 That terminology is totally exotic. You're probably mixing up NVMe and
NVRAM.

   Um ... nothing remotely "exotic" about it.

   It's all the SAME THING ... just different acronyms.

   4 gig ? DO-able, but kinda TIGHT. The 32g unit ought to
   be better. As for "gobs" ... depends on WHAT you're running
   on the VMs. Some apps/servers are more memory-intensive
   than others ... ArcGIS for example.

 Of course. Any software is not going to be smaller on a VM than on
bare metal. But you can't blame that to virtualizatin.

   Not "blaming" it - that's just How It Is. If you
   run a big busy DB as a VM then you're gonna have
   to provide the CPU/mem so it'll run properly.

   Anyway, mem is still fairly cheap, so why buy 4g when 8g
   barely costs any more ?

 Because housing machines can get expensive pretty quickly. The APU I
am running those five VMs on comes with 4 GB and is not expandable.
And it does the job silently and doesn't get hot.

   What's your fix - "go cloud" ??? A lot of us KNOW better,
   how BADLY that can go wrong.
   And with Russia/China/NK initiatives it's gonna go
   all the wronger all the faster.
   In any case, your 4gb solution sounds kinda "marginal", but
   of course that depends on what your VMs are/do and whether
   you run 'em one at a time or all together.
   Even these modern mini-boxes (search Amazon, there are a
   huge selection of variants) are - with Linux/Unix - more
   than adequate for a large number of "common" uses. Those
   ultra-i9's ... well ... maybe if your main thing is
   playing games. That's valid - but "biz" has a different
   spectrum of needs. With -ix, even a modern i3 can host
   like an entire airport booking system, multi-company, and
   be pretty snappy. Each airline gets its own VM.
