[one-users] problem when attachin volatile disks

When I add a new disk to a running instance, I type raw (or anything else)
in the FS format, qcow2 in the driver field and choose vd as device prefix.

I then have an error that the disk.2 is not a qcow2 format. Qemu-img shows
that in fact it's a raw format image that have been created. So I retry
with a raw format and then it works. So how do we attach a disk in qcow2

Moreover, if I choose read only, I still can write/format this disk in the
VM. Is it normal?

best regards,
