# Description: This script will automatically copy the necessary GPU drivers from your current host machine into a Hyper-V Virtual Machine
# so you can pass through the GPU to the VM. You should run this whenever you update your graphics drivers on the host.
#
# Author: ThioJoe  --   https://github.com/ThioJoe
#
# Note: Currently this only works for Nvidia GPUs. But it does support if you have multiple GPUs.
#
# OPTIONAL ARGUMENTS:
# -debug  |  Enables debug messages that pause the script for each step (No additional string required, just add -debug)
# -name   |  Sets the virtual machine name so it doesn't need to ask

Hey guys, me again. After a day of testing and fucking with VMware/Proxmox/The VM itself, i finially got it working!!!!

I just wanted to come back and make another post to firstly thank everyone who helped me figure this out. So many awesome suggestions. Moment of silence for those awesome people and the sheer amount of people at that! Glad to be a part of this community. Couldn't have done it without you guys!

Now, on to the second part. As i promissed, i am going to walk through all the steps i took to go from a VMware Player 12 VM to a glorious Proxmox VM.

Does it boot (AKA, bricked from the get-go)? Lets find out!

1.0. I first shutdown the VM in VMware Player 12 and copied all .vmdk files to an external HDD so i can start the prod server up again since player didn't have a export function. Technically there is a [ovf exporter tool](https://developer.broadcom.com/tools/open-virtualization-format-ovf-too

TL;DR A complete feature-set bootloader for ZFS on root install. It allows booting off multiple datasets, selecting kernels, creating snapshots and clones, rollbacks and much more - as much as a rescue system would.

<#  This PowerShell script can simply be copied over to a "PowerShell IDE" window, and then ran for as long as you want.
    The time this script remains active (sending mouse events to Windows so it things you're "still there", is the number
  of iterations on line 6 (default: 200) multiplied by the number of seconds on line 11 (default: 290).
