Virtualization

High-Availability oVirt-Cluster with iSCSI-Storage

oVirt is a management application for virtual machines that uses the libvirt interface. It consists of a web-based userinterface (oVirt Manager), one or more hypervisors, and data storage for the virtual guests.

This techguide describes how to deploy a high available oVirt Cluster with an DBRD backed iSCSI Storage. The document handles the configuration of DRBD, Pacemaker, Heartbeat and oVirt configuration.
