I can confirm that increasing BLOCKIF_IOV_MAX from 33 to 128, like the diff shows, solved the problem for me. I've successfully done some performace tests on Windows7 (virtio-blk vs. ahci,hd:) and also migrated one Server 2012R2 to bhyve using virtio-blk. Peter, is your mentioned fix different from just increasing BLOCKIF_IOV_MAX? If not, would you commit that please?
