Hi
Thank you for the patch.
vhost-blk didn't spark enough interest to be reviewed and merged into
the upstream and the code is not present here.
I have forwarded your patch to relevant openvz kernel mailing list.

8 queues is too few, for example vhost-scsi have 128.
Increase to 32 queues max, as we do not want to eat too much
memory. As for performance, 32 queues will top around 3M iops,
which should be fine for almost all cases
