Importing Legacy Windows XP or Windows 2003 from Virtualbox to Proxmox

Problem Statement:

  • I have an old Windows 2003 32 bit server running in Virtualbox.
  • Since Virtualbox is under decommissioned, it is intended to be migrated to Proxmox VE

Before Migration or export of VM from Virtualbox, following .reg file is required to be installed on Windows 2003 server to avoid IDE incompatibility and avoid BSOD or Blue Scree of Death

Download file: https://pve.proxmox.com/mediawiki/images/f/f5/Mergeide.zip

Once the registry file is imported, you can shut down the virtual machine and start exporting.

You can follow my earlier post of https://tweenpath.net/convert-virtualbox-vm-proxmox-ve/ and continue.

This worked on Windows 2003 the same will work for Windows XP VM.

Build PPPoE server using PfSense

Before building a PPoE system, it is estimated to assume that we’re building it on the following principal and prerequisite conditions-

  1. It’ll be a NAT PPPoE router
  2. At least 2 Interface we’ll be needing- 1 for WAN/Internet/Uplink and the other for LAN/PPoE user.
  3. A reserved LAN IP for PPPoE server itself (other than the LAN IP)
  4. Disable DHCP service if it’s running
  5. Prefereably disable DNS Resolver and enable DNS forwarder
  6. As of this pfsense/Netgate tutorial is being written the version is 2.6
  7. A

For easy understanding here goes my mockup instace WAN and LAN IP-

  1. WAN IP- 114.130.95.196/27, 114.130.95.193
  2. LAN IP- 192.168.1.1/24
  3. PPoE Reserved IP- 172.16.16.1
  4. DNS- 8.8.8.8
  5. LAN port is connected to the LAN switch or alternativey you can connect it to your PC
  6. Assuming you have an operting pfsense using static IP endpoint and you can use internet using static gateway configuration.
