1) You need to install ubuntu 12.04 (64 bit) on one machine. I am proceeding to next step assuming you have machine with ubuntu installed.
2) Install Xen:
I am going to download Xen source code and going to compile it, for this purpose I need some libraries installed on machine.

Prerequisites are-
* GCC v3.4 or later
* GNU Make
* GNU Binutils
* Development install of zlib (e.g., zlib-dev)
* Development install of Python v2.3 or later (e.g., python-dev)
* Development install of curses (e.g., libncurses-dev)
* Development install of openssl (e.g., openssl-dev)
* Development install of x11 (e.g. xorg-x11-dev)
* Development install of uuid (e.g. uuid-dev)
* bridge-utils package (/sbin/brctl)
* iproute package (/sbin/ip)
* hotplug or udev
* GNU bison and GNU flex
* GNU gettext
* 16-bit x86 assembler, loader and compiler (dev86 rpm or bin86 & bcc debs)
* ACPI ASL compiler (iasl)
root@dom0$ sudo su
root@dom0$ apt-get install bcc bin86 gawk bridge-utils iproute libcurl3 libcurl4-openssl-dev bzip2 module-init-tools transfig tgif texinfo texlive-latex-base texlive-latex-recommended texlive-fonts-extra texlive-fonts-recommended pciutils-dev mercurial build-essential make gcc libc6-dev zlib1g-dev python python-dev python-twisted libncurses5-dev patch libvncserver-dev
root@dom0$ apt-get install libsdl-dev libjpeg62-dev iasl libbz2-dev e2fslibs-dev git-core uuid-dev ocaml libx11-dev bison flex xz-utils ocaml-findlib gcc-multilib
Download Xen 4.3.0 source code:
root@dom0# wget http://bits.xensource.com/oss-xen/release/4.3.0/xen-4.3.0.tar.gz
Now we can extract, build and install it:
root@dom0# tar xvf xen-4.3.0.tar.gz root@dom0# cd xen-4.3.0 root@dom0# make xen root@dom0# make tools root@dom0# make stubdom root@dom0# make install-xen root@dom0# make install-tools PYTHON_PREFIX_ARG= root@dom0# make install-stubdom
We should have the following files in ‘/boot’ directory:
/boot/xen.gz /boot/xen-4.gz /boot/xen-4.3.gz /boot/xen-4.3.0.gz
Now, in the file ‘/etc/xen/xend-config.sxp’ we enable the following option:
#(xend-unix-server no) --> (xend-unix-server yes)
3) Compile kernel for Dom0 :
Download kernel from kernel org:
Download kernel from kernel org:
root@dom0# wget http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.8.1.tar.gz
Extract it
root@dom0# tar xvf linux-3.8.1.tar.gz
we can configure our new kernel by running:
We need to set some parameters-
We need to set some parameters-
root@dom0# cd linux-3.8.1
root@dom0# make menuconfig

Below, is a list of options needed to compile Linux kernel with dom0 support: (save to ".config")
Modify in config file: ".config"
CONFIG_ACPI_PROCFS=y CONFIG_XEN=y CONFIG_XEN_MAX_DOMAIN_MEMORY=32 CONFIG_XEN_SAVE_RESTORE=y CONFIG_XEN_DOM0=y CONFIG_XEN_PRIVILEGED_GUEST=y CONFIG_XEN_PCI=y CONFIG_PCI_XEN=y CONFIG_XEN_BLKDEV_FRONTEND=y CONFIG_XEN_NETDEV_FRONTEND=y CONFIG_XEN_KBDDEV_FRONTEND=y CONFIG_HVC_XEN=y CONFIG_XEN_FBDEV_FRONTEND=y CONFIG_XEN_BALLOON=y CONFIG_XEN_SCRUB_PAGES=y CONFIG_XEN_DEV_EVTCHN=y CONFIG_XEN_GNTDEV=y CONFIG_XEN_BACKEND=y CONFIG_XEN_BLKDEV_BACKEND=y CONFIG_XEN_NETDEV_BACKEND=y CONFIG_XENFS=y CONFIG_XEN_COMPAT_XENFS=y CONFIG_XEN_XENBUS_FRONTEND=y CONFIG_XEN_PCIDEV_FRONTEND=y
Now, we can build and install the kernel:
user@dom0$ sudo make root@dom0$ sudo make modules_install root@dom0$ sudo make install root@dom0$ cd /boot root@dom0$ sudo mkinitramfs -o initrd.img-3.7.1 3.7.1 root@dom0$ sudo update-grub
We can now reboot our system to the Xen enabled 3.8.1 Linux kernel. To verify that Xen is running we can do the following:
$ uname -a > Linux 3.8.1$ cd /lib/modules/3.8.0-29-generic/kernel/drivers/xen $ modprobe xen-evtchn $ mount -t xenfs none /proc/xen.
root@dom0$ cat /proc/xen/capabilities
The output must be same as the following line:
control_d
You can manually start xen daemons with-
$ /sbin/ldconfig
service xencommons start
