ESXi and Nutanix post configuration using PowerCLI

For years I’ve been using kickstart for the installation and configuration of VMware ESXi. Who doesn’t know William Lam kickstart blogs?
Using kickstart, I can do a fully unattended installation and configuration of ESXi.

But, when using an HCI solution like Nutanix, host are pre-installed (foundation) with VMware ESXi, and the Nutanix CVM runs (as a VM) on the hypervisor. So you don’t need to install ESXi separately. 
If you want to use one script to configure VMware ESXi and the Nutanix CVM. Which includes configuring options like changing default passwords or adding a ESXi host to a VMware Distributed vSwitch, kickstart using esxcli and bash command, isn’t flexible enough anymore.

After a little digging around in different options, I decided to use PowerShell. This enables me to create an configuration script, where I can configure 98% of all the setting I want. This script can run on your laptop or on a management server.

VMworld 2018 US: My thoughts

It’s has been almost a week since VMworld 2018 US. And I have to say, what a week!

I’ve spoken to so many people. Old friend made some new friend, and spoke to a lot of vendors on the Solution Exchange.

In my opinion, this VMworld was great! Not because of all the new exciting things that were announced. 

But more because most of the announcement where about product upgrades and feature improvements.

I like the fact, VMware is taking his time, to make his product more mature (not that they aren’t mature already, but you get my point).

Let me recap the most important thing, that struck me.

Migrating virtual machines using PowerCLI

In my current role as a VMware architect, I architected a greenfield VMware vSphere 6.5 environment.
The ‘old’ environment, who I architected 4 year ago, is VMware vSphere 5.5. As the old environment was never updated, the time and risk of upgrading this environment was too high. That’s why, we decided to go for a greenfield installation.
As the new environment was accepted by the customer system administrators, we had to migrate 700 virtual machines to the new environment.
The old environment was using NFS datastores, as the new environment is using hyperconverged.
As the old environment was vSphere 5.5 U1, we weren’t able to vMotion virtual machines to the new cluster, using Cross vCenter vMotion.

To make the migration as painless as possible, I create a PowerCLI script to do the hard work for us.
