I'm not applying this for now. It seems too easy to create illegal configurations with it, e.g. where max seg > queue size. 1022 also seems too aggressive - e.g. if a couple of segments cross page boundaries, we'll exceed the iov length. around 500 seems more prudent. Guerd, could you pls also take a look at whether seabios is smart enough to downgrade if guest queue size is too big? > Signed-off-by: Denis V. Lunev <d...@openvz.org> > CC: "Michael S.
