Add Windows 11 VM Docs

[kokomo123]

Per https://discussion.fedoraproject.org/t/tutorial-how-to-create-a-windows-11-vm/147506/ there were suggestions to add this to the docs of Asahi Linux, and I thought since it hasn't been added, I have sufficiently created a guide to the best of my ability using markdown and some copy/pasting from the forum thread. Feel free to edit/adjust it as the community / maintainers see fit as this seems decent enough, but i'm all ears for contributing to make it the best community windows 11 vm guide as it can possibly be. :)

I haven't tried to follow the guide yet but it looks good, nice work! 👍

I'd just like to suggest adding an option to set this up using QEMU+libvirt instead of plain old QEMU.
Many users such as myself prefer to use that front-end, if you'd like I can add this change to your PR.

[kokomo123]

That's totally fair, i'm flexible with you adding that change :)

[Zlendy]

Ok, I'll work on it in my free time and add it as a suggestion change to your PR when it's ready.

TYVM!

mkdir windows11 does not close its code tag

[Zlendy]

I feel like I almost got it, but there's some weird issue with libvirt that prevents me from running any VM, apparently.

qemu isn't the issue here because your script worked flawlessly.

[kokomo123]

That's good :) at least qemu is running for sure

[kokomo123]

Any update on libvirt problem? @Zlendy if not, i can try to replicate.

[Zlendy]

Unfortunately not, the error message is this:

BdsDxe: No bootable option or device was found.
BdsDxe: Press any key to enter the Boot Manager Menu.

This seems to indicate that the cdrom is not loaded correctly. But it's weird because I've done this so many times on x86-64 computers, this is the first time I've seen this lol.

To replicate it just create a VM with virt-install or virt-manager, any libvirt frontend should be able to replicate this.

[kokomo123]

Alright, imma create a arm64 debian vm on macOS to replicate then

[Zlendy]

macOS works fine, this only happens in Asahi Linux using libvirt

[kokomo123]

Oh, well.. lemme install asahi linux then 💀

[kokomo123]

Update: downloading a debian 13 ISO worked, and it booted successfully. I am downloading the arm64 image of windows 11 currently on Asahi.

[kokomo123]

Update: yeah it seems EDK2 firmware halts and doesn't load the image. I think we would be fine to just include the qemu instructions, and say libvirtd is unsupported at this time.

@Zlendy internal error: Child process (dmidecode -q -t 0,1,2,3,4,11,17) unexpected exit status 1: /sys/firmware/efi/systab: SMBIOS entry point missing
Sep 10 07:57:23 libvirtd[4831]: operation failed: Cannot find CPU model with PVR 0x025
This is probably why libvirtd isn't working, /sys/firmware/efi/systab doesn't have anything in it. Thus, the firmware doesn't know what to do. I hope this can be fixed, otherwise now, I am just going to push a slight edit to the docs saying "virt-manager is unsupported, please use qemu", as I have discovered through researching. https://www.reddit.com/r/AsahiLinux/comments/y7hplo/virtual_machines_on_asahi_linux/, and with default settings, toying around with the CD-rom device too. I wish libvirtd had better support on Asahi rn.

[Zlendy]

I never would've guessed that was the problem, you deserve a medal 🏅

[Zlendy]

LGTM!

@Conan-Kudo @chadmed Pinging just to make sure this is all LGTM, if there's any adjustments ya'll think is needed, feel free to let me know 👍🏻
