Below are instructions for building your own Archivematica virtual appliance. This allows you to create intermediate or branch releases to test and use your own modifications. 

==Requirements==
*Ubuntu server 10.04
*vmbuilder requires KVM which requires a virt compatible processor however, you do not need virt support for vmbuilder
*At least 2GB of ram

==Software Requirements==
subversion (SVN)
<pre>sudo apt-get install subversion
</pre>

vmbuilder 
<pre>sudo apt-get install ubuntu-vm-builder
</pre>

A local apt-proxy. We recomend apt-cacher-ng.
<pre>sudo aptitude install apt-cacher-ng
sudo gedit /etc/apt-cacher-ng/acng.conf
</pre>
change the port.. whatever its set to..(3142 defuault) to 9999
Restart the service for changes to take effect.
<pre>sudo /etc/init.d/apt-cacher-ng restart
</pre>

==Pre Build==
1. check out the source
<pre>svn checkout http://archivematica.googlecode.com/svn/trunk/ archivematica-read-only</pre>

2. Run the build script:
This script will set the vmbuilder execscript to archivematica.sh and create the selected type VM.
Note the rootSize is the size of the vm disk to build in MB.
<pre> 
cd archivematica-read-only
</pre>

==Post Build==
1. boot your virtual machine.  For KVM its under ubuntu-kvm, for other examples please see [[Virtual_appliance_instructions]].
<pre>kvm -m 528 -smp 1 -drive file=disk0.qcow2 </pre>

2. From inside the machine open a terminal and run the post build script:
This will create the necessary databases, and tables.
<pre>
cd ~/postBuildScripts
./postBuildRun.sh
</pre>

3. Open firefox and navigate to http://localhost, go through the qubit installer for the database settings all defaults will work.

4. Aside from some icon placement you now have a fully functional version of archivematica!

==Create a .raw file==
1. A raw file can be used to run the virtual appliance directly from a USB key or to install it directly on dedicated hardware without a virtualization layer.

2. after running vmbuilder you will be left with a qcow2 image. Run the following command:
<pre>kvm-img convert -f qcow2 -O raw disk0.qcow2 archivematica.raw</pre>

3. See [[Build a Live USB disk]] for instructions on using the .raw file to create a bootable USB key version of Archivematica
