> 3.restart remote-viewer

You mean that you Quit and launch it again or you did something else?

> file transfer is suck with copy.

Could you attach the logs from the agent? Would be great if you could do a small copy that works and than the big one, from steps 2, 3 and 4 just to
show that it was working and that it breaks when you quit. Probably some bad state in the agent.

> Copy dialog window is open and cannot be closed. Progress bar stays at zero position.

Errg. That's a bug in the client. Could you please also open a bug there?

Hi Victor,
yes in step 3 I quit remote-viewer and launch it again.

a) successfully copied to guest:

b) unsuccessfully copied to guest -> interrupted (by remote-viewer restart)

Yes you are right spice-vdagent is somewhat stuck - display resize does not work after remote-viewer reconnection. It works again after spice-vdagent service is restarted.

Comment 3 Radek Duda 2019-02-27 10:49:45 UTC
I forgot to mention that after spice-vdagent service is restarted (after step 4), an error message-box appears : 'An error caused the following file transfers to fail: $filename'. Maybe it can help to identify in what situation has vdagent stuck.

Yep, bug in the agent, should be fixed asap.
Workaround is restarting the agent, either by restarting the vdservice, logout/login or rebooting VM.

Thanks!
