There does appear, as was pointed out, that there is a confusion between VM (virtual machine) and LVM (logical volume management).  If you are using LVM, I strongly recommend that you do not use GRUB2 on that partition.  It is almost impossible to repair (I found it to be impossible) since it requires a way to mount those partitions before being able to repair it, and no repair kits do such.
