WTF!? - Powering on a virtual machine fails with the error: A general system error occurred

This can by far be one of the most frustrating error messages you will run across in a vSphere environment.  I was at a customer site yesterday and the customer ran across it while I was working through some other things.  He asked if I could fix it for him.  :) I immedieatly dove into the issue and started looking at the problem he was having and the error message was very generalized in nature.  "Powering on a virtual machine fails with the error: A general system error occurred"  I wasn't able to change any settings on the VM…

The Cloud Orchestration Layer is Changing

With the recent purchases of a couple key companies within the cloud orchestration space I felt it was time to write about it.  The companies I am referring to are Cloupia, who was purchased by Cisco in December and Dynamic Ops, who was purchased by VMware in July.  In my opinion these companies had such a huge head start on where both of their parents were at the orchestration/cloud layer that there really wasn't a way for the parents to catch up without the purchases.  Thankfully they picked some bright stars to buy. We know that both Cloupia and…

vSphere 5 Upgrade: PSOD for vSphere 4.1.0 Hosts

I had a customer get ambushed by this last week and wanted to put this out there so hopefully no one else will run into this huge problem.  There is a VMware KB article out regarding the issue, however none of the release notes or upgrade documentation has been updated to reflect the information in the KB article.  Bottom line: DON'T UPGRADE VCENTER TO V5 IF YOU ARE RUNNING VSPHERE 4.1.0 (NO UPDATES) ON YOUR HOSTS! The KB article can be found at the link here: clicky Most of us have read through the upgrade guide for vSphere…

vCenter 5 Database Move: Update the tomcat DB pointer

Ran into a weird issue the other day and was totally perplexed.  I moved a vCenter database from one SQL server to another, as I have done numerous times before without issue, but this time something else cropped up.  The old SQL server kept receiveing login attempts from the vCenter server.  What?!?   My DSNs for vCenter and Update Manager had been changed to point at the new DB server.  All apps and plugins that query vCenter use these DSNs, WTF is going on? The "VMware VirtualCenter Management Webservices" service utilizes tomcat to connect…
