Hi, This patch series add support for virtio-blk num-queues. It's was already implemented for virtio-scsi.
It's also enable numqueue to maxcpus for qemu 8.0. Redhat already was enabled by default in rhev in 2011, so it's pretty stable. https://bugzilla.redhat.com/show_bug.cgi?id=1827722 It's improve performance for fast storage like nvme,optane by around 20%. My fio bench have jump from 200k to 240k iops with 4 block I don't have seen perf regression (running them for 1month), but user is still able to override queues and set it to 1.
