Facilitating Power Management of a Hardware Device by a Virtual Machine

A method comprising:

• receiving, by a first hypervisor supporting a first virtual machine, a first request from the first virtual machine indicating a target power mode for a target hardware device assigned to the first virtual machine;
• and
• in response to receiving the first request, transmitting, by the first hypervisor, a second request indicating the target power mode for the target hardware device to a second hypervisor, the second hypervisor being configured to forward the second request to a second virtual machine, the second virtual machine being configured to cause the target hardware device to enter the target power mode in response to receiving the second request.

A non-transitory computer-readable medium comprising instructions that are executable by a processor for causing the processor to perform operations comprising:

• receiving, by a first hypervisor supporting a first virtual machine, a first request from the first virtual machine indicating a target power mode for a target hardware device assigned to the first virtual machine;
• and
• in response to receiving the first request, transmitting, by the first hypervisor, a second request indicating the target power mode for the target hardware device to a second hypervisor, the second hypervisor being configured to forward the second request to a second virtual machine, the second virtual machine being configured to cause the target hardware device to enter the target power mode in response to receiving the second request.
