It seems pointless to me for the user to have to explictly destroy the VM. Once the bhyve process exits, I doesn't seem that I can use the VM again anyways. To run the VM again, I seem to need to call: -> bhyvectl to destroy the VM -> bhyveload to load -> bhyve to run the VM Aryeh has pointed out to me that it is the responsibility of the user to explictly destroy and tap and bridge devices used by the bhyve process after it exits. Is this right? What if I have a single bridge0 device, and 10 tap devices, one per VM? If one VM exits and needs to be restarted, do I need to tear down all the taps and bridge? -- Craig
