    摘要: A system, method, and program product is provided that has a virtualized environment provided by a hypervisor. In the virtualized environment, one or more guest operating systems operate simultaneously with a privileged operating system. One of the guest operating systems identifies a device software update, such as a device driver or firmware update, corresponding to a hardware device that is attached to the computer system. The hypervisor is used to notify the privileged operating system of the device software update. When the privileged operating system is notified of the update, the privileged operating system uses one or more techniques to deny the guest operating systems access to the device. The privileged operating system then updates the device software update. After the device software update has been applied, the privileged operating system resumes access between the guest operating systems and the hardware device.
