Xen, Asterisk, and a TDM400P

When you throw them all together, you have a nice virtualised VoIP server with excellent support for up to 4 FXO or 4 FXS modules per card! Although this seems quite simple, giving direct hardware access to a virtualised machine is not the most simple thing to do. This being the case, I’ve documented how to do it over here.

Let me know if there’s more that should be added!
