Asterisknow with XEN

Hi all.
I have *now running in a virtual machine xen (Centos 5.5 as dom0).

I found a TDM400P and I want to know if asterisknow will detected this or should I do something else or reinstall. Sometimes there are issues with hardware and virtual machine…

I have to get a analog line and to buy a fxs module, and I wish to know if this can be done before expend 60$/

Thanks

Real time applications like VoIP don’t work well with VMs. I don’t know about Xen, but normally non-standard hardware cannot be virtualized.
