spice-vdagent-log
Hi Radek, Could you please clarify the step "1. Create new VM, add user and log-in. Do not log-out this user." on what you do exactly? If I try to switch user in GNOME interface, file transfer works as expected so I'm guessing you are doing something else. As the regression flag is set, it is also nice to know the prior version that this situation did not happen.

' "Do not log out this user" - I mean user account should not go through log-out procedure - ever (to reproduce this bug). Now I found that if I restart /usr/bin/spice-vdagent (instead of log-out + log-in), I cannot reproduce this. > If I try to switch user in GNOME interface, file transfer works as expected > so I'm guessing you are doing something else. > > As the regression flag is set, it is also nice to know the prior version > that this situation did not happen. I cannot reproduce this on rhel7.5 guest (kernel-3.10.0-862.el7, gdm-3.26.2.1-5.el7, dbus-1.10.24-7.el7). There is the same version of spice-vdagent (spice-vdagent-0.14.0-15.el7), so maybe the bug is elsewhere. Trying to reproduce. Talked with Radek, it is a bit tricky to get spice-vdagent logs as that would always imply rebooting or restarting the agent and bug would not be reproducible anymore. Downloading image where this happens. Situation that this issue happens seems very limited and easy workaround, removing the blocker flag. > journalctl -r -t spice-vdagent
> spice-vdagent[4058]: warning could not get file xfer save dir, file transfers will be disabled
So the file transfer was disabled in the agent because it could set a target directory for file transfers to be stored.
That's happening because g_get_user_special_dir () is returning NULL for either G_USER_DIRECTORY_DESKTOP or G_USER_DIRECTORY_DOWNLOAD.
That seems to be happening due a race between spice-vdagent and xdg-user-dirs as both can be started in parallel due .desktop settings being X-GNOME-Autostart-Phase=Initialization
Many thanks to Ray Strode on clarifying this :)

Create new VM, add user and log-in. Do not log-out this user. 2. Transfer some file from client to guest VM (drag'n'drop) Actual results: File is not transferred. Message 'An error caused the following file transfers to fail: $filename' appears. Expected results: File is transferred from client to guest Additional info: Files could be transferred if user is at least once logged-out (by restarting Vm, shutting it down, or simply user log-out) and then logged-in. If Vm is shutdown forcibly, and then (after VM boots up) is user logged-in, file transfer will not work.
