Xen users - Aug 2010 - suggest improvements in my doc to compile Xen from sources

Hi,
I am writing a small doc for people new to Xen.
to be able to compile Xen from sources on Ubuntu.

Please  suggest some improvements for this how to or mistakes that you
can point out.

There is a technique of virtualization known as Xen and a hypervisor
known as Xen.
Like you have Firefox,Open Office,VLC and other softwares on your
computer similary
there is a software known as Xen.

Technically it is  a hypervisor.Which runs in your computer
and this is what will be able to help you to install Guest Operating
Systems on your computer.

The term Xen is often confusing to newbies since the
technique of virtualization is also known as Xen and the
hypervisor is also known as Xen.

To be able to use Xen you need to have a system which has Linux installed.
Install Xen on it.

1) Understand what is the difference between PVM and HVM.
2) Understand how to create guest operating system on Xen (hypervisor)

This doc is for those people who want to compile the hypervisor Xen
for example you might have ever used vlc media player on your Linux box.

There you install it as

	yum install vlc or
	aptitude install vlc

If you download vlc from videolan website and do some steps as

	./configure
	make
	make install
	then this is what is known as compiling from sources.

	This doc will describe this procedure.


So to begin with get a Linux computer.

When I began I used a P4 with 256 MB RAM.
Technicall Xen can run in this low configuration but you will
 save a  lot of troubles
if you use a machine with higher RAM.



======================================================================================
sudo apt-get install iproute bridge-utils gcc make gettext
sudo apt-get install libcurl4-openssl-dev è openssl
sudo apt-get install python-dev zlib1g-dev bcc libsdl-dev pciutils-dev
è zlib

First we will compile latest XEN Hypervisor from source.

Go to http://www.xen.org/products/xen_source.html and download the
latest XEN hypervisor from here.

My hardware specifications uname -a

Linux tapas-laptop 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17
01:57:59 UTC 2009 i686 GNU/Linux


1. mkdir /home/tapas/xen
2. cd /home/tapas/xen
3. tar -xzf xen-4.0.0
4. cd xen-4.0.0
5. make xen
6. make install-xen
7. make tools
8. make install-tools

Build Vanilla kernel
Now we will build th PV_Ops Kernel. The Vanilla kernel source will be
downloaded from Jeremy''s tree. Jeremy''s git tree on kernel.org
contains the pv_ops dom0 patches. If we use Jeremy''s tree then we do
not any extra patches to bind XEN with kernel source.

1. mkdir /home/tapas/linux
2. cd /home/tapas/linux
3. git clone git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git
4. linux-2.6-xen
5. cd linux-2.6-xen
6. git checkout origin/xen/master -b xen/master
7. make menuconfig [see Note below]
8. make-kpkg clean
9. CONCURRENCY_LEVEL=N fakeroot make-kpkg --initrd
--append-to-version=-custom kernel_image kernel_headers
10. This will make the Ubuntu packages in the parent directory which
you can install

Note: Please choose the following xen specific optiions in kernel configuration.

Processor type and features ---> Subarchitecture Type (PC-compatible)

Hi Tapas, all
your idea is fine,I, for one, still use karmic koala + xen 3 from the
repository + 2.6.26-2 amd64/xen kernel from debian.
My configuration on my laptop is still fine though had some problems
that i''m tired of
(one for all, with this kernel and 3 giga of ram xorg work on the
dom0, with 4 giga fails!)

Best attempts i tried so far are the one at

http://virtualusr.wordpress.com/

even if i''m still unsuccessful.
I would suggest you to add to your document more and more details to
the interactions with grub/grub2
I''ll try your howto in september, right after a fresh installation of
lucid on a secondary usb hd.

BR
Luca

PV_ops right now suck due memory hotplug problems. xen-linux is much
better choice.
