[PATCH 0/2] block/export: add vhost-user-blk multi-queue support

Posted by Stefan Hajnoczi 3 years, 7 months ago

The vhost-user-blk server currently only supports 1 virtqueue. Add a
'num-queues' option for multi-queue. Both --device
vhost-user-blk-pci,num-queues= and --export vhost-user-blk,num-queues= need to
be set in order for multi-queue to work (otherwise it will fall back to 1
virtqueue).
