I'm using MXLinux 25, which is based on Debian 13, and I've set up some virtual machines in Virtual Machine Manager for both Debian 12 and 13. Unfortunately, I'm experiencing a lot of lag with these VMs. I've installed the VirtIO drivers when I configured a Windows 10 VM, and while it still lagged, using remote desktop helped a bit. I'm wondering if the setup with VirtIO drivers for Windows 10 is causing the performance issues in my Debian VMs, or if there's something else I might be overlooking.

The configuration of one VM doesn't typically affect the performance of others. Most desktop environments rely on 3D acceleration, which can lead to issues without GPU passthrough or by installing the `spice-vdagent` package. You might want to give that a try and see if it helps!
I've heard GPU passthrough can be tricky, so I've been hesitant to try it. I haven’t looked into spice-vdagent, so I’ll definitely check that out. Thanks for the suggestion!
