So I am using cloudstack with esxi as the hypervisor. I am also using advanced network using vlans for network isolation. As such cloudstack has vmware create a new port group for each network. If I wanted to clean up the "unused" port groups can I simply delete them from vmware, or would I need to do something extra in cloudstack as well? Or is it even necessary to delete them or will cloudstack reuse the unused port groups if necessary? Hopefully this makes sense.
