[openstack-dev] [nova][neutron] Boundary between Nova and Neutron involvement in network setup?

Hi Neil,

@Neil, could you please also add VIF_TYPE_VHOSTUSER in your spec (as I commented on it)? There has been active VHOSTUSER discuss in JUNO nova BP, and it's the same usefulness as VIF_TYPE_TAP.

Best Regards

Many thanks, Kevin.  I see this now too, as I've just written more fully
in my response to Ian.

Based on your and others' insight, I've revised and reuploaded my
VIF_TYPE_TAP spec, and hope it's a lot clearer now.
