That should be the tag to run a Pharo 7 image,
but above I see `--with-vmversion=5.0` and not sure the impact of that.

Mostly the VMs are backward compatible, so unless someone advises of a
specific counter-case
Pharo7.0.0 VM should run Pharo 6 Images.

What is the last VM/Image you saw working on Nix?
You might need to bisect from there.  I'd keep the Image the same while you
move the VM forward.
