RHEV Manager, also called the RHEV-M management console, provides a Web Interface for managing virtual machines (VMs) running on physical nodes. The nodes themselves can be configured with the RHEV-H hypervisor or as Red Hat Enterprise Linux (RHEL) servers with a virtualization entitlement. In an effort by Red Hat to be 100% open source, RHEV management is browser-based and can be accessed from any platform. RHEV does not mandate any specific storage requirements, but it contains a central storage repository. The underlying kernel-based virtual machine (KVM) hypervisor is integrated into the Linux kernel, which allows for cost savings as well as security and performance improvements over other platforms.
