Post deploying the image on VM, you just need to turn it ON, after that go to console/CLI and you need to run "setup" command to complete the initial configuration of vSZ (vSZ type, port config, IP config)
Please check what is the status when you run "show service" command.
Web GUI will not be accessible until "web" service is online.
