OpenShift cluster-api-provider-libvirt

This repository hosts an implementation of a provider for libvirt for the OpenShift machine-api.

This provider runs as a machine-controller deployed by the machine-api-operator

Allowing the actuator to connect to the libvirt daemon running on the host machine:

Edit /etc/libvirt/libvirtd.conf to set:

listen_tls = 0
listen_tcp = 1
auth_tcp="none"
tcp_port = "16509"

Edit /etc/systemd/system/libvirt-bin.service to set:

/usr/sbin/libvirtd -l

Then:

systemctl restart libvirtd

Allow incoming connections:

iptables -I INPUT -p tcp --dport 16509 -j ACCEPT -m comment --comment "Allow insecure libvirt clients"

Verify you can connect through your host private ip:

virsh -c qemu+tcp://host_private_ip/system

Run it with the installer

Before running the installer make sure you set libvirt to use the host private ip uri above: https://github.com/openshift/installer/blob/master/examples/tectonic.libvirt.yaml#L14
