Yes, It will be usefull for testing the guest code. Currently virtio-blk
does not returns the multi-queue in feature flag of virtio, so no way
testing the feature in the guest driver.
In the virtio-net, multi-queue feature can be enabled and tested.
Thanks

HI,
I am trying to improve the throughput of virtio-blk for my kernel (
https://github.com/naredula-jana/Jiny-Kernel ) to make use of the
multi-core using multi-queue. But I found the latest qemu does not support
multiqueue for virtio-blk, The feature flag does not return multi-queue
