Just a friendly bump. To clarify, the ideas being tossed around are to host
QCOW images on each Compute node so the provisioning is faster (i.e. less
dependency on network connectivity to a shared back-end). I need to know if
this is possible or not. So far, I've seen nothing that suggests that it is
but i want to confirm that.

Also, derived images is a QCOW thing[1], I'm wondering if creating these
dynamically is supported by Nova and/or Glance.
