Hi Konrad,
Thanks, the problem solved when I pass in 'iommu=soft' in the PV guests. Could
you elaborate on the link between this option and the problem?
And this option also raised another minor issue. For example, I have 4 domus,
and the PCI passthru situation as below:
Domu_name passthru_pci_number_in_dom0
1 04:00.0 04:00.1
2 02:00.0 02:00.1
3 01:00.1
4 <none>
I passed in 'iommu=soft' in 1,2,3 domu. The order I should boot the domus is
1,2,3,4. Otherwise, the domu might fail to boot due to the error:
Pciback 0000:04:00.1: device has been assigned to another domain! Over-writing
the ownership, but beware.
Any idea about this?
Thanks,
Huaxiang

It would be really helpful if you did provide some logs. Did you also pass in
'iommu=soft' in the PV guest?
The NICs I've tried it on were .. hmm, I don't have the list in front of me,
but I do remember
these modules: e1000, igb, ixgb, tg3, sky2, and r8169.
