Hi Massimo, You can upload the images twice, in both qcow2 and raw format, then create a host aggregate for your "local-disk" compute nodes and set its metadata to match the property you'll set on your qcow2 images. When somebody will start a qcow2 version of the image, it will be scheduled on yo

I totally agree with Jay, this is the best, cheapest and most scalable way to build a cloud environment with Openstack. We use local storage as the primary root disk source which lets us make good use of the slots available in each compute node (6), and coupled with the Raid10 gives good I/O pe

ging on the console. You could create a special role that has console access and change the policy file to reference that role for the "compute:get_vnc_console", for example. I don't think you can do it on per-flavor basis. Cheers, George On Thu, Oct 27, 2016 at 10:24 AM, Blair Bethwaite
