We also use CentOS 7 on the real machines. This makes life easier, because we only need to know CentOS config style. Of cause you could use other Linux distribution on the real host.

1. Step:

Install CentOS 7

2. Step:

Install KVM

Required packages:

cat << EOF > /etc/yum.repos.d/qemu-kvm-rhev.repo
[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
EOF

yum install qemu-kvm-rhev libvirt bridge-utils
# qemu-img is not needed

Start libvirt:

systemctl start libvirtd
systemctl enable libvirtd

3. Networking

We use bridge networking API. Things you need to do is:

1. real host: all IPs must run on the bridge interface and not on the real network
2. real host: assign the bridge device to your real network interface
3. VM: assign the VM to your new bridge device
