HyperV added

Only enabled so far for Archlinux and CentOS. Also, needed to change file endings on ALL THE THINGS. Might or might not show up.

 # Building on Windows
 
-1. Install Cygwin with packages; I install to C:\Cygwin64 as per defaults
-  * python39
-  * python39-setuptools
-  * python39-cryptography
-  * python39-pip
-  * openssl-devel
-  * libffi-devel
-  * python3-devel
-  * zlib
-  * zlib-devel
-1. Inside of Cygwin
-  1. Create a venv *with system packages* enabled
-  1. Install windows/ansible-requirements.txt into the venv
-  1. Update the path in ansible/hyperv-wrapper.py to point to your VENV
-  1. Execute pyinstaller --onefile ansible/hyperv-wrapper.py
+1. Be sure that Hyper-V is installed and enabled on your system
+1. Download and install packer.exe to your system, and add the folder it is in to your user's PATH environment variable
+1. Download the [Windows ADK](https://learn.microsoft.com/en-us/windows-hardware/get-started/adk-install) being sure to select
+   at the least "Deployment Tools" from the feature set.
+  1. To see more details, including a walkthrough, check [this web page](https://www.makeuseof.com/windows-iso-folder-command-prompt/)
+  1. Be sure to add the install path for the Oscdimg tool to your Windows PATH.
+  1. On my system, that path is "C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Deployment Tools\amd64\Oscdimg"
+1. Open PowerShell (on my system I had to run as administrator), and ensure that you have access to python
+  1. If you type "python" at the prompt and do not have it installed, it should prompt you to install from the Store
+  1. Do not install the version downloaded from the Internet unless you know what you're doing
+1. Create a venv `python -m venv .venv`
+1. Activate it `.\.venv\scripts\Activate.ps1`
+1. Install the packages in requirements-windows.txt
+1. Try a build
+  1. You can execute directly with the `packer` executable, if you want
+  1. If you want to wrap up standard options, or build multiple versions/distros at once, use the `build.xsh` file
+  1. `xonsh build.xsh -d <distro> -b hyperv-iso.x86_64 -v`
+  1. You can substitute out any of the options with `-a` to build "all" targets that match
+
+### Troubleshooting
+
+Personally, I had issues where the Hyper-V networks were untrusted by Windows. This can manifest itself as the VMs that
+need to download Shell files from the Packer http server (NixOS, Archlinux, and others) being unable to reach the
+HTTP server on the host. To rectify this:
+
+1. From the Windows Start/Search type "Firewall"
+1. Click "Allow and App Through The Firewall"
+1. Click "Change Settings"
+1. Scroll all the way down to where you find the entries for the packer-hyperv plugin
+1. Ensure that all such plugin versions have the box on the left and BOTH boxes on the right checked
+1. Click "Ok"
+1. Try running your install again.
+
+I also had an issue with my VMs getting a different IP address each time they booted, which means that the IP detected
+during install is not the same one during provisioning. In order to address this issue I had to setup a static IP
+address for the MAC address "00:00:de:ad:be:ef" in my network DHCP server and tell my machines to use external networking
+to reach it.
+
+1. Open Hyper-V Manager
+1. In the right hand side, click "Virtual Switch Manager..."
+1. Select the `packer-x86_64` switch
+1. Set connection type to 'External'
+1. In your DHCP server, assign a static IP address to MAC address "00:00:de:ad:be:ef"
+  1. Personally, I use dnsmasq and my subnet is 10.42.2.1/16 for DHCP, so the appropriate config line is `dhcp-host=00:00:de:ad:be:ef,10.42.2.254`
+  1. The actual IP address you assign is unimportant, and if you need to spoof a different Mac address, edit the file `sources/hyperv-iso.pkr.hcl`
