Cause

This issue occurs due to the duplicate entry for a virtual machine in the /etc/vmware/hostd/vmInventory.xml file.

Resolution

To resolve this issue, remove the duplicate entry for the virtual machine causing this issue.

To remove the duplicate entry for the virtual machine:

1. Connect to the host using SSH. For more information, see Using Tech Support Mode in ESXi 4.1, ESXi 5.x, and ESXi 6.x.
2. Navigate to the /etc/vmware/hostd directory using this command:
   
   cd /etc/vmware/hostd
    
3. Open the vmInventory.xml file using a Text Editor.
4. Identify the duplicate entries for the virtual machine in the vmInventory.xml file.
5. Create a backup of the vmInventory.xml file.
6. Comment or remove all the duplicate entries for the VM.
7. Restart hostd by running this command:
   
   /etc/init.d/hostd start
