+1 on adding this support. Do you intend to keep the implementation similar to how the Nexus1000v support works (or will after it's fixed)? I'd prefer that they are at feature parity, given that the 1kv is really just a replacement for the VMware DVS that gives operators a nice CLI to work against. > > [1] CLOUDSTACK-657 - "VMware vNetwork Distributed Virtual Switch support in > CloudStack" > > > > Regards, > > Sateesh > > > > >
