Interesting qemu/virt-manager bug about the "rotational" attribute on vi

A virtio-blk disk which is backed by a raw file on an SSD,
inside the guest shows rotational = 1.

I assumed that qemu must have a "rotational" property for disks and
this would be communicated by virtio to the guest, but qemu and virtio
don't seem to have this.  Pretty surprising!  Is it called something
other than "rotational"?

virt-top is 'top' for virtual machines.  Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
