[CentOS-virt] Resizing disks for VMs

Hi,
Is there a way to make a PV xen guest aware of a size change of the host 
disk? In my case I'm talking about a Centos 5.3 host using logical volumes 
as storage for the guests and the guests running Centos 5.3 and LVM too.
What I'm trying to accomplish is to resize the logical volume for the guest 
by adding a few gigs and then make the guest see this change without 
requiring a reboot. Is this possible maybe using some kind of bus rescan in 
the guest?

Regards,
