When we first built our Windows 2016 template, we tested hot-add RAM and hot-plug vCPU. Both worked and so we enabled it in the template. However, today when we tried to hot-plug a CPU on a live server, it crashed. I built a few test servers and it consistently crashes now whenever we hot-plug.
Now in full disclosure, our template have been updated many times - and I don't believe we test hot-plug after every change. So I am pretty sure it is some change we recently made that caused it to break...including VMware hardware version 11. I am pretty sure we have updated to 11 since the original template was developed. I am betting that is the problem.
Has anyone else seen this problem and know the cause and/or solution to it?
Thanks
