  • Important Update - On Mar 20 2018, VMware VMSA-2018-0004.3 announced that CVE-2017-5715 (Spectre-2) mitigation is now included in the latest patch that you should be using instead of the older patch featured in the original article below. You'll find the newer article here:

    Article below as it originally appeared.

    Meltdown and Spectre loom large this year, and this article outlines how simple Meltdown/Spectre-1 mitigation is. But first, you should do your homework.



    1) Read VMSA-2018-0007.1

    2) Read the Release Notes

    You'll also want to carefully read the VMware vCenter Server 6.5 Update 1e Release Notes, since there currently seems to be no 1f release notes page. It contains all sorts of details you'll want to be aware of before upgrading, especially if you're running a production environment.

    Easy button advantages

    For those of you with VCSA 6.5.x already installed, the simple VAMI update method also means you won't need to bother logging in to the "My VMware" portal to download the VMware-VCSA-all-6.5.0-7119157.iso from the Download Page for:
    VMware-VCSA-all-6.5.0-7119157.iso | Release Date: 2017-11-14 | Build Number: 7119157

    This upgrade is also known as version or 6.5U1f or Build 7801515, as seen in the vCenter Server Appliance Management Interface (VAMI), as pictured above this article. I have a screenshot and video of the process below.

    Step-by-step VCSA Upgrade Instructions using the Appliance Management User Interface

    1. Create a snapshot of your VCSA appliance first, or at least do a backup using whatever VM backup software you prefer, or even the backup abilities of the VCSA appliance itself.
    2. Log in to your VCSA using VCSA VAMI (vCenter Server Appliance Management Interface) (aka Appliance Management User Interface) using the steps seen in the clear screenshot below.
    3. Click on Summary, then choose Reboot, click Yes.
    4. Test that vSphere Client is functioning properly, to know whether VCSA is working. It might be best to also verify that vSphere Web Client is also fully operational.
    5. In vSphere Client, select the VCSA appliance and right-click on it, then choose Snapshots, Manage Snapshots, DELETE ALL, then click on DONE.


    Upgrade to Build 5973321 is shown, but it's the exact same steps for Build 7801515.
