What could be the source of error?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
