Given with "VMware VM" you mean a virtual machine on an ESX(i) system
and that the admin just increased the disk size for the VM, you will see
the additional disk space using fdisk / cfdisk as unallocated space.
Either increase your LVM or create a new partition.

Depends much on the purpose of the additional space. Generally LVM makes
it very easy to increase any of the existing LVMs / mountpoints.
