vCLS VM IDs are zeros after patching ESXi to 8.0.3b

Products

• VMware vSphere ESX 8.x

Issue/Introduction

vCLS VMs had names with proper UUID, and now appear with names of all zeros for the UUID of the VM.

• vCLS VMs for other clusters of hosts are not affected.

 

Example: "vCLS-00000000-0000-0000-0000-000000000000"

Environment

vSphere 8.0

Cause

Required fields in host hardware BIOS/firmware missing values (e.g., S/N, etc.).

Resolution

Third Party issue as the UUID is provided by the hardware to the hypervisor. Hardware vendor must validate in the hardware level for the proper UUID of the host.

• Upgrading the BIOS/firmware of the affected ESXi hosts has resolved the issue.
