Hi,
Nothing works yet.
In the /var/log/xen/xend.log I saw:

Subject: pci-attach - HOWTO
Hi,
I tried to attach passrough io device to domU, the command (ended successfully
in dom0), but when I entered the domU and typed the "lspci" command I didn't
see the new device, although the dom0 removed it from the
"pci-list-assignable-devices".
When I tried to detach it from the domU, the detach command returned with
timeout error.
What did I miss? perhaps I need to do something in the domU (the hotplug
feature? do I need to enter it manually? if yes How?)
Thanks in advanced, Erez
