Qlusters vice president of marketing John Harleman said openQRM takes the benefits of virtualization and enables users to apply them to, and between, physical and virtual systems.

"With openQRM users can use the virtualization technology of their choice where it makes sense and physical systems where it does not," Harleman said, adding customers often reap manifold increases in efficiencies as well as an ability to view and manage their physical and virtual systems.

Freely available under a modified Mozilla Public Licence since 2004, openQRM includes an agent to monitor CPU utilization and system health as well as communicate with the openQRM server.

"OpenQRM can also integrate with the monitoring technology of your choice, for instance [the open source] Nagios, and leverage the monitoring metrics to provide HA or load management," Harleman said.

Qlusters developed openQRM with a modular, plug-in framework which has led to support for virtual machines.
