xm pci-list-assignable-devices

You should able to see all pci back devices.

Also I notice that I was not able to pci pass through successfully untill I disable the firewire device from bios.

If you have NIC working, let me know.

So much for saying the e1000 works -- I've now tried to test again and
it seems to freeze my dom0 entirely. No logs written or output to
screen. Manual reboot is the only fix.

the freeze only occurrs when a machine with a PCI passthrough is active.
An example is trying to add an IP to the passed through port.

Does anyone have this running stable?
