Disclaimer
I'm not even going to pretend that I thought of any of this section. The folks over at Xen Hosting have a great setup, and I've taken almost all of this from thier model.
Networking Infrastructure
We have a single domain XenKibbutz.com that is used for hosting this website, client accounts, as well as allowing client console access to thier virtual machines.
Client Access
Each client has a unique username, and their system can be accessed via:
$username.xenkibbutz.comTo allow users to manage their Xen system there is a simple shell which is described in the support section. This shell can be accessed via:
ssh -i #keyfile $user@$user.console.xenkibbutz.comThis shell allows access to the console of the guest system even if the networking of the VM is down. (Perhaps do to a broken firewall, or prior to setup.)
SSH access to the console is only available using public key authentication. Please mail Theron if you have lost your key.
Networking Details
Each Xen guest is supplied with a single IP address by default, however, if more than the one is needed, let Theron know, and he'll try and work something out for you.
Remember, support is available even if you lose access to your systems network interface.
