I'm looking at the drivers, and it seems like if the VF sends a E1000_VF_SET_VLAN message specifying a particular VLAN ID then the PF will call igb_set_vf_vlan_strip(adapter, vf, true) which will set the switch to strip the vlan tag. Am I reading this right? In the case where the host puts the guests into separate VLANs without their knowledge I can see how stripping the VLAN ID might make sense. But if a guest explicitly creates a vlan device they're expecting a VLAN-tagged message to arrive. If the switch strips off the VLAN tag then that message is going to seem like it's coming in on the regular device, not the VLAN device.
