hi,
i want to enable vt-d in xen, but meet an error.
            at first, i do all things as /xen-unstable.hg/docs/misc/vtd.txt says.
grub : kernel   /boot/xen-3.5.gz   iommu=passthrough
module     /boot/vmlinuz-2.6.18.8-xen   pciback.hide=(02:00.0)(02:00.1)
hvm.conf :pci=['02:00.0','02:00.1']
                (02:00.0    02:00.1  are my nics)

after reboot,there is no these two nics in 'ifconfig -a'
and when i start hvm, it is block on "PNP: PS/2 controller........"
at this time, i use 'xm pci-list hvm' and got messages 
0x04....
0x05.....
that seems pci devices have been passed to hvm.


but when i changed two nics to another pci device, it can be assigned to hvm successfully.
grub : kernel   /boot/xen-3.5.gz   iommu=passthrough
module     /boot/vmlinuz-2.6.18.8-xen   pciback.hide=(00:14.1)
hvm.conf :pci=['00:14.1']
(00:14.1  GPIO)



any one can help me?thank you for advance!
