# 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
# - Omit creation of EFI disk upon confirmation of non-EFI BIOS
### PREREQUISITES ###
# - 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.
