You probably want to use qemu-kvm-rhev instead of qemu-kvm.  Quoting
Paolo Bonzini's earlier mail
(https://lists.gnu.org/archive/html/qemu-devel/2014-11/msg03379.html):

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

http://resources.ovirt.org/pub/ovirt-3.5/rpm/el7Server/

This yum repository file will help:

    [qemu-kvm-rhev]
    name=oVirt rebuilds of qemu-kvm-rhev
    baseurl=http://resources.ovirt.org/pub/ovirt-3.5/rpm/el7Server/

mirrorlist=http://resources.ovirt.org/pub/yum-repo/mirrorlist-ovirt-3.5-el7Server
    enabled=1
    skip_if_unavailable=1
    gpgcheck=0

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
