It seems more likely that they've put in a software device model of NVME as a replacement for the BlkBack software device model that the BlkFront driver talked to. Not much different than the software e1000 NIC that xen/qemu already supports.
That said, with their virtualizable Annapurna wonder-NIC, they could be doing it in "hardware", though even in that case a reasonable part of the device model would be software, just running on a NPU, not a CPU.

Hopefully Amazon will disclose more details.
