Hi Rami,
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.
