If you want a proper kvm, see the offering from level1techs/wendell (not affiliated, just a satisfied customer) at https://www.store.level1techs.com/products/hardware

I used one with 4x dual dp switching at home to run desktop with linux, pcie passthrough gaming vm on same machine and my work laptop via a dell thunderbolt dock connected to it.

Works extremely well, with modern features tested for (gsync, high refresh etc etc).

edit: one thing to note is that you need really good quality cables, so don't cheap out

I get how the Linux desktop and the Work Laptop would work in this setup.

But how does the KVM come into play for the Gaming VM when it is on the same host?

It was pci passthrough so the vm had a dedicated gpu, usb controller and nvme drive which I wired to the hardware KVM as extra inputs.

There are other options like https://looking-glass.io/ , but I preferred having this option, which is like having 2 computers if there's enough resources to share to the gaming guest (cpu pinning + huge pages).
