John Levon, Swapnil, and I are implementing the server part in libvfio-user (formerly known as MUSER). We also have a mailing list now: https://lists.nongnu.org/mailman/listinfo/libvfio-user-devel. We've been working on integrating the two parts. > > Finally, Changpeng is implementing an NVMe controller in SPDK.

If not ready will change this patchset to state "awaiting upstream". I.e not ready until QEMU is ready
