Virtual Machine summary page on vSphere Client may not display IP Addresses for Ubuntu Kubernetes machine

Products

• VMware vSphere ESXi

Issue/Introduction

• Ubuntu virtual machines (VMs) running Kubernetes may not display IP addresses on the Summary page.
• Issue is observed under the following conditions:
  
  
  • open-vm-tools version installed is older than 12.3.x.
  • Listing of IP addresses/Interfaces in the Guest OS results in 15 or more entries
     vmtoolsd --cmd "info-get guestinfo.ip
    
    
• The Guest OS reports the primary IP address from the following command
   ip address

Cause

Earlier versions (prior to 12.3.x) of open-vm-tools lack advanced filtering for container-related network interfaces.
Native filtering for container interfaces such as Calico (cali*) was introduced in open-vm-tools version 12.3.x. and newer.

Resolution

In order to resolve the issue, proceed to upgrade the Guest OS to a version supported for open-vm-tools 12.3.x or later.
As a workaround, configure VMware Tools to ignore specific network interfaces by adding the exclude-nics: Configuring VMware Tools to Exclude Network Interfaces
