How to set up absolute mouse movement mode on KVM

Hello! I use virt-manager as frontend for KVM, and I'd like to set the mouse movement mode to "absolute", that should fix weird mouse problems in the VM for certains applications (games at most: minecraft mouse lock does not work with the default setting). If I go into the VM settings, under "Mouse", I get:

Virtual Input DeviceType: PS/2 MouseMode: Relative Movement

with no options to change these settings. This is the XML:

 xml

    
<input type="mouse" bus="ps2"/>

  

can I set this without editing XML? If not, how can I modify the XML to get this work?

thanks in advance!

EDIT: I solved by going in the VM settings > add hardware > input > USB mouse
