Here we can see that the QEMU guest agent started fine, but the SPICE
guest agent failed to start.

The SPICE guest agent is the one that provides clipboard integration.

Given that we see QEMU agent running, this smells like a guest OS
problem rather than a host problem.

Check whether 'spice-vdagent' is installed, and whether 'spice-vdagent'
and 'spice-vdagentd' are both running in the guest
