I finally found time to switch from virtio-scsi to virtio. Seems to have make
a big difference.
The windows VMs boot faster, web pages load faster, same with the Fedora 20
VMs.
Everything just feels smoother.
I found this interesting presentation:

No, but I have been meaning to, out of curiosity.
But why do you say virto-blk will be faster than virtio-scsi? The

Hi,
I suspect most users didn't complain because
they do not have high IO workloads (yet).
I think most people run test setups (as do I).
However,
in my own (artificial) IO workload test
on engine 3.2.3. there was no extreme cpu penalty
