Tried that for the last days, did not work either. The installation of squeeze and xen 4.0 was very easy indeed, only the pci-passthru does not work (tried 3 different computers with different hardware).Regarding to http://wiki.xensource.com/xenwiki/XenPCIpassthrough I used the options:
pciback.permissive pciback.hide=(09:00.0) pci=resource_alignment=09:00.0
xen-pciback.permissive xen-pciback.hide=(09:00.0) pci=resource_alignment=(09:00.0)
combined with "swiotlb=force" and "iommu=soft swiotlb=force" in the DomU
(the "official" wiki has no special entries for the current release 4.0, so I tried every combination...)
It just does not work, either the domU does not even start with some of the options, or the domU starts but the nic does not come up.

I am so far into several setups (plural) that I just does not want to give up and switch to vmware, so I
desperately ask again: Did anyone succeeded in installing xen 4 on _any_ Debian version _and_ got a passed through NIC working in the DomU?
