Issue/Introduction

When attempting to transition a VMware Cloud Foundation (VCF) cluster from vSphere Lifecycle Manager (vLCM) baselines to vLCM images, the transition fails during the image seeding phase.

The vCenter Server displays the following error during the "Extract image" task: A general system error occurred:

Cannot download offline depot from 'https://<REDACTED_HOSTNAME>/cgi-bin/host-seed.cgi?path=/var/vmware/lifecycle/hostSeed/OfflineBundle-<REDACTED>.zip'. Create and import of offline depot from host <REDACTED_HOSTNAME> failed.

The SDDC Manager displays the following error during the "Determine the image to be applied to the cluster" task:

SDDC Manager error code: "DRAFT_CREATION_FAILED"

Environment

VMware Cloud Foundation 5.2.2
vCenter Server 8x

Cause

  • The vCenter Server Appliance proxy configuration (/etc/sysconfig/proxy) contains invalid syntax in the NO_PROXY bypass list, specifically the use of regular expressions wildcards or CIDR blocks.
  • The Java-based vLCM service cannot parse this syntax, causing internal ESXi host requests to be erroneously routed to the external proxy server where they are dropped.

Resolution

  1. Establish an SSH session to the vCenter Server Appliance (vCSA) as root.

  2. Open the /etc/sysconfig/proxy file using a text editor.

  3. Modify the NO_PROXY list to remove any regular expressions (e.g., .*.<REDACTED_HOSTNAME>) or CIDR network notations (e.g., <REDACTED_IP>/24).

  4. Replace the removed entries with standard domain suffixes (e.g., .<REDACTED_HOSTNAME>) and explicit IP addresses.

  5. Save and close the /etc/sysconfig/proxy file.

  6. Restart the proxy network service by executing: /etc/init.d/proxy restart

  7. Restart the vLCM Update Manager service by executing: vmon-cli -r updatemgr

  8. Re-execute the vLCM baseline to image cluster transition workflow.
