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

Caveats!! a human brain must be used !!!

First, get ALL your access IPs from your HTTP server

cut -d' ' -f1 /var/log/nginx/access.log | sort | uniq > /tmp/all_ips

Now we can use a docker image to have the IPtoASN API https://iptoasn.com/ running locally

docker run -itd --name my-iptoasn -p 80:53661 ilyaglow/iptoasn-webservice

I've been playing around with a Raspberry Pi hosted with Mythic Beasts and wanted a way to keep a large number of infrequently-accessed files on the server. A cost-effective place to store such data is on Amazon S3. After looking around at ways to mount an S3 bucket on the Raspberry Pi and have it appear as a regular filesystem, I came across s3backer. This provides a single file, divided into blocks, each of which is stored as an S3 object. A filesystem is mounted onto this file using a loopback mount. This setup has many benefits which are explained well in the README. Here's how to set it up on the Raspberry Pi.

I'm going to assume that you have an S3 bucket mybucket created and a user with credentials to access it. Although not explicitly specified, some of the commands below need to be run as root.

First, install prerequisites (the first line is
