I'm not saying you need 64GB, of course. I only have that much because I
need to run multiple VMs simultaneously.


okay, I run VM's but only have 8 cores. So I give 4 to host and 4 to guest.
If you run multiple VM's how do you allocate the cores?


Extreme oversubscription. My CPU is an i7-8700, so 6 cores and 12 logical
processors.

The Linux VMs each get 2 cores, except for some of the specialty stuff like
virtual routers (dd-wrt) and firewalls (pfsense) that need only a single
core. The Windows VMs each get all 6 cores, except for the older stuff: XP
gets 2, 2000 and 98 get 1 each. I also heavily oversubscribe the RAM and
just let VMware figure it out. It's the lazy way to do it but it works very
well.

Yes, I have 8G of memory and I want 16 so each host/guest gets 8G
It's a bit thin running a VM with 4G some days.


Agreed, but it depends on what it is and what you're doing with it. My VMs
don't do any heavy lifting, but I frequently need to have 12-20 running at
the same time to model a customer's network so I can demo a solution to
whatever they hired me to do. I sling some traffic around within my virtual
lab to show proof of concept, but that's about it.
