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.

• OS
  • Do not use any media (we will move over out existing vdisk
  • Type: Other
• System
  • Graphic card: VMware compatible
  • Machine: q35
  • BIOS: OVMF (UEFI)
  • EFI Storage: local-lvm
  • Pre-Enroll keys: CHECKED
  • SCSI Controller: VirtIO SCSI
  • Qemu Agent: UNCHECKED

  • Finish

• 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:

    qm importdisk 101 vdisk1.raw local-lvm --format raw

    • 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.

• 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
