Open Stack

It would be really cool if there were openstack examples for each container/image format.

I don't currently understand how the container format connects into the actual image (and the result with nova-compute).
Since it seems like say when u upload an iso, ovf doesn't make sense (so would that be the bare type?)
Or if u do the following "disk_format=vhd container_format=ovf type=raw" < windows.ova why is it needed to specify the disk_format? Isn't that part of the ova structure?

Also, will these varying types of formats work with VM's used by openstack.
Is there a conversion that occurs when a VM is started to the right format (for say kvm? or for say xen? since I doubt either takes the ova format directly...).

Just an FYI, Glance does not (currently) do any inspection to ensure
that what the user is registering in Glance is in fact the disk or
container format that the user says it is.

XenServer supports OVF images, and I believe Rackspace teams have
tested with OVAs. You can see some basic discussion here:
