US Patent 9223596 Virtual machine fast provisioning based on dynamic criterion

Disclosed herein are methods and systems for reducing the loading time of virtual machines. A virtual machine is booted on a virtual machine host. The machine continues to initialize until it has reached a ready-state. The machine is then paused on the virtual machine host. A request for the virtual machine may then be received from a client. The machine is then resumed on the virtual machine host and a notification may be sent to the client stating that the machine is ready.
