Looks like xvda2 is hosting the single PV constituting "VolGroup", and /home 
is a logical volume in that group. Please provide the output of the commands 
"cat /proc/partitions", "pvdisplay", and "vgdisplay".

Hmm, why would that make a difference?

The safest way is probably to create an additional partition (type LVM) on 
the free space on xvda, pvcreate(8) an additional PV on it, and vgextend(8) 
the volume group with that. You can then lvextend(8) the lv_home volume and 
finally use resize2fs(8) to grow the filesystem on it.

I'm less sure that moving the end of xvda2 and using pvresize(8) would work.
