Re: [Xen-users] Xen and Zaptel PCI cards on DomU

[Jason <xen@xxxxxxxxxxxxxxxxx>]

I have been able to get the cheapy fxo cards detected compiled and running, but 
I have some nasty
issues using it. It seems that those cards are really IRQ happy and when Im 
using the card, the
rest of the box becomes almost unresponsive.

To compile the code, just build it in your domain0 and set KVERS=2.6.16-xenU 
(or whatever your
kernel version is). Then just copy the modules into your domU.
