[-- Attachment #1.1: Type: text/plain, Size: 14134 bytes --]

Thanks Ian and Pasi, it took me much less time than I had thought to fix
drivers and I am able to see nic interfaces via ifconfig. I am yet to test
ping and other stuff. Had couple of questions

1. I used xe vm-param-clear uuid=<uuid-of-vm> param-name=other-config on
dom0 and rebooted domU assuming dom0 will get back pci device. It didn't. I
had to reboot dom0 in order to unhook pci device from domU. Is this the way
it is supposed to work?

2. Unrelated to pci passthrough, xen/stable code I downloaded doesn't seem
to have netfront drivers or any front drivers, doesn't it come by default
when you download from xen/stable?

Thanks
