Patent abstract
A processing device receives a first request from a virtual machine to register a memory region to a hardware device. The processing device generates a first key for the memory region, wherein the memory region is not registered to the hardware device. The processing device generates a second key for a shared memory pool that is pinned and registered to the hardware device. The processing device generates a mapping of the first key to the second key. The processing device sends a response to the virtual machine that the memory region has been registered to the hardware device, the notification comprising the first key.
