I have attempted to use Xen on FC5 for my Asterisk setup as well.  This 
is for my home office, so very few extensions, so I thought a Dell 
Optiplex PIII 550Mhz should handle this nicely.

In my setup I have a single Digium X101P PCI card to provide FXO access.

The problem I've run into is the FC5 kernels for Xen do NOT allow the 
PCI hiding capability, it is not compiled into the Dom0 and DomU Fedora 
provided kernels.  Because of this, I cannot get access to my Digium 
card in the DomU...so I'm stuck.  I don't really want to compile my own 
kernel...just for this.

If I could get past this issue, I'd be running Asterisk in a Xen DomU 
domain.
