Ensure that VF link state is set appropriately. The following "ip"
command allows you to control whether the VF link follows the physical
function link state, is always up, or is forced down (your system might
be configured for the "down" state):
ip link set <pf> vf <vf_index> state auto|enable|disable
Try enabling "auto" or "enable" on the host and see if that helps.
