Compiling Xen-4.4 From Source And Installing It On Ubuntu Server (Amd-64)

1 $ git clone git://xenbits.xen.org/xen.git

If you have not yet install "git", please run "sudo apt-get install git" on your terminal.

1 $ cd xen

Use "git branch" to show the versions of Xen: 

 1 $ git branch -av
 2   master                     3e2331d VT-d: suppress UR signaling for further desktop chipsets
 3   remotes/origin/HEAD        -> origin/master
 4   remotes/origin/master      3e2331d VT-d: suppress UR signaling for further desktop chipsets
 5   remotes/origin/stable-4.0  2692df2 compat/gnttab: Prevent infinite loop in compat code
 6   remotes/origin/stable-4.1  8995a94 page-alloc: scrub pages used by hypervisor upon freeing
 7   remotes/origin/stable-4.2  7bcdeb9 update Xen version to 4.2.5
 8   remotes/origin/stable-4.3  a153d8a update Xen version to 4.3.3
 9   remotes/origin/stable-4.4  be84c34 evtchn: check control block exists when using FIFO-based events
10   remotes/origin/staging     3e2331d VT-d: suppress UR signaling for further desktop chipsets
11   remotes/origin/staging-4.0 2692df2 compat/gnttab: Prevent infinite loop in compat code
12   remotes/origin/staging-4.1 8995a94 page-alloc: scrub pages used by hypervisor upon freeing
13   remotes/origin/staging-4.2 7bcdeb9 update Xen version to 4.2.5
14   remotes/origin/staging-4.3 a153d8a update Xen version to 4.3.3
15   remotes/origin/staging-4.4 be84c34 evtchn: check control block exists when using FIFO-based events

Checkout to "stable-4.4" and create a new branch named "netopt" and then checkout to it:

1 $ git checkout stable-4.4
2 Switched to branch ‘stable-4.4‘
3 $ git branch netopt
4 $ git checkout netopt
5 Switched to branch ‘net opt‘

1 $ sudo apt-get install build-essential
2 $ sudo apt-get install bcc bin86 gawk bridge-utils iproute libcurl3 libcurl4-openssl-dev bzip2 module-init-tools transfig tgif
3 $ sudo apt-get install texinfo texlive-latex-base texlive-latex-recommended texlive-fonts-extra texlive-fonts-recommended pciutils-dev mercurial
4 $ sudo apt-get install make gcc libc6-dev zlib1g-dev python python-dev python-twisted libncurses5-dev patch libvncserver-dev libsdl-dev libjpeg-dev
5 $ sudo apt-get install iasl libbz2-dev e2fslibs-dev git-core uuid-dev ocaml ocaml-findlib libx11-dev bison flex xz-utils libyajl-dev
6 $ sudo apt-get install gettext pandoc markdown python-dev
7 $ sudo apt-get install libperl-dev libgtk2.0-dev libaio-dev gcc-multilib

1 $ ./configure
2 $ make world
3 $ sudo make install

You can enable automatic start of Xen Project services on system startup:

1 $ sudo update-rc.d xencommons defaults 19 18
2 $ sudo update-rc.d xendomains defaults 21 20
3 $ sudo update-rc.d xen-watchdog defaults 22 23

By running "$ ls /etc/init.d/", you can find "xencommons", "xendomains" and "xen-watchdog". Note that Starting with Xen-4.3, "xend" is abandoned and replace by "xl".

You also need to make some changes to "/boot/grub/grub.cfg" to correctly boot to xen.gz:

1 $ sudo update-grub
2 $ sudo vim /boot/grub/grub.cfg

Modify the grub default option from "0" to "2": set default="2" (The option "2" normally locates the menuentry of "xen.gz")

1 $ sudo reboot

1 $ ln -s /usr/local/lib/libxenctrl.so.4.4 libxenctrl.so.4.4
2 $ sudo ldconfig

Then restart service xencommons:

1 $ sudo service xencommons start/restart

or:

1 $ sudo /etc/init.d/xencommons start/restart 

Congradulations! All steps are completed and now you can create a virtual machine by "sudo xl create **".
