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
Install KVM real machine
This is a excellent article on how to setup the real host system: https://www.linuxtechi.com/install-kvm-hypervisor-on-centos-7-and-rhel-7/
3. Networking
We use bridge networking API. Things you need to do is:
- real host: all IPs must run on the bridge interface and not on the real network
- real host: assign the bridge device to your real network interface
- VM: assign the VM to your new bridge device
