Abstract:
A virtual-machine-based system provides a control-transfer mechanism to invoke a user-mode application handler from existing virtual hardware directly, without going through an operating system kernel running in the virtual machine. A virtual machine monitor calls directly to the guest user-mode handler and the handler transfers control back to the virtual machine monitor, without involving the guest operating system.
