For the RAM, each VM, and the host, needs its own chunk of RAM. Devote 4GB to each, and 16GB goes away rather quickly.
All depends on exactly what OS and applications are running.
Here is my 32GB system, running simultaneous 4VM's.
Win 10 Pro, Server2016, Linux Mint, Ubuntu, and the host Win 10 Pro.
Out of 32GB, 10GB spare.
And yes, you need a good CPU. Mine is an i7-4790k.[/
Thanks my heart was saying 16gb my head 32gb.
Do you think I can get what I need for £1000?
Thanks Tim
