I am experimenting with the os-vif library and stumbled upon this new
VIF type called VIFHostDevice. I have few general queries. TIA.

1. How do I create ports with VIF_type as VIFHostDevice? Looking for
the CLI command options.

2. Say, I have OVS running completely on x86 host(no datapath or flow offload to
 NIC) as the networking mechanism and a SRIOV capable NIC(for existence of
VF representors that will be added to the OVS bridge). Can I still
launch instances with VIF_type as VIFHostDevice?

3. I want to use Security Groups using OVS+Conntrack as the mechanism.
Can I apply SG rules on the ports of type VIFHostDevice using the
above mechanism?

PS: I am still trying to understand this. Hence, I might get my
premises wrong in the above questions. Will appreciate a detailed
