Hello,
I recently switched from an Nvidia rtx2080ti to an AMD rx7900xtx, but now I have issues with the mouse and keyboard in KVM/virt-manager. If I start a Linux guest the guest mouse is invisible as long as I stay on the monitor with the vm on it, if I go to the second monitor (gentoo host) and go back to the vm the host mouse is displayed it's like the host mouse is on top of the guest mouse. And the other issue is I can't lock/unlock the keyboard to the guest with ctrl-l+ctrl-r what makes a window manager unusable in a vm, apart from these two issues everything works fine.
I found a couple forum threads that had the same problem as me, and they said to enable EvTouch USB Graphics Tablet in virt-manager or change the controller usb model from 3 to 2, but that is not working for me.
Both of this issues where not present with the nvidia card, the things I changed was obviously the gpu enabling the amdgpu kernel module based on the wiki https://wiki.gentoo.org/wiki/AMDGPU install the linux-firmware package and replace nvidias driver with mesa.
