It is a good time to start over. Your old virtual devices and community installer are on the old Groovy platform that will be retired soon. Possible by the end of September.
The attached shows a couple ways to create new Virtual Edge Devices including switches. Basically you follow one of the attached links, subscribe to that person’s driver and you can easily create virtual devices from your mobile app. These are part of the new system and will continue to work after the transition.
