Hi List,
I am having problems to do pci passthrough to a network card without using VT-d. The card is present in the guest but with a different model (Intel Corporation 82801I Gigabit Ethernet Controller (rev 2)) and it does not work. The qemu line that I used is:
./devel/bin/qemu-system-x86_64 -hda ./dm.img -m 256 -pcidevice host=00:19.0,dma=none -net none
Before running qemu I did
echo "8086 294c" > /sys/bus/pci/drivers/pci-stub/new_id
echo 0000:00:19.0 > /sys/bus/pci/drivers/e1000e/unbind
echo 0000:00:19.0 > /sys/bus/pci/drivers/pci-stub/bind
This is the lspci -tv output

I am getting the following error in host dmesg

It does work if I enable VT-d, even though the network card is recognized with a different model. However, I need this to work without VT-d. Which could be the problem here? Is this supported?
Thanks a lot,
Pablo

One update on this. I disabled VT-d from the BIOS and now I am not getting the DMAR error messages in dmesg, but the board still does not work on the guest. Any help is welcomed.

Are you expecting this to work using the 1:1 mapping for direct device assignment? I use a similar setup (e.g. dma=none and no VT-d) but a different NIC (Intel 82598 10G) and a different driver (ixgbe). I see the same messages, but also don't get the device to work in the guest (while it does work in the host OS). In fact I don't get any errors on the guest side, so it is hard to track what is wrong. No I/O is happening. The guest cannot not transmit/receive any packets to/from those NICs. The interface packet counters stay at 0.
I see an error in QEMU saying invalid memtype, and it also seems to have trouble assigning IRQs. assigned_dev_enabled_msix() fails with Invalid Argument, but on the guest side I can see that MSI-X is configured properly under /proc/interrupts.
I use the latest KVM 2.6.30 tree in both host OS and guest OS.

Hi Anna,
>Are you expecting this to work using the 1:1 mapping for direct device assignment?
Actually, I want to use the current qemu implementation for this. AFAIK from the code seems that qemu mmaps the device memory into the qemu pci subsystem memory space. Is this correct?
>In fact I don't get any errors on the guest side, so it is hard to track what is wrong.
In the guest I am getting an error in dmesg saying "Detected Tx Unit Hang"
>I see an error in QEMU saying invalid memtype, and it also seems to have trouble assigning IRQs.
The only error I am seeing in qemu is
assigned_dev_iomem_map: e_phys=f2020000 r_virt=0x7f95bca9a000 type=0 len=00020000 region_num=0
BUG: kvm_destroy_phys_mem: invalid parameters (slot=-1)
Regards,
Pablo
