When a vSphere ESXi host restarts after a power failure, the virtual machines that are deployed on the host do not start automatically. You must configure the virtual machines to start automatically.
In high availability (HA) clusters, the VMware HA software does not use the startup selections.
Before you begin
Verify with the ESXi system administrator that you have the permissions to configure the automatic startup settings.
Procedure
In the web browser, type the vSphere vCenter host URL.
Click one of the following icons: Hosts and Clusters or VMs and Templates icon.
In the navigation pane, click the host where the virtual machine is located.
Click Manage.
In Virtual Machines, click VM Startup/Shutdown, and then click Edit.
The software displays the Edit VM Startup and Shutdown window.
Click Automatically start and stop the virtual machines with the system.
