[Xen-users] Trouble enabling PCI passthrough in xen HVM

[arvind viswanathan <arvind.viswanathan@xxxxxxxxx>]

Hi,

I am using opensuse as my dome and I tried to make a NIC card work in PCI passthrough. pciback is installed as a module in this kernel. I unbound all the NIC's from dom0 driver and bound them to PCI back.

I then modified the domU config file to include the pci device. When the system started booting up, I NICs were recognized however they failed to attach. This is the message I got,

em1: <Intel(R) PRO/1000 Network Connection 7.0.0> port 0xc140-0xc15f mem 0xf3020                    000-0xf303ffff,0xf3040000-0xf305ffff irq 37 at device 5.0 on pci0

em1: Reserved 0x20000 bytes for rid 0x10 type 3 at 0xf3020000

em1: Setup MSIX failure

ioapic0: routing intpin 37 (PCI IRQ 37) to vector 52

em1: [FILTER]

em1: bpf attached

em1: Ethernet address: 00:15:17:ae:a1:f1

I am not sure how to recover from this problem. Any suggestion to debug this would be very helpful.

Thanks
