By a "Stroke of luck", I have been running "Almost Production" Bullseye systems since halfway through the Testing Process. Any System that runs a Qemu-KVM Guest is now running on Bullseye.
I first created a Qemu-KVM Guest under Mint 20, promptly ran out of Disk Space, and so wanted to Import it to Debian (after developing a HUGE dislike of Mint 20, mainly due to their Install Process). *However*, I was unable to Import that Qemu Guest to Buster (which I was running then), because Buster refused the Import due to a lower Release Level for Qemu. So, I bit the Bullet and am Quite Happy with Bullseye (though there were a few Bumps, some of which were handled on this List, and one that became a Debian Bug Report).
So I will make my Entries, via that Github Link for three HP Systems and three Lenovo Laptops. As a bonus, I will dust off an Ancient Gaming Laptop and see how far I get, adding it too. One note: Some are upset over Github. I remain neutral, even to running a Windows 10 Guest on my HP Elitedesk 705 G1 under Bullseye.
