Restart Toolstack

The Restart Toolstack option allows you to restart the Citrix Hypervisor management toolstack. This toolstack controls VM lifecycle operations, host and VM networking, VM storage, and user authentication. It allows the management of Citrix Hypervisor resource pools. The toolstack provides the publicly documented Management API, which is used by all tools that manage VMs and resource pools.


Sometimes, the Restart Toolstack option can be used for troubleshooting Citrix Hypervisor issues. However, be cautious when using this option, as incorrect usage can cause unexpected results.

To restart toolstack

  1. Select the server in the Resources pane.
  2. On the Server menu, click Restart Toolstack.
  3. Click Yes to confirm.


When you run the Restart Toolstack option on the Pool Master, XenCenter loses connection to the pool. Wait for 30 seconds after losing connection, and then reconnect manually.
