OK, I played around a bit with Stefan's block branch rebased upon current master (and the conflict fixed up)... and I can't seem to hit any error with virtio-ccw (will see if I find time to play around with virtio-pci; but unless I've messed up, this should be the same code path). VIRTIO_BLK_F_MQ is correctly negotiated if num_queues > 1, and I can use the disk. So, two questions: - Which branch are you using? Any chance of a mis-merge there? - Can you share the interesting portion of your command line?
