Answer:
  1. Give desired size of the Hard-Disk
     #check if the root disk is cosumed 100%
      sudo dh -h
     # Increase the Physical Volume (pv) to max size
         pvresize /dev/sda3

2. Inside the VM, do the commands:
     # Expand the Logical Volume (LV) to max size to match

3. Expand the File System itself:
   # Expand the filesystem itself
     resize2fs /dev/mapper/ubuntu--vg-ubuntu--lv
