 ## Host reboot procedure
 
+1. Disable the host so that no new VM can be started on this host and so that the rest of the pool knows that the host was disabled on purpose.
+   From command line:  
+   [shroot]
+
+   ```sh
+   xe host-disable host={hostname}
+   ```
+
+   [/shroot]
+
+2. Migrate the VMs running on the host to other hosts in the pool, or shut them down.
+
+3. Reboot or shutdown.
+   Can be done from XO, or from command line
+   [shroot]
+
+   ```sh
+   xe host-reboot|host-shutdown host={hostname}
+   ```
+
+   [/shroot]
+
+4. (After a reboot or host startup) Move VMs back to the host if appropriate. There is no need to re-enable the host: it is done automatically when it starts.
