Hello all.

I just installed ovirt node and the hosted engine on a single host. As the 
setup did not offer a option for local filesystems, I used a iscsi LUN on the 
same host. So the engine got installed there. That LUN is a on a nvme disk, the 
kind that reads higher than 3GB/s. Yet,  on a vm, i cannot get more than 
280MB/s. That's using virtio-scsi or virtio as the interface. Using SATA gives 
around 350MB/s. I tested with dd, like:
Bechmarking writes: dd if=/dev/zero of=/root/test bs=1M count=7000 
status=progress
Bechmarking reads: dd if=/root/test of=/dev/null bs=1M  status=progress

Also with hdparm -t /dev/sda

Is ISCSI supposed to be this slow? Again, this is on the same machine.
