Could it be that your domU kernel has to re-read the partition table? Maybe 
the domU kernel does not know that you have resized the "partition" but the 
dom0 kernel does (because you used lvextend in there).

sfdisk --re-read

should make your kernel reread the partition table (if you have sfdisk...).
