PCI Passthrough - LENOVO TD340 VT-d enabled

[ciclonite]

Hi all,
I've installed the last version of proxmox on this server. I need to use the passthrough for a PCI parallel card with XP.
I've follow the instruction on wiki : https://pve.proxmox.com/wiki/Pci_passthrough but i've encountered a problem.
When i start the virtual machine i see this error:
kvm: -device pci-assign,host=0b:05.0,id=hostpci0,bus=pci.0,addr=0x10: Failed to assign irq for "hostpci0": Input/output error
kvm: -device pci-assign,host=0b:05.0,id=hostpci0,bus=pci.0,addr=0x10: Perhaps you are assigning a device that shares an IRQ with another device?

I've tried all the solution founded in this forum with no luck.
Any help will be greatly appreciated.

You'll have to provide more info if you want some feedback. I don't know the Lenovo hardware and if this system really supports vt-d.

At least provide output of:

$dmesg | grep -e DMAR -e IOMMU
$lspci -vv #(only the part of the device which you want to passthrough)
$lspci -vv  | grep IRQ

According to your output of lspci, you tried already to passthrough the pci device (pci-stub driver is in use). Maybe you can also post the output of both lspci commands after a fresh system restart without trying to passthrough the pci device.

I can only try to give some hints because I also don't have alot of knowlege about IRQ handling. But the device you are trying to passthrough is assigned to IRQ 255. It seems that IRQ 255 is assigned if the device doesn't need an IRQ or no IRQ is available (this is a article which gives some basic information about IRQ 255, but I don't know if this report is still valid). Maybe you can check your bios for settings like "PnP OS" or something related to IRQ handling. Also as mentioned above, please post output of lspci commands after fresh reboot (without trying to passthrough any pci device).

You can also try kernel 3.10 and pci-vfio. But you'll have to build the packages on your own or wait for the pve-test repo to be updated.

Hi,
Thanks for reply.
Here the post after a fresh reboot and without the passthrough enabled.

I want to try another parallel card (for example pcie).
any news will be reported here.
Thanks a lot.
