Hi *,

Today we did some performance testing in the default install vms. And we got very poor harddisk performance in the virtualization layer.

on the server approx 450 MB/s insode the VM around 30 MB/s 

how are your virtual instances on disk writes? is there any known openstack/kvm setting/issue which could cause that poor performance?
