OpenNebula also supports qcow [1] but does not enforce you to use that format. We prefer to have as default the features that are common to the drivers that come packed with the distribution. It could happen that a xen installation is not prepared for qcow and people trying the software could get more problems than benefits.
There is a howto from C12G Labs that explains how to deal with qcow images.
