Description Nikolay Kichukov 2021-05-31 09:15:17 UTC
If you emerge virt-manager on a system that does not run an Xorg server and virt-manager is started via x11 ssh forwarding, you may end up with a configuration where no setting changes can be saved.

It turns out that virt-manager requires dconf to write its configuration changes, however if dbus is not compiled with the X use flag, writing the configuration fails with an error:

failed to commit changes to dconf: Error spawning command line “dbus-launch --autolaunch=<some_id> --binary-syntax --close-stderr"

in ~/.cache/virt-manager/virt-manager.log

app-emulation/virt-manager[gtk] does not have a direct runtime dependency of dbus, however the dependency is inherited from: gnome-base/dconf, which does not seem to ask for X on sys-apps/dbus:

RDEPEND="
        >=dev-libs/glib-2.44.0:2
        sys-apps/dbus
"


Reproducible: Always

Steps to Reproduce:
1. Compile current stable app-emulation/virt-manager[gtk] on a system where there is no global X use flag
2. Launch virt-manager via an ssh tunnel with X11 forwarding from another system that runs Xorg server
3. Try to add a connection or make any changes via the UI, observe how they are not saved
Actual Results:  
The settings of the application are not saved

Expected Results:  
The settings of the application to be saved
