=====Installing Xen on a Debian Wheezy Host=====
All information in the guide was taken from the following link:
[[http://wiki.xenproject.org/wiki/Xen_Project_Beginners_Guide|XenProject PV Guest tutorial]]

====Enable Virtualization Support in BIOS====
The virtualization option appears differently in different BIOS builds but generally it is referred to as “Enable Virtualisation Technology” or “Enable Intel VT” for Intel chipsets, however in some cases it can be listed as “Vanderpool Technology”. Oftentimes this option can be found under the “Advanced Chipset Features” menu in the BIOS. Similar also for AMD. 

====Install Debian====
Download the netinst image from the following link:
http://cdimage.debian.org/debian-cd/current/amd64/iso-cd/

Partition the disk as follows:
<code>
   sda1 - /boot 250MB
   sda2 - / 15GB
   sda3 - swap
   sda4 - reserved for LVM
</code>

Be sure to install sudo, vim, and tcpdump. Add the user to sudo group.
<code>
   apt-get install sudo, vim, tcpdump
   usermod -a -G sudo <user>
</code>

====Configure LVM for Guest Storage====
<code>
   apt-get install lvm2
   pvcreate /dev/sda4
   vgcreate vg0 /dev/sda4
</code>

====Set up Linux bridge for guest networking====
<code>
   apt-get install bridge-utils
</code>
Edit ''/etc/network/interfaces'' to look as follows IOT create a bridge:
<code>
    auto lo
    iface lo inet loopback

    auto eth0
    iface eth0 inet manual
    
    auto xenbr0
    iface xenbr0 inet dhcp
        bridge_ports eth0
</code>
This is the same as doing:
<code>
   brctl addbr xenbr0
   brctl addif xenbr0 eth0
   dhclient xenbr0
</code>

====Install the Xen Hypervisor====
Install the hypervisor and xen-tools (xm).\\
Once Complete, configure grub to boot the hypervisor before the debian OS.
<code>
   apt-get install xen-linux-system xen-tools
   dpkg-divert --divert /etc/grub.d/08_linux_xen --rename /etc/grub.d/20_linux_xen
   update-grub
</code>
   
====Create and Manage Guests====
Update the xen config file ''/etc/xen-tools/xen-tools.conf'' prior to creating vm's on the cmd line. Also, be sure to uncomment line 146: ''#  (network-script network-bridge)'' of ''/etc/xen/xend-confix.sxp''.

After updating xen-tools.conf with the config posted below, create and connect to a new guest using xen-create-image.

<code>
  xen-create-image --hostname=tutorial-pv-guest \
  --vcpus=2 \
  --pygrub

  xm create -c /etc/xen/tutorial-pv-guest.cfg
  #xm create /etc/xen/tutorial-pv-guest.cfg && xm console tutorial-pv-guest
  xm shutdown tutorial-pv-guest
</code>

<file txt xen-tools.conf>
test
</file>
