Deploying VMware Appliance for Folding@Home With Ovftool

Recently VMware released a Fling of the VMware Appliance for Folding@Home.

It’s great to see the VMware community coming together so quickly to help out.

As part of my love/hate relationship with ovftool, here’s a few ways you can deploy the VMware Appliance for Folding@Home using ovftool.


If you try and deploy vRA8 into VMware Cloud on AWS, you’ll get this error:

vRealize Network Insight (vRNI) Tips

More customers are embracing the suite of applications provided by VMware in managing their environment. I’m seeing customers with vRealize Network Insight (vRNI), but a lot still don’t appreciate all the things it can do.

Leaving it for a few hours didn’t make any difference, and I was unable to alt-F1 and log into the console, as when the error message flashed up, it would reset the login process.

Using Ovftool

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.

Migrate to Hugo

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.
