Shrinking XenServer VDI VM Disk

XenServer doesn't allow us to do this kinda shrinking so we better recreate the vm copying all the files and recreating grub (boot) files.

1. Prepare the new disk

• Create a Virtual Disk with the final desired size (eg our running vm disk has currently 100G and we want to shrinkg it to 80G so this new disk is gonna be 80G)
• Attach the new disk to the running VM. (For this we'll need to shutdown the vm for a brief moment and power up it back again)
• Under the VM terminal we format the new disk:

fdisk /dev/xvdb #(n, p, ...) DON'T FORGET TO CREATE THE SWAPP PARTITION!!!
mkfs.ext4 /dev/xvdb1

Note for newcomers:

In the shortcuts below, "C" stands for CTRL and "A" stands for "ALT". This is a convention
used in the Midnight Commander documentation and was kept here.

You can also use "ESC" instead of "ALT", which is useful on Macbooks.
