Re: [Xen-users] Example PCI hiding in dom0 and direct access in domU

[Brian McEntire <brian.mcentire@xxxxxxxxx>]

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.

Thanks!

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