You add more RAM or change the fraction of RAM assigned to KVM.
I can't remember if this is documented somewhere.
mdconfig(8) would have a hard time being able to tell when to reject
a request, and for testing purposes, it is a very convenient thing
to be able to create 1TB devices (and this works, as long as you
don't fill it with more data than you have KVM to).

Never attribute to malice what can adequately be explained by incompetence.
