Hi Anthony,
I started a guest with cache=none and aio=threads
When i did some io tests in Guest say dd like
dd if=/dev/zero oflag=direct of=/mnt/sdb1/date.img bs=4k count=262114
qemu will start one or several threads to perform IO requests.
It seems qemu makes use of its own posixaio. I'm wonde

When i did some io tests in Guest say dd like
dd if=/dev/zero oflag=direct of=/mnt/sdb1/date.img bs=4k count=262114
qemu will start one or several threads to perform IO requests.
It seems qemu makes use of its own posixaio. I'm wonde
