hi,
i cant hide pci devices in dom0. i boot my dom0 simply with
pciback.hide=(00:11.5), but this device is allways visible. also i cant
passtrough this to domU - no errors but invisible in domU.
in this case the 00:11.5 is a onboard soundcard on a testmachine. later i want
passtrough a isdn card on a productive machine with the same setup.
on dom0 i see:
