Issue/Introduction

• A new Tanzu Guest Cluster was created, but is not deployed. The new deployed virtual machine might show some hardware configuration, but is never powered on.
• When checking vCenter tasks of respective namespace, the vCenter task "Deploy OVF template" is not moving beyond 0% progress.
• After couple of minutes, above task "Deploy OVF package from Content Library to Resource Pool" eventually shows "Copying virtual machine configuration", but not progresses
• In respective logs of Content Library at /var/log/vmware/content-library/cls.log, it can be observed value "bytes_transferred" not increasing over an extended period of time:
  (In this example, referring to VMDK "ubuntu-ova-disk1.vmdk" of a Tanzu Kubernetes Release from Broadcom-hosted Tanzu-specific Content Library)
