Hi Ran, >echo 63 > /sys/bus/pci/devices/0000\:05\:00.0/max_vfs >I'm getting 63 pfs in lspci,
You mean VFs and not pfs, I assume. I tried something similar but with qemu cli, not virsh, using PCU passtrhough (-device pci-assign…) and i40e, but using igb_uio. I tried it with one VF and it worked OK. Do you see any errors in the kernel log (dmesg)?

Libvirt is not able to bring up the guest, and exit with internal error. I assume that the vlan/mac initialization which is working well, when the PF is assigned to ixgbe.k does not work when bound to igb_uio. Is this an igb_uio issue or libvirt ? is there a workaround for this ?
