Features of RHEV

With RHEV, you can virtualize even the most demanding application workloads with features including the following:

  • Host scalability: This supports a limit of up to 160 logical CPUs and 2 TB per host (platform capable of up to 4,096 logical CPUs / 64 TB per host)
  • Guest scalability: This supports up to 160 vCPU and 2 TB VRAM per guest
  • KSM memory over commitment: This allows administrators to define more RAM in their VMs than what is present in a physical host
  • Security: This supports SELinux and new sVirt capabilities, including Mandatory Access Control (MAC) for enhanced virtual machine and hypervisor security
  • Management: This provides centralized enterprise-grade virtualization management engines with a graphical administration console and programming interfaces
  • Live migration: This allows running virtual machines to be moved seamlessly from one host to another
  • High availability: This allows critical VMs to be restarted on another host in the event of hardware failure with three levels of priority
  • System scheduler: This provides system scheduler policies for load balancing to automatically balance the VM load among hosts in a cluster
  • Power saver: The power saver mode is used to consolidate VM loads onto fewer hosts during nonpeak hours
  • Maintenance manager: This allows you to move the hypervisor into the maintenance mode for any software or hardware updates of the hypervisor
  • Image management: This supports template-based provisioning, live virtual machine snapshots, and cloning new virtual machines from snapshots
  • Monitoring and reporting: This provides a suite of preconfigured reports and dashboards and creates your own ad hoc reports that enable you to monitor the system
  • OVF import/export: This allows you to import and export Open Virtualization Format (OVF) virtual machines into RHEV
  • V2V: This automates the conversion of the VMware or Xen virtual machine images into an OVF file for use within RHEV
