We keep the QEMU/libvirt default which is to honor client's request. Which is in case of novnc by default "shared", other common clients like vncviewer default to "disconnect" I wonder if anyone is using the shared behavior or we should disallow it. Or make it optional, which is nice but as always comes with a price of development time. > > If you launch a client that initiates a shared connection to the console > then existing connections will stay open.
