Well, this is definitely better than a crash.  I haven't looked at that for
a long time, initially it just crashed.

Still, this current behavior isn't nice, - in my opinion it should select
microvm by default in this case.

https://salsa.debian.org/qemu-team/qemu/-/blob/master/debian/patches/microvm-default-machine-type.patch
is the outline (from more than 4 years ago), - it's a hack but shows what
I mean.
