Suspend and Resume a VM

September 26, 2024

Contributed by:

When you suspend a VM, its current state is stored in a file on the default storage repository (SR). This feature allows you to shut down the VM’s host server. After rebooting the server, you can resume the VM and return it to its original running state.

Note:

It might not be possible to resume a suspended VM that was created on a different type of server. For example, a VM created on a server with an Intel VT-enabled CPU might not be resumed on a server with an AMD-V CPU.

To suspend a VM

If the current default SR is detached, select a new default SR.
Select the VM in the Resources pane and then select Suspend on the Toolbar.

Alternatively:
- Right-click and select Suspend on the shortcut menu.
- On the VM menu, select Suspend.
When a VM has been suspended, its status indicator changes to the Suspended VM icon in the Resources pane.

To resume a suspended VM

For VMs in a pool, you can normally choose where to resume them. Your choice of server depends on how the VM and the pool are configured:

In a pool with Workload Balancing (WLB) enabled, recommendations are provided to help you choose the best possible physical server for the VM’s workload.
In a pool without Workload Balancing configured, you can resume the VM on any server in the pool (subject to available storage on that server). For more information, see Home server.

When a suspended VM has been successfully resumed, its status indicator changes to the VM Running icon in the Resources pane.

VM Running icon - a VM icon with a green play icon overlaid.

To resume a suspended VM on a specific server

Select the VM in the Resources pane.
Right-click and select Resume on Server and then select the server you want on the shortcut menu. Alternatively, on the VM menu, select Resume on Server and then select the server you want on the submenu.

To resume the VM automatically on the optimal or home server

Select the VM in the Resources pane and then select Resume on the toolbar.

The Resume icon - a blue circle with a white play icon overlaid.

Alternatively, do one of the following:

Right-click in the Resources pane and select Resume on the shortcut menu.
On the VM menu, select Resume.

In a WLB-enabled pool, the VM starts on the optimal server.

In a pool without Workload Balancing configured, the VM starts on its home server. If no home server has been set or if the nominated server is unavailable, the VM starts on the first available server.
