Install the Xen hypervisor tools and kernel:

<code>
aptitude -y install xen-hypervisor-amd64
</code>

Download the Ubuntu 14.04 / trusty kernels to do a netboot off of, the one with the most recent updates [[http://ubuntu.cs.utah.edu/ubuntu/dists/trusty-updates/main/installer-amd64/current/images/netboot/xen/|here]].

Sample configuration, using a netboot kernel:

<code>
kernel        = '/etc/xen/kernels/trusty-updates/vmlinuz'
ramdisk       = '/etc/xen/kernels/trusty-updates/initrd.gz'
memory  = 4096
vcpus   = 4
name    = 'ubuntu-xen1'
disk    = ['phy:/dev/xvg/ubuntu-xen1-root,xvda,rw','phy:/dev/xvg/ubuntu-xen1-swap,xvdb,rw']
vif     = ['bridge=br0']
</code>

Once the installation is finished, disable the ''kernel'' and ''ramdisk'' settings, and set the ''bootloader'' to pygrub:

<code>
bootloader = 'pygrub'
# kernel        = '/etc/xen/kernels/trusty-updates/vmlinuz'
# ramdisk       = '/etc/xen/kernels/trusty-updates/initrd.gz'
</code>
