Max, Today I changed my KDE host and guest VM to both use X11 and not Wayland.
(spice-vdagent is installed in VM) Cut/Paste clip board between host and guest did not work, in either direction. Very disappointing. XFCE supports Cut/Paste clip board between host and guest. I should give Cinnamon a try when I get the chance. I am hoping that in the longer term future, spice-vdagent will still be supported as I know no other way to get sound and video working to a network isolated VM. George.
