Subject: [Qemu-devel]  question about vioscsi queue depth patch
Date: Tue, 9 Dec 2014 16:20:49 +0800	[thread overview]

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
