Virtualisation from the trenches

Deploying vRNI 4.1 you might get an error: Insufficient capacity on each physical CPU.

Ovftool can be pretty awesome, but it can also be very difficult to use. I seem to have a love/hate relationship with it.

Here I will go over some common issues I have with the tool. I’ve only tested on the Windows version of ovftool.

With plenty of unfinished drafts growing, I thought I’d procrastinate even more by jumping on the static website bandwagon. I’ve migrated from Blogger to Hugo, and hosted on AWS with CloudFront. The process to migrate from Blogger to Hugo has been incredibly time consuming. Honestly I have no valid reason to change except for the fact that I’m curious to find out why many others seem to be migrating to static websites in droves.

A lot of people have probably never tried vRealize Business. As more companies want a cloud like charging model, or to show the true cost of VMs, interest in these tools is picking up. Usually vRB is deployed with vRA or vIDM, as it will use them as an authentication source. One of the great features of vRB7.2 is that it can used in standalone mode without vRA or vIDM. This is great for a POC as it can use local accounts on the vRB appliance.

Larger environments tend to integrate their monitoring and ticketing systems. Some also add automated workflows based on alarms. The problem when setting up these workflows is how do you test the workflow is triggered based on specific alarms? With thanks to William Lam for the tips, it’s possible to trigger specific events that make up alarms. It’s not a simple task (for someone who’s not a developer), but you can do some trial and error to work out how to trigger each event.
