Different from how to install xen on Ubuntu 9.10, Ubuntu 10.04 does not officially maintain the xen software package and does not have the corresponding xen-tools,

That is, the third-party Dom0 kernel is not ready-made. Therefore, it can only be installed by source code.

All of the following operations are performed under the Super User.

# Installation steps:

1. Install the required package

Apt-get install libcurl4-openssl-dev \

Xserver-xorg-dev \

Mercurial gitk \

Build-essential \

Libncurses5-dev \

Uuid-dev gawk \

Gettext texinfo bcc \

Libncurses5-dev dpkg-dev debhelper \

Iasl texinfo bridge-utils bison flex python-dev

Other security kits required for Debian/Ubuntu 64bit

Apt-get install gcc-multilib

2. source code of the Dom0 kernel (about 350 MB)

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 checkout-B xen/stable-2.6.32.x origin/xen/stable-2.6.32.x

3. Compile the Dom0 Kernel

Change 'extraversion' in Makefile to what you want.

Make menuconfig # Enabled the dom0 support and the Xen backend as usual on Ubuntu 9.10

Make-j (x) number_of_kernels

Make modules_install install

Chmod g-s/usr/src-R

Make deb-pkg

Dpkg-I ../linux-image * 2.6.32.27 *. deb

Depmod 2.6.32.27

Update-initramfs-c-k 2.6.32.27

4. Download the source code xen4.0.1 and compile and install it.

Cd/usr/src

Hg clone http://xenbits.xensource.com/xen-4.0-testing.hg

Cd xen-4.0-testing.hg

Make xen tools stubdom

Make install-xen

Make install-tools PYTHON_PREFIX_ARG =

5. Add it to the automatic start script.

Update-rc.d xend defaults 20 21

Update-rc.d xendomains defaults 21 20

6. Modify grub2 entry, reboot

Menuentry "Xen 4.0.1/Ubuntu 10.04 kernel 2.6.32.27 "{

Insmod ext2

Set root = '(hd0, 7 )'

Multiboot (hd0, 7)/boot/xen-4.0.1.gz dummy = dummy dom0_mem = 1024 M

Module/boot/vmlinuz-2.6.32.27 dummy = dummy nopat root = UUID = 013228f1-cae3-4f2f-aa52-b025785d3aa6 ro console = tty0

Module (hd0, 7)/boot/initrd. img-2.6.32.27

}

Note:

-The dummy = dummy parameter must be added to grub2 to enable normal startup.

-Dom0_mem must be large enough to enable Dom0 to start properly. Otherwise, Dom0 will be restarted automatically.
