In one implementation, a method of sharing a physical device between multiple virtual machines is provided. The method includes receiving, from a first virtual machine, a request to access a physical device of a computing device. The method also includes determining, by a processing device, whether the physical device of the computing device is available in view of power state information associated with the physical device of the computing device. The method further includes in response to determining that the physical device of the computing device is available, assigning the physical device to the first virtual machine.
