In the following demo, Dor is running 4 different OSv base virtual appliances on his laptop:
Each virtual appliance is a full–blown VM, each with a pre-integrated cloud application, and each launched without terminating the others.
As you can see, application startup time takes between sub-second (Redis) to a few seconds (Cassandra) depending on the application. The hypervisor plus OS part of the boot time is less than a second for all cases.
