Lenovo M720q Tiny and PCIe Network Card

[spetrillo]

Hello all,

Does anyone have a 4 port network card in the PCIe slot of the M720q and are using PCI passthrough? I cannot seem to get mine to work. Everytime I try to start up the VM I want to use NIC passthrough on it hangs the VM and then the PVE all together. I have validated IOMMU is enabled, I have blacklisted the NIC driver. I just cannot get past this. I am curious if there are some who have gotten this to work, with this hardware config.

Thanks,
Steve

It's a late response, but your problems were almost certainly due to the fact that all NICs were in the same IOMMU group.

This hint helped guide me in the right direction for my m720q, i appreciate it!
