+== Building A VM host ==
+External3 was rebuilt into a VM host. 
+
+{{{
+BASE OS: Ubunut 11.04
+Bridge: Open V Switch
+Emulator: KVM
+}}}
+
+=== Building the Host ===
+It was built using the following steps:
+
+ 1. Install Ubuntu 11.04 from CD (with stock kernel): Had to switch to version 11.04 for kernel compatibly with openvswitch. 
+    The running Kernel Version is: 
+    {{{
+    root@external3:~# uname -r
+    2.6.38-8-server
+    root@external3:~# uname -a
+    Linux external3 2.6.38-8-server #42-Ubuntu SMP Mon Apr 11 03:49:04 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
+    }}}
+ 1. run kvm-ok.
+    You might need to run 
+    {{{
+    apt-get install cpu-checker
+    }}}
+    Check for a message like this one: 
+    {{{
+    INFO: /dev/kvm does not exist
+    HINT:   sudo modprobe kvm_intel
+    INFO: Your CPU supports KVM extensions
+    INFO: KVM (vmx) is disabled by your BIOS
+    HINT: Enter your BIOS setup and enable Virtualization Technology (VT),
+          and then hard poweroff/poweron your system
+    KVM acceleration can NOT be used
+    }}}
+    If disabled, you will need to enter the bios to enable it.
+ 1. Install the openvswitch packages. Do not use the Ubuntu repositories since the install the incorrect versions of the package, instead download the 
+    packages that match your kernel version from [http://openvswitch.org/releases/binaries/1.2.2.10448/natty_amd64/ here]
+    I downloaded:
+    {{{
+    openvswitch-datapath-module-2.6.38-8-server_1.2.2.10448_amd64.deb
+    openvswitch-common_1.2.2.10448_amd64.deb
+    openvswitch-switch_1.2.2.10448_amd64.deb
+    openvswitch-brcompat_1.2.2.10448_amd64.deb
+    }}}
+    and then Installed them in that order with "dpkg -i". 
+ 1. Once these are installed you can start/restart the openvswitch dameon
+    {{{
+    /etc/init.d/openvswitch-switch
+    }}}
+ 1. The readme refrenced [http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob_plain;f=INSTALL.KVM;hb=HEAD here] recomends installing
+    the uml utilities, I didn't need them but I installed them any way.
+    {{{
+    apt-get install uml-utilities
+    }}}
+ 1. After these components were installed I added a bridge and got it an address:
+    {{{
+    ovs-vsctl add-br br0
+    ovs-vsctl add-port br0 eth0
+    ifconfig eth0 up
+    dhclient br0
+    }}}
+    In retrospect I could have used brctl once I brought up the compatibly daemon.
+ 1. As referenced in the brcompat documentation [http://openvswitch.org/cgi-bin/gitweb.cgi?p=openvswitch;a=blob_plain;f=INSTALL.bridge;hb=HEAD here], 
+    I took these steps to bring up the bridge daemon. According to the kvm documentation,
+    you don't really need brcompat however virtmanager fails to build VM's if you don't bring up the daemon. '''NOTE''' you do not need, and should not install bridge-utils, 
+    it will load the bridge modules and create conflicts with openvswitch_mod.
+    {{{
+    insmod /lib/modules/2.6.38-8-server/kernel/brcompat_mod.ko
+    ovs-brcompatd --pidfile --detach
+    }}}
+ 1. Now we're ready to install the KVM packages documented [https://help.ubuntu.com/community/KVM/Installation here], all but the bridge-utils:
+    {{{
+    sudo apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder virt-manager
+    }}}
+ 1. From here we should be able to fire up virt-manager and build a VM.
+
+----
+=== Building the client OS ===
+
+ 1. copy the install iso to some directory (I used /root)
+    {{{
+    wget http://mirrors.mit.edu/ubuntu-releases/11.10/ubuntu-11.10-server-amd64.iso
+    }}}
+ 1. Start up virt-manager (you will probably need x11 forwarding enabled). Click on the new button.
+    [[Image(virtmanager.jpg)]]
+ 1. When you're setting the params make sure to specify bridging as the networking method.
+    [[Image(virtmannet.jpg)]]
+ 1. When you get to the ubuntu install screen, Rember to press f4 on the ubuntu install menu to get the virtual machine version.
