RHEV Architecture

Red Hat Enterprise Virtualization Management (RHEV-M) is a virtual management console built on Red Hat Enterprise Linux (RHEL). It interacts with individual RHEV-Hosts using the Virtual Desktop Server Manager (VDSM). A VDSM agent is running on each of the RHEV-H nodes. RHEV-M allows administrators to manage/control number of data centers and their network, compute and storage resources. In addition RHEV-M provides a central repository for storing virtual machines, disks, images and virtual machine snapshots.

Install RHEV-M Hardware Requirements

  • Hard Disk Space Minimum 50GB
  • RAM Minimum 4GB – Max 2TB
  • Dual Core or High Processor
  • 1Gbps NIC Card

Software Requirements

  • Operating System RHEL 7
