ESXi on my old pc.I am sure it supports ESXi 6.7.
How are you "sure" this is the case, given that ESXi doesn't even support personal computers?
If you're just getting started with ESXi, a couple things to recommend:
- Use the free Hands on Labs (hol.vmware.com). It'll give you an instant lab you can repeat as much as you'd like, and all the heavy lifting is done.
- Run ESXi in a VM on Workstation. More work, and not all systems will allow it, but it'll give you something.
- Get hardware which is known to run ESXi. Even if it's not on the HCL, many consumer-type boxes do work including Intel NUCs. This is more of an investment and may or may not be right for you.
