How to align gpm mouse cursor with graphical mouse cursor in spice viewer (QEMU VM)?

I have a Linux console running in a virtual machine (QEMU/KVM). Inside the VM I use GPM in order to select and paste text with the mouse. However, when I enter the VM's spice virt-viewer window in my graphical desktop the graphical mouse cursor of the desktop is completely at a different position than the GPM mouse cursor. That is annoying and it means that some areas of the VM's text window cannot be reached without entering and exiting the spice window several times. **How do I align/synchronise the mouse cursors of spice/desktop and GPM?** I cannot install an additional program in the VM because it is a server. It must work with GPM alone. Perhaps QEMU needs some config options?
