vToolbelt – November 2019

Hello everyone!  I can’t believe it is the end of November already.  Thanksgiving is nearly upon us so I’ll keep the virtualization news light.  A few key things this month:

  • A number of core vSphere products are nearing the end of General Support (particularly vSphere 6.0 & vCenter Server 6.0).  You can find out the exact date in the Product Watch section.
  • The last Ohio SLED VMUG for 2019 is on 12/3.  We will be talking about VMware Skyline and a recap of VMworld.  Arctic Networks is sponsoring and will be presenting on the Security Operations offering. We hope to see you there!  You can register at VMUG.COM.
  • Earlier this month I sent out a message about a new Speculative Execution bug (VMSA-2019-0020).  The full remediation for this issue has 2 parts (patch the code and make a config change to enable the full fix).  The required config change is noted in the advisory but unfortunately is a bit buried.  You can find the details in KB 59139.  This is linked in the overall advisory but isn’t called out as well as it could be.  Please read the full document.  There are performance impacts – particularly for anyone running Nested Virtualization.

Upcoming Events

Date: Tuesday, December 3rd
Time: 8:30AM – 11:30AM


  • VMware Skyline – This is a free tool available to anyone with valid support contract.  It can help make the support experience better.  If you hate uploading log bundles you need to check this out!
  • VMworld 2019 recap
  • Arctic Wolf – they are sponsoring the event and will discuss their Cyber Security Operations offering

Home Lab Update – Adding a NAS

It has been a while since I have written about my home lab.   While the initial purpose was to help me learn, I have been using it more and more to allow me to assist customers.  It has been really useful when talking on the phone or researching topics for them.  So when I had to reconfigure it earlier this summer to brush up on the new release of Site Recovery Manager for booth duty at VMworld, I began to miss it quickly.

My lab is comprised of 3 white-box ESX hosts in a cluster with vSAN.  While each host has a local disk, the only shared storage I have is vSAN.  Normally this works just fine for my needs; but SRM requires 2 separate vSphere environments and in my 3 host scenario it meant that vSAN had to temporarily come down.  I’ve reconfigured the environment back to a single cluster with vSAN; but the exercise has made me wish I had some type of shared storage capability outside of my vSphere environment.  I know SAN/NAS for home labs isn’t a new topic these days; but I learned a few things along the way and I thought I would share in case there are others who are still doing this for the first time.

I had resisted the idea for a while mostly due to cost; but also because I wasn’t sure that I would fully utilize another piece of gear.  TL;DR  Now that I have have it – I love it and in the space of about 10 days have it setup and am getting far more out of it than I had anticipated.  Let’s break down what I am doing…

Adding Async VMware Tools versions to Update Manager

Why aren’t VMware Tools at the right version on patched hosts?

A customer called with a question about updating VMware Tools as part of a recent security patch (https://www.vmware.com/security/advisories/VMSA-2019-0009.html).    The patch resolves an address out-of-bounds vulnerability in VMware Tools that was present in certain versions of the software (10.2.x and 10.3.x prior to 10.3.10).  He wanted to install the new version; but the VMware Tools installations on his VMs indicated they were current; but still were running an affected version.  His hosts were patched and up-to-date.  He knew he could manually update VMware Tools on each of his VMs; but was hoping there was an easier way – and there is!

The status of VMware Tools on a virtual machine is relative to the the host.  Typically VMware Tools updates are delivered through an ESXi patch.  In this case, the VMware Tools 10.3.10 release hasn’t been rolled into an ESXi patch yet.  It will be shortly.  The amount of testing that goes into an ESXi patch requires a good amount of time.  When VMware patches VMware Tools like they did in the case of this vulnerability, they release it to customers so they can deploy the fix sooner if they choose.  VMware calls this an Async release.
