Transitioning virtual machines to an inactive state
View Patent ↗An example computer system is provided that utilizes an agent to operate autonomously in transitioning virtual machines between an active state and an inactive state. In an implementation, a processor executes instructions to cause a computer system to implement a virtual machine communication interface, and to host a virtual machine. In some examples, the processor executes instructions to cause the computer system to utilize an agent to operate autonomously in transitioning the virtual machine from an active state to an inactive state after a period of inactivity. In other examples, the processor may execute instructions to cause the computer system to transition the virtual machine from the inactive state back to the active state upon receiving a data packet targeted for the inactive virtual machine.
