4.2. Power Management by Proxy in Red Hat Virtualization
4.2. Power Management by Proxy in Red Hat Virtualization The Red Hat Virtualization Manager does not communicate directly with fence agents. Instead, the Manager uses a proxy to send power management commands to a host power management device. The Manager uses VDSM to execute power management device actions, so another host in the environment is used as a fencing proxy. You can select between: Any host in the same cluster as the host requiring fencing. Any host in the same data center as the host requiring fencing. A viable fencing proxy host has a status of either UP or Maintenance .
