qemu 2.1 is not released yet, but yes, rawhide (and therefore the
fedora-virt-preview repo on Fedora 20) are currently shipping qemu
2.1-rc0 (and soon rc1). Note that 2.1-rc0 has a bug that prevents
libvirt from using qemu properly, which upstream qemu hopes to have
fixed in time for the actual 2.1 release.

Because CentOS borrows from RHEL, and the engineers at Red Hat have
determined that enterprise stability is worth backporting thousands of
carefully vetted patches rather than rebasing potentially unstable code
that picks up even more unaudited upstream commits.

If you need newer code but still with assurances of enterprise quality
performed by Red Hat, then consider using RHEL 7.0 (and CentOS 7 can't
be too far behind...)
