Thanks for the tip. You were right, after hiding the PCI card from DOM0, I was then able to start another Dom0 VM and lspci showed only the Digium PCI card.

Unfortunately, even then, Asterisk core dumps when I try to start it. One of the messages from the dump/oops (?) is "General Protection Fault".

I'll probably give up trying to get Asterisk to run in a VM since it is running okay in domain0. But if anyone has made this work (with Zaptel/wctdm modules and the Digium TDM PCI card,) I'd love to hear about it.

Have you tried usind a Dom0 kernel for the virtual machine? In my
opinion DomU kernels don't support real hardware access.
