There's F21 qemu-2.0 builds here:
http://koji.fedoraproject.org/koji/buildinfo?buildID=538383
And 1.7 builds here: http://koji.fedoraproject.org/koji/buildinfo?buildID=499026

There might be dependency issues trying to install on latest f21, if they were
built against older libraries. Worth a shot though. Besides that something
custom will need to be built, though at that point it's probably easier to
build qemu from source
