You need qemu-kvm-rhev, not plain qemu-kvm.

Quoting Paolo Bonzini's earlier mail

Luckily, since you are using CentOS you do not really care about
official Red Hat RPMs, and you can get the packages here:


This yum repository file will help:

    name=oVirt rebuilds of qemu-kvm-rhev


Drop it in /etc/yum.repos.d/qemu-kvm-rhev.repo and install qemu-kvm-rhev
with yum.  All features will be available.  It would be simpler to have
a CentOS SIG build this, but it hasn't happened yet.
