OK, but in my case that doesn't happen, although I guess boxes would not be
able to start the daemon as root.

Starting libvirtd as root does not create a libvirt-sock-ro owned by $USER
$ sudo libvirtd -d
$ ls -l /var/run/libvirt
...
srwx------    1 root     root             0 Mar 31 21:55 libvirt-sock
srwxrwxrwx    1 root     root             0 Mar 31 21:55 libvirt-sock-ro
...
If I change the libvirt-sock-ro owner to $USER and..
$ mkdir -p /home/tc/.local/libvirt/images
$ virsh pool-define-as gnome-boxes dir - - - -
/home/tc/.local/libvirt/images

Then...

I'm not sure why it claims " Incapable host system" as qemu will open the
iso directly without problems?
