What you want to do is perfectly possible. I've ran games that way using Windows 7 VM.

Originally posted by @R+5:

also, which (free) vm can i use for that? and which could be a good step by step guide "for noobs" (at least for vm stuff and related themes).

I personally feel that both Xen and KVM are good solutions but Xen offers probably the best experience once configured correctly. KVM is bit easier to setup but might not be as performative or secure.

See: https://wiki.xenproject.org/wiki/Xen_VGA_Passthrough
And: https://wiki.xenproject.org/wiki/Xen_Project_Beginners_Guide
As well as: https://wiki.gentoo.org/wiki/GPU_passthrough_with_virt-manager,_QEMU,_and_KVM

...for example as a starting point. I feel that for new users OpenSUSE provides pretty good host OS for Xen setup since you basically just install Xen using graphical tool called YaST and it will magically work for the most part with a sane initial configuration: https://doc.opensuse.org/documentation/leap/virtualization/html/book-virtualization/part-virt-xen.html

But Fedora can also do it and since Nobara is based on Fedora it should have all the necessary pieces of software available... https://wiki.xenproject.org/wiki/Fedora_Host_Installation

However let me put a word of warning... Under any circumstance do not play the popular multiplayer games such as Valorant, Rainbow Six: Siege and Apex Legends using this kind of VM setup. Especially not in KVM.

You will risk your account being permanently banned if/when Anti-Tamper/Anti-Cheat will inevitably detect that you're using VM to play these games even if you're not cheating. Xen with proper configuration might be able to evade this kind of detection (since it uses proper hypervisor approach) but I wouldn't probably do this in it either. These games (and many other multiplayer games) prohibit this in their license agreements explicitly as well. See: https://areweanticheatyet.com/

Edit: I should add that many of the links here on how to do this are bit outdated. You need to do some research on your own. But it's not too difficult to get things done with a little bit of effort.

thanks @dekonega.

do you know also where i can start learning about wake-on lan (turn on a "remote pc", my desktop, so i could play a game using a mini-pc or something else as "client")?

i think i dont play any multiplayer game that would be at risk for bans, but will check if "conan exiles" is one, since i want to check how that one runs in a vm (even if im currently not interested in the mutiplayer-online aspects, only in the base building mechanics which can be played offline).

apart from that, i was considering if using win11 ameliorated could allow running android apps directly, so rather than installing an android emulator in linux that could work too for a few apps and games.

the main reason in need windows is to use a couple of sound editing programs, maybe an image editor, and a few programs and games that dont work well or at all in linux through proton.
