Variable Init Phase :
- changed VDI variable name to latest Ubuntu version name
- changed VMNAME to correct format k_grok-<username>
Host configuration phase + VM creation phase + VM storage config phase :
- tested and seems to run ok

- I have updated IP address that's used for vboxnet1 set up to 192.168.57.#  on line 81, instead of 192.168.56.#,  to make sure that if user has vboxnet0 set up on their computer, that the same IP address is not being used to set up vboxnet1

- I changed VM name to k_grok-group5

- I have run script few times and tested all features:  
        new VM works and starts succesfully
        user can go online via NAT only from within VM
        user can ssh from the host/laptop into the VM
