If would be helpful if you showed the XML config file for your guests, so we can
see what hardware you've configured. Hardware choices can make a big
difference to guest performance.

I'd suggest that you want to install the QXL video driver, and setup SPICE instead of VNC, along with the SPICE guest agent. This gives a much better performing graphics layer, and better performing mouse. instead of the USB tablet which is known to have high CPU cost.

USB tablet is a great problem too for a generated additional workload in idle, though usb3 tablet connection results in much lower cpu consumption than usb2.
