Compiling Xen from source using dpkg

Compiling and installing software from source is used by developers a lot. So using ./configure , make, make install is something we all are well aware of but this is a very messy way to do so because when you uninstall the program it may leave some dependency files in the system or might not work properly when again installed.

I observed this case a lot of times when I use make install. Even sometimes a tried removing extra programs/dependencies manually.
So now I will write about a clean and very good way of installing Xen by source.

Download Xen sourcecode from git.

And run these commands:
#cd xen
#./configure –prefix=/usr
#make
#make debball
#dpkg -i dist/xen-upstream-XXXX

And whenever you want to uninstall it just use.

#dpkg -r xen-upstream
#apt-get purge xen-upstream

And yes you don’t have to worry about any of the dependencies as dpkg will take care of it. 🙂

Ubuntu 14.04 with Xen and Virtual Machine Manager

Installation of Xen Hypervisor and Virtual Manager on Ubuntu 14.04.1

1. Install Ubuntu 14.04.1 and more importantly enable virtualization in boot options
You can get the installation steps from Ubuntu official site.

2. Open terminal and install xen hypervisor
sudo apt-get install xen-hypervisor-amd64
(installing 64 bit hypervisor runs on 32 bit dom0 and also creates 64 bit domU)

Then reboot (you don’t have to update grub)
sudo reboot

3. After rebooting just to check if Xen booted with Linux
sudo xl info

sudo apt-get install bridge-utils

4. Open  /etc/network/interfaces and change it

auto lo
iface lo inet loopback

auto xenbr0
iface xenbr0 inet dhcp
    bridge_ports eth0

auto eth0
iface eth0 inet manual

Then restart network manager
sudo ifdown eth0 && sudo ifup xenbr0 && sudo ifup eth0

5. Now install Virtual Machine Manager
sudo apt-get install virt-manager

Now restart your system open virtual machine manager and add connection Xen.
Then start creating your domU’s.
