Working lvm VG but no /dev/mapper/myvg file?

Hi,
I do:

pvcreate /dev/sda1
vgcreate myvg /dev/sda1
lvcreate -L 5G myvg -n mylv

All that works fine.  When I do vgdisplay and lvdisplay the VG and the LV appear nicely.
But check this:

ls /dev/mapper
control myvg-mylv

Why is there no devicefile for the volumegroup?  Also activating the LV's with 'vgchange -a y myvg' didn't change this.
I'm doing this in Virtualbox with the arch 2008.06 cd booted and module dm-mod loaded.  lvm2 version 2.02.36-1

Try vgscan --mknodes.

Try vgscan --mknodes.

It says 'Found volume group "myvg" using metadata lvm2', exits cleanly but unfortunately still no file in /dev/mapper
