Quick step by step guide on how to increase HDD size for a VM
Steps required are,

3. Add the new partition to total partition to increase the disk space
# /sbin/pvcreate /dev/sda3 # Modify sda3 to the last sda
# /sbin/vgdisplay | /usr/bin/head # Check the VG Name, and LV Name which we are going to extend
# /sbin/vgextend vg_centos /dev/sda3 # Modify sda3 to the last sdan
# /sbin/lvdisplay
# /sbin/lvextend /dev/vg_centos/lv_root /dev/sda3 # Modify sda3 to the last sdan
# /sbin/resize2fs /dev/vg_centos/lv_root
# reboot
