Hi Vadim, I test the vioscsi 0001-queue-depth254.patch for virtio-win-0.1-74 with minor modifications about
virtio api, because it have not updated to use the linux api. When a VM with four disks in one controller and 4kb 32depth sequential read for each disk at the same time, the tool of iometer which simulates the IO model become no response. If fit the patch into virtio-win-0.1-94, it works well. Is there some bug with the old virtio api, or is there some reason that the patch can not work normally in virtio-win-0.1-74? Best wishes, Ting Wang
