I'm going to let you in on a trick I do all the time for quick and dirty
VMs, ready
touch vmimage.raw
truncate -s 32G
ls -l vmimage.raw

Then use that as storage for the VM. It is a thin provisioned raw image.
Or, if you have ZFS

It's the same virt-manager with the same capabilities. I think it

I do note that it seems Raspberry Pi 4 apparently can run real KVM...

You can't make a general argument about a specific example. I have an 8
core AMD FX with 16G ram. It isn't running ZFS, but it is running an MD
RAID5 with 5 4T SCI disks.
I'm running 5 VMs on it: a database VM, a mail server, a web server, a
webproxy/firewall, and a dev server. The machine is down
