A very common task I run into is checking and verifying what version a build number of vCenter, ESXi and Tools (and Horizon on occasion) are installed in an environment, including my own lab, so I wanted to put a few helpful links out there. Below are links to VMware KB’s that list out the…

Latency sensitivity of a virtual machine can be changed to optimize the scheduling delay for latency sensitive applications and workloads. This feature was rolled out with vSphere 5.5, and the feature is still available as of right now in vSphere 7U3o and vSphere 8.x. As a sysadmin and/or user of vSphere… what does this really…

Using host profiles with ESXi hosts with version 7 So…why would I want to use host profiles?

Here’s a good one for y’all…I’m going to walk thought how to update the location for VMware Tools (a.k.a. the Product Locker) and change/update it, without rebooting your ESXi host. You may ask, “why would you want to do that??” Well, the main use case would be to centralize the repository and installation files of…

Using the top utility is pretty awesome. I’ve used top for years on *nix boxes, both at home and on the job to monitor and troubleshoot system performance and issues. What’s really cool, is that ESXi has it’s own version of top installed called “esxtop”. Here’s a link to the official doc on how to…

Recently I was asked how to list out all the VIB/drivers installed on an ESXi 7.0 host. This can be easily done with the “esxcli software vib” command. But first, you may ask “what is a VIB?” It’s one of VMware’s many TLA’s (three-letter-acronyms) that stands for vSphere Installation Bundle. Think of it like a…

Let’s talk a little bit about VM CPU reservations. I recently had a question about reserving X number of CPU’s for a VM, which was required for a vendor specific virtual machine for some software that was being installed on a server. So, what exactly is a CPU reservation? To put it simply, a reservation…
