...k is in-kernel accelerator for virtio-blk. At this time, this is a prototype based on virtio-net. Lots of error handling and clean up needs to be done. Read performance is pretty good over QEMU virtio-blk, but write performance is not anywhere close to QEMU virtio-blk. Why ?

Hi All, Here is the latest version of vhost-blk implementation. Major difference from my previous implementation is that, I now merge all contiguous requests (both read and write), before submitting them. This significantly improved IO performance. I am still collecting performance numbers, I will be posting in next few days. Comments ? Todo: - Address hch's comments on annontations -
