Hi,


i noticed a while ago that if I start a job like this in a vserver:


dd if=/dev/zero of=/x bs=1M count=128 oflag=direct


I see each of the 1M request splitted into 516096 + 516096 + 16384 bytes with 
virtio-scsi


If I use virtio-blk the request goes through with 1M size.


Any idea whats the cause of this?


Thanks,

Peter
