====== Install Pi-hole on Ubuntu as Proxmox Virtual Machine ======
I have yet to install Pi-hole on Proxmox from scratch... I converted the existing Unraid VM to Proxmox. The below steps outline that process and I hope to update this page with instructions for a fresh install. If not, do it on Unraid and then follow the below :D. If you are attempting to install a fresh copy, use the below Proxmox Settings and then upload the iso and go from there... should be straight forward.

    * Finish

===== Move virtual disk over =====
  * Erase old disk
    * Go to Datacenter -> node name -> windows vm
    * Click on Hardware
    * Select hard disk to remove
    * click Detach
    * click Remove
  * Import new disk
    * move the new disk to a location that proxmox can see it (see adding share in the install proxmox section)
    * ssh into proxmox or open a shell (Datacenter -> node name, then click >_ Shell
    * go to the folder of that new disk (cd /mnt/pve/unraid/ for example)
    * rename the image to a .raw file
    * type the import command: <code>qm importdisk 101 vdisk1.raw local-lvm --format raw</code>
      * where 101 is the vm id and local-lvm is the location.
    * after complete go to the vm -> hardware and double click on the unused disk and click Add
    * go to Options -> Boot Order and set the boot order to the top.

===== Cleanup =====
  * some IP address and hi availability conf files need to be changed to account for the new Ethernet interface name (eth0 to enp6 or whatever)
    * this was in multiple locations
