How To migrate Gen2 Windows VM from Hyper-V

This assumes you have Windows Server 2022 Gen2 VM running on hyper-v that uses gen2 with UEFI and Secure Boot - it should work for win11 but i haven't tested that. This has only tested with a vanilla windows server 2022 VM so far (three times to write guide). I will comment this gist when i manage to move one of my domain controllers.

I suggest creating a fresh test windows VM and use this procedure on that test VM long before you try this on a production VM. And repeat after me 'i will backup all VMs with snapshots AND will backup with backup application before i do this`... ok...

this gist is part of this series

ProxMox Cluster - Soup-to-Nutz

aka what i did to get from nothing to done.

note: these are designed to be primarily a re-install guide for myself (writing things down helps me memorize the knowledge), as such don't take any of this on blind faith - some areas are well tested and the docs are very robust, some items, less so). YMMV

This worked on 14/May/23. The instructions will probably require updating in the future.

llama is a text prediction model similar to GPT-2, and the version of GPT-3 that has not been fine tuned yet. It is also possible to run fine tuned versions (like alpaca or vicuna with this. I think. Those versions are more focused on answering questions)

Note: I have been told that this does not support multiple GPUs. It can only use a single GPU.

It is possible to run LLama 13B with a 6GB graphics card now! (e.g. a RTX 2060). Thanks to the amazing work involved in llama.cpp. The latest change is CUDA/cuBLAS which allows you pick an arbitrary number of the transformer layers to be run on the GPU. This is perfect for low VRAM.

• Clone llama.cpp from git, I am on commit 08737ef720f0510c7ec2aa84d7f70c691073c35d.

Encrypted Volumes in WSL2

Description

This is a quick guide on how to setup dm_crypt under WSL2 for working with encrypted volumes. I use an encrypted volume to store things like password recovery codes and 2nd factor backup codes etc. I recently switched over to using WSL2 and wanted to figure out how to enable this functionality there. This is the distilled howto for getting it to work.

Guide

First thing you have to do is create a custom WSL2 kernel. Inside your already installed and running WSL2 (ubuntu) installation:

• Install some required packages.

1. Install tools and config IPXE

# Install compiler and dependencies
sudo apt-get install -y git gcc make liblzma-dev

# Grab the source code
git clone https://github.com/ipxe/ipxe.git
cd ipxe/src

# Enable NFS support
