Warning about "RemoteDisplay.maxConnections" value when vCLS VMs powered on

Products

• VMware vCenter Server

Issue/Introduction

When vCLS VMs are powered on, following warning event is observed.

Value "true" for variable "RemoteDisplay.maxConnections" is not a valid integer value. Using value "40".

 

Environment

VMware vCenter Server 8.0U3

Cause

In vCenter Server 8.0 Update 3, there is a configuration issue where the RemoteDisplay.maxConnections parameter is incorrectly set to the string value "true" instead of an integer during vCLS deployment.
Due to this issue, the system detects that the parameter is invalid upon vCLS startup and change to the default value of 40.

Note : The RemoteDisplay.maxConnections parameter defines the maximum number of concurrent console connections allowed for the virtual machine.

Resolution

This issue is fixed in vCenter Server 8.0 U3h.

The warning has no impact on vCLS functionality and can be ignored.

 

Workaround

To suppress this warning in affected versions, modify the OVF file used for vCLS deployment on the vCenter Server and then redeploy the vCLS VMs.

Edit the file /storage/lifecycle/vmware-hdcs/photon-ova-########.ovf and modify the entry as follows:
(The value of ######## in the filename depends on the vCenter Server version.)

Original : 
<vmw:ExtraConfig vmw:key="RemoteDisplay.maxConnections" vmw:value="true" vmw:required="false"/>

Modified :
<vmw:ExtraConfig vmw:key="RemoteDisplay.maxConnections" vmw:value="1" vmw:required="false"/>

 

Note : The recommended value for RemoteDisplay.maxConnections on vCLS is "1", which is the default setting in the fixed version.

Additional Information

vCLS VMs can be redeployed by enabling and disabling Retreat Mode.
