Sorry for the late response.

Besides <cpu> setting, what types of features do you see tweaking for 'Full
host' vs 'easily' vs 'normal'?

If the main differentiator is 'how migratable is this VM' I don't like the
idea of putting that into the New VM wizard, since I think 99% of virt-manager
users don't care about that, and migration is a difficult concept with a lot
of VM config caveats, plus it usually requires host configuration outside of
virt-manager to get working so it's unlikely to be something that 'just works'.

However I'm more open to a kind of migration vs performance setting in the
Preferences dialog that determines the default New VM setup. But to discuss
that we should start with a list of features you see enabling/disabling

Thanks,
Cole
