OS: Ubuntu 9.04 server (64-bit)

Installing Xen on Ubuntu 9.04

># apt-get install ubuntu-xen-server

1. Get the xen binary packages from the following web sites:

* It seems that the package is no longer exists in the ftp server (2011/02/23)

># wget http://ftp.debian.org/debian/pool/main/l/linux-2.6/linux-modules-2.6.26-2-xen-amd64_2.6.26-21_amd64.deb

># wget http://ftp.debian.org/debian/pool/main/l/linux-2.6/linux-image-2.6.26-2-xen-amd64_2.6.26-21_amd64.deb

># sudo dpkg -i linux-modules-2.6.26-2-xen-amd64_2.6.26-21_amd64.deb 

># sudo dpkg -i linux-image-2.6.26-2-xen-amd64_2.6.26-21_amd64.deb

After the xen kernel package installation, it should update the grub boot loader automatically, but

just in case, here is an example. 

># vi /boot/grub/menu.lst

title   Xen 3.3 / Ubuntu 9.04, kernel 2.6.26-2-xen-amd64

module    /boot/initrd.img-2.6.26-2-xen-amd64

quiet

># reboot

Installing a virtual machine (domU)

* using xen-create-image to create a VM, 

># vim /etc/xen-tools/xen-tools.conf

memory = 512Mb    # Memory size

swap   = 512Mb      # Swap size

fs     = ext3            # use the EXT3 filesystem for the disk image.

dist   = jaunty         # Default distribution to install.
