What are the requirements for High Availability in a VirtualBox backend?
High Availability for a VirtualBox virtualization platform would require at least 2 VirtualBox hosts. In the event that one VirtualBox server goes down, all existing desktop sessions would be terminated. Then the terminated sessions would be restarted on the remaining VirtualBox server(s) as they are requested by users, as long as there is sufficient memory available.
High Availability for The VDI Core, Sun Ray, and MySQL requires a Primary node, and 2 Secondary nodes. See Supported Configurations for detailed information about the hardware configurations that support this type of redundancy.
