I personally have a server with 2xDVB-S and 1xDVB-C and vdr headless with
MVP vomp hardware and vomp on Windows software clients. In addition, there
is a file server domain, a mail domain that receives faxes and sends them 
as mail, a DMU domain with web frontend for mail and vdr, as well as two
development domains. I think in the German forum http://www.ctserver.org
there are guys that also run Asterisk in a DomU. 

It's a matter of how much power you need and how much power you need. I use
a 4050e, 4GB RAM, 1,5TB data disks (offline when idle) and a 320GB laptop
drive for the system with ~35W, as it's mainly undervolted and underclocked.

       Cards with PCI addressing can be assigned to DomUs.  However, which
types of DomUs they can be assigned to, and whether or not they can be
assigned without requiring other things on the bus depend on your hardware
and the version of Xen you are running.  That said, most historical
discussion in this list will show that video processing and VOIP are not
good candidates for virtualizing (though I believe some people have had luck
doing so).  You should search/review the list's archives.  Hopefully someone
else can give you pointers, but now at least you have a response if they

I have played previously with VMWare and HyperV based solutions for
virtualization but not with Xen so forgive me if this question has an
obvious answer or has been asked before. Google has not provided me with an
obvious answer on this so...

I have a home pc with a tv tuner card in it which I was hoping that after
setting up Xen I could map that piece of hardware to a specific virtual
machine. Is this possible? There is also a similar scenario at work where I
would like to do the same for a PRI ISDN card and virtualize the pbx

Any ideas?
