VMware Knowledge Base article 78708 provides critical instructions for installing VMware Tools on older Windows operating systems, specifically Windows 7 SP1 and Windows Server 2008 R2 SP1. Summary of KB 78708
The article addresses a common installation failure where the VMware Tools installer (version 11.1.x and newer) requires the guest OS to support SHA-2 code signing. Without specific Microsoft updates, the installer cannot verify driver signatures and will fail. Required Steps to Fix
To resolve this issue and successfully install VMware Tools for free, you must manually download and install two specific Microsoft security updates on your virtual machine: KB4474419: SHA-2 code signing support update. KB4490628: Servicing stack update (SSU). Standard Procedure:
Download these updates using a web browser within the guest OS (note that older versions of Internet Explorer may fail; using an alternative like Chrome is recommended). Install both updates and restart the virtual machine.
Mount the VMware Tools installer again and proceed with the installation as normal.

VMware Knowledge Base article 78708 states that Windows 7 SP1 and Windows Server 2008 R2 SP1 guests require the Microsoft SHA-2 security update (KB4474419) to install VMware Tools 11.x and later, as shown in studies and community discussions. A potential feature to address this is an automated pre-check that scans for this specific KB, identifies the guest OS, and prompts the user to install the update if missing.

Understanding VMware KB 78708: How to Free Up Space on Your VMware Appliances
VMware Knowledge Base article 78708 is a critical resource for system administrators managing VMware vCenter Server Appliances (VCSA). It provides a specific script and set of procedures designed to identify and remove unnecessary files that often bloat the appliance’s storage partitions. When these partitions reach 100% capacity, the vCenter services frequently fail to start, leading to management downtime. Why Your VMware Appliance Runs Out of Space
The vCenter Server Appliance is a Linux-based virtual machine with several dedicated partitions. Over time, these areas can fill up due to:
Audit and Syslog Data: Historical logs that haven't been rotated properly.
Old Patch Files: Leftover data from previous VCSA updates or installations.
Crash Dumps: Large core dump files created during service failures.
Temporary Files: System cache and temporary data that wasn't automatically cleared. kbvmware s article 78708 free
When the /storage/log or /storage/seat partitions hit their limit, the Postgres database or the vpxd service may crash, preventing you from logging into the vSphere Client. How to Use the KB 78708 Cleanup Script
The primary solution offered in KB 78708 is the execution of a automated cleanup script. This is much safer than manually deleting files via the command line.
Backup Your Appliance: Before running any cleanup script, take a snapshot of your vCenter Server Appliance.
Access the Shell: Log in to the VCSA via SSH or the VM console using root credentials. Type shell to enter the BASH interface.
Download/Locate the Script: The KB article provides a script (often named cleanup_vcsa.py or similar in later iterations). If your environment is offline, you may need to copy the script content manually into a new file on the appliance.
Execute the Script: Run the script with Python. It will scan the common directories for "safe to delete" files, such as old logs and temporary update files.
Restart Services: Once the space is reclaimed, you may need to restart the VCSA services using the command: service-control --start --all. Manual Cleanup Areas to Monitor
If the script does not resolve all issues, KB 78708 and related documentation point to several specific directories that often require manual intervention:
/storage/core: Look for large core.* files. These are memory dumps from crashed processes. If you don't need them for a support case, they can be deleted.
/storage/log/vmware/sso: Check for old localhost_access_log files that may have accumulated over months.
/storage/updatemgr: If you use Update Manager or Lifecycle Manager, old patches and metadata can consume significant space here. Preventing Future Disk Space Issues
To avoid recurring "disk space full" errors, consider the following maintenance steps:
Configure Log Rotation: Ensure your syslog settings are not set to "verbose" unless you are actively troubleshooting.
Monitor Disk Usage: Set up alarms in vCenter to notify you when partition usage exceeds 80%.
Regular Patching: VMware often releases updates that improve log management and automatic cleanup routines.
Increase Disk Size: If your environment has grown significantly, you can use the vSphere Client to increase the size of the virtual disks (VMDKs) attached to the appliance, then use the vpxd-service-control tools to expand the logical partitions. Image: A screenshot of the vSphere Client "Snapshot
By following the guidance in KB 78708, administrators can quickly restore functionality to their vSphere environment without needing to redeploy the entire management server. Always ensure you are viewing the most recent version of the article on the official VMware (Broadcom) Support portal for the latest script updates.

Title: Just a heads up on KB 78708 (VCSA Backup Issues)
Hey everyone,
Just wanted to share a quick win. I was running into issues with a VCSA backup failing intermittently. The logs were vague, pointing generally toward "snapshot creation failure."
After a bit of digging, I found VMware KB 78708 (free access, no login required for basic viewing).
The article breaks down the exact registry/config checks needed to clear out the stale snapshot references that were blocking the backup. If you are seeing errors like "Operation timed out" or "Snapshot creation failed" in your backup logs, give this KB a read. It’s much faster than opening a support ticket.
Hope this saves someone else a headache!
Headline: Is your VCSA backup failing? KB 78708 might be the fix you need. 🛑
If you've been staring at a failed backup job for your vCenter Server Appliance (VCSA), you aren't alone. One of the most frustrating errors occurs when the backup mechanism fails due to snapshot limitations or stale snapshot references.
I stumbled across VMware KB 78708 recently while troubleshooting a persistent backup failure, and it’s a goldmine for a specific edge case that often gets overlooked.
The Takeaway: Often, the issue isn't with the backup software itself, but how vCenter handles the snapshot creation process during the backup window. The KB details how to check for stale snapshots and, crucially, how to manually intervene without breaking your backup chain.
Why this matters: Backup verification is the unsung hero of IT. If your VCSA backup is failing silently, you are one power outage away from a very bad day.
