Sure, but that's not the issue.  The issue is VM portability.  It's important, but difficult.  That's my point.  Specifying the hypervisor of an image just means the cloud has enough foreknowledge to reject the upload.

If you don't have this capability then allowing the upload of completely opaque images and hoping they will have any kind of reasonable performance on an arbitrary cloud providers system is a pipe dream.  This is an area badly in need of standardization, but I doubt it will come any time soon.

Fortunately specifying the type of hypervisor an image is tied to/optimised for isn't hard...
