[Xen-users] Can't mount across doms

I am trying to share a disk (/dev/hdb7) across dom0 and my domUs as 
/zen/local.But me creation of the VM fails with:

Using config file "subversion/subversion.xen".
Error: Device 833 (vbd) could not be connected.
Device /dev/hdb7 is mounted read-write in the privileged domain,
and so cannot be mounted read-only by a guest.

According to my /etc/fstab on dom0 I am mounting this as read-only. And the 
output of my mount command also confirms this (this is shown below). Any idea 
what I am doing wrong? This isn't a showstopper for me, it would just be neat 
to not have to recreate everything across VMs. Otherwise I am incredibly 
impressed with this software.
Oh and BTW xm info produces:
