# To-do:
# - Add ability to choose between local-lvm and local-zfs
# - Find way to carry over MAC
# - Attempt to find way to fix networking post-migration automatically
# - Get script to pull specs of ESXi VM and use them when creating Proxmox VM
# - Add functionality to remove old .ova files from local machine
### PREREQUISITES ###
# - Install ovftool on the machine you are running the script on
# - This script assumes you have key-based authentication already configured on your Proxmox host. If you do not, add your public key
# - You must hardcode the variables for your esxi and proxmox IP, user, etc. I previously had the script prompt the user for input every time but that isn't efficient when migrating multiple VMs in quick succession
# - Install ovftool on the Proxmox host
# - Ensure you have key-based authentication configured for any remote connections needed
# - Hardcode the variables for your ESXi IP, user, etc.
# This script is intended to be run on your Proxmox host
# Function to get user input with a default value
