Disabling the automatic virtual machine migration
There are a few use cases, such as using Red Hat's high-availability add-on inside the Red
Hat Enterprise Linux guest operating system for the application's high availability or
Cluster Suite on the RHEV infrastructure, where we need to disable the automatic virtual
machine migration. This can be achieved by pinning the virtual machine to run only on a
specific host. Pinning the virtual machine to run only on the selected host will prevent the
automatic live migration in the case of that specific host's failure.
To pin a virtual machine to a specific host, perform the following steps.
1. Log in to the Administrator portal, and navigate to the Virtual Machine tab.
2. Select the appropriate virtual machine, right-click on it, and select Edit .
3. In the Edit Virtual Machine window, select Show Advanced Options , as shown
in the following screenshot.
4. Move to the Host tab, select Start Running On , uncheck Any host the Cluster ,
select the Specific radio button, and select the host from the drop-down menu.
5. Finally, under the Migration Options drop-down menu, select Do not allow mi-
gration , and click on OK .
