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.
