I haven’t seen this recommended anywhere but you could get a beefier computer, slap on windows server and use Remote Desktop session host that will allow multiple users to connect. You can get a 5 user license for about $250 from a quick google search. You can enable gpu rendering for rdp but if that does not work you can get a slightly older version of windows server and use remote fx. Pair that with a vpn server install and now everything will be in one place.

Múltiple vms can still share that one core. Unless you’re crunching numbers in a vm, the core usage is likely not reaching 100%, and it can still be shared between vms. It does not exactly translate to 1 to 1
