Hi Paolo,
vhost-user-blk:
We have an initial implementation in our SPDK QEMU repo. Changpeng Liu (added)
will be sending this to the QEMU mailing list shortly. If you are interested
in viewing it
before it hits the mailing list, you can take a look at the patch here:
https://github.com/spdk/qemu/commit/db2fcb0f5002c3d195e756eab07bd976ccf6e7c8
virtio-blk poll-mode driver:
Yes - this is part of our plan as well - once we have virtio-scsi in place,
adding virtio-blk
will be relatively straightforward.
Thanks,
-Jim
