Fedora 34 guests can no longer paste from host

[Victor Toso]

Hi,

There is nothing obvious to pinpoint here. I can see that
spice-vdagent in Fedora is not using the gtk backend [0] but it is
hard to tell what is happening so far.
What version of spice-gtk you have?

Here the client notify some clipboard text to the guest. Not sure if
it was sent to the guest (the agent needs to request the data).

We need the agent's debug log as well. You need to create
/etc/sysconfig/spice-vdagentd and set SPICE_VDAGENTD_EXTRA_ARGS="-d"
for the system agent.
We should be able to see some messages like below or errors with:

journalctl -t spice-vdagentd spice-vdagent # (in the guest)

 | Apr 14 16:49:04 fedora spice-vdagentd[1086]: 0x5627c402dce0 sent

Cheers,
