vSphere Integrated Containers Engine Plug-In Does Not Appear in the vSphere Web Client

After you have installed the vSphere Web Client plug-in for vSphere Integrated Containers Engine, the plug-in does not appear in the vSphere Web Client.

Problem

The UI plug-in installer reported success, but the virtual container host (VCH) portlet does not appear in the Summary tab for the VCH endpoint VM. Logging out of the vSphere Web Client and logging back in again does not resolve the issue.

Cause

If a previous attempt at installing the vSphere Integrated Containers Engine plug-in failed, the failed installation state is retained in the vSphere Web Client cache.

Solution

Restart the vSphere Web Client service.

vCenter Server on Windows

Open Server Manager on the Windows system on which vCenter Server is running.
Select Configuration > Services.
Select VMware vSphere Web Client and click Restart.

vCenter Server Appliance

Use SSH to log in to the vCenter Server Appliance as root.
Stop the vSphere Web Client service by running one of the following commands.
- vCenter Server 6.0:
```
service vsphere-client stop
```
- vCenter Server 6.5:
```

```
Restart the vSphere Web Client service by running one of the following commands.
- vCenter Server 6.0:
```

```
