Re: [ovirt-users] Advise needed: building cheap HA oVirt cluster with just 2 physical servers

Hi, cockpit is enabled by default when you use ovirt-node. You will probably have to install the necessary cockpit packages yourself on pure CentOS - you will need cockpit and ovirt + gdeploy cockpit plugins (sadly I do not recall the exact package names). With regards to arbiter and the wizard.. I really do not know, but I will alert my colleagues who might have more detailed knowledge of the gluster part. Denis, Sahina: can you please help me here?
