What could be the source of error?You probably want to use qemu-kvm-rhev instead of qemu-kvm.  QuotingPaolo 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 aboutofficial 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=0Drop it in /etc/yum.repos.d/qemu-kvm-rhev.repo and install qemu-kvm-rhevwith yum.  All features will be available.  It would be simpler to havea CentOS SIG build this, but it hasn't happened
