Easy Resize Linux KVM on Proxmox VE 3.3

Ok, i lied, there is no easy way to resize kvm but it's pretty fast if you know what you are doing. Finding Proxmox VE resources isn't very easy since not many people are actually writing this to share their knowledge across. I figured that i should write down how i resize my KVM environment on a Centos 6.6 environment that i have for a KVM vm to better illustrate how this can be done quickly

Requirement

Before i start let me explain what you need to have on your hard disk setup within your Linux VM environment. Your harddisk must be setup with LVM also known as logical volume manager. At least this is how i setup my hard disk, if not, you will need to do a huge around of crap just to resize your KVM environment.
