Hi Greg,

If your only problem with CentOS 8 is the support end, why not just switch
the system to Oracle Linux 8 or another clone or even Red Hat EL with one
of the new licenses, if they fit your needs?

Moving the whole setup to VMware seems a bit overkill to me as you likely
have to learn a completely new system and deal with new problems.
