Hi Jeremy, Each system vm must have a public IP and a private IP.
public IP of console proxy VM: access vm console from client private IP of console proxy VM: establish vnc or websocket connection to hypervisor for VM console. public IP of secondary storage VM: download template or volume from client private IP of secondary storage VM: connect to secondary storage and mount it in SSVM If storage network is different from management network, SSVM will have an extra storage IP. -Wei On Mon, 28 Feb 2022 at 11:56, Jeremy Hansen <jer...@skidrow.la.invalid> wrote: > I can cut out IPs to use for the system vm’s, but why do they need two > interfaces?
