.img-2.6.32.27-xen

...

># reboot

 ** 2.6.32.27 DOES NOT WORK T.T **

Let me try with 2.6.31.x

># debian/bin/kpkgXenKernel.sh  stable-2.6.31.x 100402212843

Install and config grub config. 

># dpkg -i linux-headers-2.6.31.12-xen_100402212843_amd64.deb linux-image-2.6.31.12-xen_100402212843_amd64.deb

># ls /lib/modules

># mkinitramfs -o /boot/initrd.img-2.6.31.12-xen 2.6.31.12-xen

Edit grub configuration 

* Make sure that the following line is included. 

># vim /boot/grub/menu.lst

...

module      /boot/initrd.img-2.6.31.12-xen

...

># reboot

** 2.6.31.12 WORKS **

Let's try installing a VM, then...

># wget http://xen-tools.org/software/xen-tools/xen-tools_4.2-1_all.deb

># apt-get install xen-tools_4.2-1_all.deb

># vim /etc/xen-tools/partitions.d/green

[root]

size=2G

type=ext3

mountpoint=/

options=sync,errors=remount-ro

[swap]

size=512M

type=swap

># sudo xen-create-image --hostname=green1 --ip=192.168.1.164  --gateway=192.168.1.1 --netmask=255.255.255.0  --broadcast=192.168.1.255 --dist=lucid  --mirror=http://kr.archive.ubuntu.com/ubuntu --size=2Gb  --memory=512Mb  --arch=amd64 --partitions=green  --force --boot --passwd --role udev --dir /home/xen

Installing a VM with virt-manager

* At the moment, I am not sure how to fix this.
