Actually, they are available in most distributions except RHEL and
CentOS. For various reasons that I cannot really detail here, Red Hat
is only shipping these features as part of the "Red Hat Cloud
Infrastructure" product.
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 yet.
Thanks,
Paolo
