Abstract
The updating of virtual machines. A task broker schedules update tasks for multiple virtual machines on the host machine. As each update task is to be performed, if the virtual machine is not currently running, as might be the case for a personal virtual machine, the virtual machine is caused to begin running to allow the update task to be performed on the virtual machine. Also, a pooled virtual machine is updated by copying information from the old virtual hard drive to a location to allow the information to be preserved as the master image is updated. After the update is completed, the virtual machine is formed, associated with the new virtual hard drive, and copied back to the virtual machine.
