So thanks to William Lam, I thought I would try to build out my homelab with the nested ESXi appliance. Things seemed to go smoothly as I was able to download the ova file and then import it into my vCenter. Then I turned it on…
Everything seemed good to go, the packages were loading and it was a breeze until this occurred
Needless to say, I spent some time querying my favorite search engine Google for the answers. After a little bit of data mining, I finally found this Arima NM46X installing ESXi ‘Unsupported microcode level 0x01000039’ on serverfault.com. Essentially it said to add the
skipMicrocodeCompatCheck attribute after pressing Shift+O on ESXi boot. This is what the line looks like before adding the attribute
And this is what the line should be
To keep the setting so you don’t have to press Shift+O every time the esxi host reboots, SSH into the box after it boots up and then run this command:
esxcfg-advcfg -k TRUE skipmicrocodecompatcheck
So after completing this, I have 3 new nested hosts up and running in my home lab to play around with.
