Almost all Spice features being developed upstream are coming from RHEL/RHEV RFE-s, backporting all the necessary changes from upstream to the RHEL-6 packages, will result in backporting aprox. 90% of all changes, leading to almost identical yet subtle different source trees (with subtle different behavior and/or bugs) for RHEL-6 and upstream/Fedora/what will be in RHEL. Therefor we would like to rebase the spice packages to the latest upstream. These changes are needed for support for seamless migration and USB live migration.
This is fixed by usbredir-0.5.1-1.el6, moving to modified.
