Linux Additions should still be able to read network config without D-Bus

[AxelFontaine]

Currently lines 1472-1478 of /src/VBox/Additions/common/VBoxService/VBoxServiceVMInfo.cpp look like this:

rc = vgsvcVMInfoWriteUsers(); if (RT_FAILURE(rc))

break;

rc = vgsvcVMInfoWriteNetwork(); if (RT_FAILURE(rc))

break;

This unfortunately means that if vgsvcVMInfoWriteUsers() fails due to a missing system D-Bus, no network info is exposed as guest properties. There is no reason for this.

Suggestion: simply continue with vgsvcVMInfoWriteNetwork() even if vgsvcVMInfoWriteUsers() fails

This affects all currently supported VirtualBox versions.

You're right, the VM information / guest properties should continue to work, even in case some former enumeration part failed.

We're still interesting why this actually fails on your guest ...would you mind creating a verbose VBoxService log on your guest and attach that log to this defect then?

To start VBoxService in debug mode with verbose logging on a Linux guest (Debian-based, like Ubuntu etc):

Login as root, open a terminal window and do: # /etc/init.d/vboxadd-service stop Edit the file "/etc/init.d/vboxadd-service" by changing the line "daemon $binary > /dev/null" to "daemon $binary "-vvvv --logfile /var/log/VBoxService.log" > /dev/null" and save the file afterwards.

Then either the system needs to rebooted or VBoxService needs to be started again by doing a

# /etc/init.d/vboxadd-service start

This will start VBoxService in background, logging to /var/log/VBoxService.log. After the issue appeared again, please provide the logfile located in /var/log/VBoxService.log on the guest. Thanks!
