Since vSphere added the ability to have oddly numbered non power of two vCPU configurations, I’ve wondered what it’d be like to run a VM with an odd number. Will Windows react oddly? etc?
I also had some curiosity around doing similar for non standard amounts of ram (non power’s of two or multiples of 1024).
When changing resources on my vCenter VM I decided to take the plunge, Prime numbered CPU’s and 2PI * 1024 (rounded) MB of ram. Into it a few months now and so far so good!
