This repository hosts an implementation of a provider for Libvirt for the cluster-api project.
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
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
