I hope they can come up with a solution integrated into KDE where you can have apps running on a VM but appearing as a native Kwin window... Would probably need a helper daemon running on guest OS.

I know a similar thing has been done before but would be great to have upstream support from a major DE

Surprisingly Windows support this with their WSL2. It caught me off guard when i tried to run "nautilus" just for fun.

    That's because WSL2 implements an X11 client and sets the DISPLAY variable. X11 network transparency does the rest. You can do the same on Linux, as long as you're to learn how X11 arcane permission system works.

      The current architecture is wayland based, with weston and an RDP backend, and the Windows host running an RDP client. X11 apps run on Xwayland within WSL2, so ultimately rendered on the same RDP client.

      Windows implements and X11 _server_ (the client in X11 jargon is the app, which if remote works on a remote server - yeah it's confusing. You can have the X11 server on a thin client showing data from an X11 client running on a remote server). They also added Wayland support, too.

That requires a bit of hacking in general, it's not that easy to achieve that with closed source OSes. Windows supports that via RDP, btw.

You could maybe do something easier with debboostrap and chroot mounting without needing to waste resources on vm management.

None of the current solutions support this. Only if you fallback to X11 forwarding, but then it's not going to be seamless because it requires setup on guests.

Happy to be corrected if I'm wrong, this was my conclusion last year when researching again this space (since we're talking about virtualization support, thanks again RedHat for deprecating SPICE /s).

I've read that it's possible in Windows' RDP, but haven't found a Linux client/server setup that supports that.

    FreeRDP has supported this for over 10 years as a client. I don't know about non-windows servers: https://files.catbox.moe/roso8c.png

    It's also significantly more responsive than any libvirt framebuffer.

      I was pretty bullish on SPICE last year, with hardware acceleration enabled it was great. Not game streaming software latencies, but the seamless host-guest VM integration and usb/smart card redirection where features that I really desired for my workflows.
