and upstream apparently crashes with assert(vrng->conf.max_bytes <= (9223372036854775807L)) Feel free to fix it upstream and close this as WONTFIX for RHEL6.
Submitted upstream, but awaiting merge. http://lists.gnu.org/archive/html/qemu-devel/2014-07/msg02348.html
Accepted upstream http://git.qemu.org/?p=qemu.git;a=commit;h=713e8a102222b6b8ca65050d13b287f5705831b0 backported and posted to rhvirt-patches.
Fixing another issue upstream first before resubmitting.
