Attach / detach or a simple reboot of the guest will work, by causing a 
reprobe of the disk sizes.

However, this strictly shouldn't be necessary - older versions of Xen could 
actually get the guest to reprobe disk sizes.  This still required an 
unmount / remount in the guest, but in principle it looked like even that 
shouldn't be necessary if you were merely growing the device.

Maybe this is something that should be flagged to be re-added?

Cheers,
Mark
