The KVM Roll installs and configures Virtual Machines (VMs) on Rocks Clusters.
A physical frontend can configure VMs on client nodes (VM container appliances). A VM container is a physical machine that houses and runs VMs.
The KVM Roll also supports building virtual clusters. The frontend can be installed as a VM server appliance and the client nodes can be installed as VM containers. Then a virtual frontend can be installed on the VM server while virtual compute nodes can be installed on the VM containers. All network traffic is encapsulated within a unique VLAN, that is, each virtual cluster has its own VLAN.
Please visit the KVM site to learn more about their release and the individual software components.
