Open Stack

What does ³Flavor sizes² include? Memory, CPU count? Is there a
wide-enough care for other measures of performance or compatibility like:
- virtualization type: none (hardware/metal), xen, kvm, hyperv
- cpu speed, cache or some form of performance index
- volume types: SATA, SSD, iSCSI, and a performance index
