Wasn’t one of the advantages of VMs the fact that you can slice more

Yes, that is an advantage, but that shouldn't be slicing up one computer in
to multiple very underpowered smaller computers.
Why not? That's incredibly useful.
Just to cite similar complaints I see from time to time... It irritates me
that people think it's a problem that in 2012 they can't install in a VM
that is allocated with 256M of RAM. Allocate a reasonable amount, start
over. Your host system for multiple VMs in 2012 should not have 1G of
memory.
What about my host system for 500 VMs?
Use elastic allocation. It takes a lot of ram to say "please depsolve
these 40 packages" which turns into "install these 250 (minimal)
packages". So in order to handle that kind of task (once), allocate a
large amount of ram. Once that task is complete, the actual work the
image will be doing may require a lot less ram, so you can scale down
what you allocate to that guest.
