Hello all,
i faced quite the same problem with lvm 2 + xen 2.x
i resized in dom0 a partition used in domX. The partition is formated in 
  XFS format.
I issued an lvm resize in dom0, it showed that the volume was extended, 
so i try an xfs_growfs on the mounted partition but nothing append ... 
In dom1 the partition was seen unchanged ...

I stopped the dom1 domain and mount the partition in dom0 (a xfs 
partition must be mounted in order to be extended ..) but xfs_growfs saw 
  the Filesystem smaller than it was.
After unmounting the volume and recreating dom1, i have been able to 
resize the FS in dom1
Quite strange ?
I've try to do the same on a volume used direcly in dom0 and in this 
case there was no prolbem (lvm resize + xfs_growfs were like a charm ...).
HTH !
Matthieu
