• Mouse movement in 3D games running in KVM VMs is not correct or usable

    From George at Clug@21:1/5 to All on Sat Dec 7 08:40:01 2024
    Hi,


    First thought, if someone using Debian Testing, please check to see if "alien-arena" is available for installing. In my Debian Testing
    environments, only "alien-arena-data" was available but not
    "alien-arena", which seems strange???



    Reason for this email: Mouse movement in 3D games running in KVM VMs
    does not work correctly.



    I really like using VMs but at times I also find this frustrating. 
    (Please explain how, if I am wrong in my assumptions)



    If I have an Nvidia card, VMWare Player/Workstation can emulate 3D
    graphics. But not in KVM



    If I have a Radeon card, KVM can emulate 3D graphics via VirtIO
    drivers with OpenGL support. But not so  for VMware
    Player/Workstation.



    Maybe if I had both in my computer?  I have not tried this.



    A second frustration has been with KVM is that I cannot get the mouse
    to work correctly when I enter the 3D game. Tested with Alien-Arena,
    Minetest and Minecraft.


    For anyone using GPU passthrough, how do you get the mouse to work in
    3D games? Do mice just work when you use GPU passthrough?



    Support for vintage Operating Systems is often lacking too. Maybe
    Windows 7 is now vintage too, as I was unable to install the latest
    VirtIO drivers in my Windows 7 VM.



    But since I would not be able to write virtualisation software myself,
    I should not complain too much. I just thank those who have put in so
    much hard work which allows me (and others) to run the VMs for running
    and testing general server and desktop software.


    George.
