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)?

I'm creating the vfs, while the pf is bound to igb_uio:
echo 63 > /sys/bus/pci/devices/0000\:05\:00.0/max_vfs
I'm getting 63 pfs in lspci, but when i try to load the vm:
virsh create mini1.xml
error: Failed to create domain from mini1.xml
error: An error occurred, but the cause is unknown
in the dpdk manual, it's refering to qemu, so I probably assume that the libvirt try to initialize the VF mac and vlan, but this is not supported by the igb_uio ?
it works well when ixgbe.ko is bound.

I'm having trouble trying to build a scenario were the host has the PF bound to igb_uio, and working with dpdk application, together with sr-iov VFs passthrough to guest machines.
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 ?
