Once installed and configured you can create a new Xen instance in a matter of minutes. Each new Xen domain will be complete with:
* All networking details setup, with either multiple static IP addresses or DHCP. * An installation of OpenSSH. * An arbitary set of partitions.
Your new instance will be completed by having the user accounts from your guest system copied over, and you may optionally boot the image as soon as it has been created.
