Hi, while developing/testing the vdpa-blk support in libblkio [1], I realized that we added several regressions with the "[PATCH v2 00/19] Control VQ support in vDPA" series (patches/clarifications already sent). To minimize these problems in the future, I was thinking of adding tests for vhost_vdpa in tools/virtio using vDPA simulators as devices. What do you think about this? Before starting, please let me know if we already have something. Thanks, Stefano [1] https://gitlab.com/libblkio/libblkio
