Disclaimer: this is not something for production environments (at least, I hope for your sake, GSS should be able to fix it), but more for test or homelab environments.
Say your vCenter is broken. And I mean really really broken to the point where you can’t get the services to run anymore and you either go through a VMware GSS case and hope they can fix it. I’m good at breaking things and somehow (don’t ask) got to a point where I had broken the SSO and Inventory services and couldn’t get them back up.
I’m not a fan … Read more
VMworld Europe is next week! This is always the highlight of my year, mostly for 2 reasons: 1) all kinds of awesome new virtualization technology is either announced or released, and reason 2) my favorite; the best minds of the virtualization community gather and share thoughts, learning from each other. In the last 7 years I’ve attended VMworld, there’s a few things I picked up and I wanted to share.
There’s a LOT to do
If you wanted, you could fill up about 6 months full time with all the content that’s available on VMworld. The tricky part is that … Read more
Sorry, you actually can’t configure two Netflow targets in vSphere. 😉
HOWEVER! There’s a way around this limitation. Currently, the VDS only supports one Netflow target IP address to send NetFlow to. This limitation can cause some issues when you want to employ multiple Netflow collectors, for instance an existing Network Management System (NMS) and do a vRealize Network Insight Assessment.
What is Netflow?
I’m not going to explain Netflow in depth, but just to set the stage here’s a small summary. Netflow is a protocol that allows you to collect information about what traffic flows are going through … Read more
Certain service appliances cannot be edited manually inside vCenter. For instance, VMware NSX Edge appliances are an example of such service appliances. These VMs are managed by the NSX Manager and you shouldn’t change their configuration manually. Normally. 😉
But sometimes you need to edit those VMs. There are not many reasons why you would want to do this (as it’s heavily unsupported), but one reason might be to free up resources in your home lab (which is exactly why I wanted to do this). For instance, NSX Edge appliances come with a CPU & memory reservation placed on … Read more
I don’t post a lot from my other life, the programming personality, most of my posts come from my adventures in virtualization. I have a bit more fun writing about virtualization than I do writing about programming, plus the number of coding blogs out there is enormous. But I’ve been troubleshooting an extremely hard to pin down issue with one of my applications (WhatPulse), where there would be a latency spike every 10 seconds (or less), only when primarily connected on wifi on Mac OS 10.12 (lower versions don’t seem affected). I’ve been pulling my hair on this … Read more
The VMware Fling labs is one of my favourite things, as it brings some awesome new tech straight from VMware R&D. Some of these flings flow to the product cycles (remember the HTML5 client, now default in vCenter?). And they did it again!
Ever since I’ve seen an internal session about this product, I’ve been anxiously waiting for it to be released (one way or another). Autopology just dropped on the Flings website. Autopology is a translator between your network drawings and the real-life configuration. It is a what-you-see-is-what-you-get editor where you can create drawings of a network topology and … Read more
As a wise man said; now for something completely different. This post is going to be just that.
I received a Amazon Kindle on christmas and absolutely love it. It has replaced hauling around a bunch of physical books and made my life a lot easier when it comes to managing highlights and notes about the topics in the books (I read a lot of educational text).
Previously I had a physical notebook with me that I translated into electronic notes by hand. I use Evernote for all my note taking purposes. With the Kindle, all your highlights and notes … Read more
