I have installed a OpenSuse Leap 15 (KDE desktop enviroment) as guest on opensuse 42.1 host notebook with kvm as Hypervisor.
After the clean installation, (the first boot) the mouse work until login screen… after login the mouse pointer disappear and the mouse not work, i can interact only with keyboard.
I have tried:
run the update suggest and reboot (KO)
Reinstall the guest machine (KO)
Reinstall the guest machine with gnome (hang to leap logo after installation then the first boot) so i can’t verify the mouse functions
Go in init level 3 and try the basic cut and past command with mouse curson (KO)
The mouse kernel module (is bulit-in in the kernel) so i can’t reloaded

The problem is on the guest, openSUSE Leap 15, where the mouse pointer not appear and works only the keyboard, in fact when i press CTRL - ALT the mouse pointer appear but it’s on the host, openSUSE Leap 42.1 where it works as usual.
I am not having that problem here. For comparison, I’m running KVM under Leap 15.0. I previously ran it under Leap 42.3, and also did not have a problem. And I usually run Plasma 5, sometimes as a Wayland session and sometimes as an X session. I also just tested with Gnome, both X and Wayland, and did not see any similar problem.

That’s with Leap 15.0 also as the KVM host.
My mouse is actually a USB mouse. So that tells me that the guest machine is seeing a virtualized mouse (that’s not surprising). It suggests to me that your KVM host is not properly communicating with the Leap 15.0 guest. And I think that points to the problem that your 42.1 is well beyond its supported life. There have probably been some changes since 42.1 that Leap 15.0 as guest depends on.
