Open an command line prompt as Administrator and execute:.Create the directory "C:\Temp" on the guest if it does not exist yet.The resulting logfile in "/tmp/VBoxClient.log" on the guest drop issue should now contain a lot more logging statements beginning with Save the file /etc/X11/Xsession.d/98vboxadd-xclient.Do the same editing as above with the file /etc/X11/Xsession.d/98vboxadd-xclient.VBOX_RELEASE_LOG_DEST="file=/tmp/VBoxClient.log" VBOX_RELEASE_LOG_FLAGS="time tid thread" VBOX_RELEASE_LOG="all.e.l.l2.l3.f" /usr/bin/VBoxClient -draganddrop As root, open the file /usr/bin/VBoxClient-all and change the line.Make sure you at least have the VirtualBox Guest Additions 5.0 or higher installed.For that also system-wide environment variables need to be set on the guest (not on the host!).įor Linux, BSD or Solaris guests, do the following: For that to diagnose please read the next section.Ĭollecting drag and drop debug information on the guest is similar to collecting it on the host. Sometimes, however, the error does not occur on the host but on the running guest itself. This is all what it takes to gather drag and drop debug information from the host. The resulting VBox.log of the VM you reproduced the drag and drop issue should now contain a lot more logging statements beginning with Perform and reproduce the faulty drag and drop operation (from host to guest or guest to host).Start the VirtualBox Manager and start the VM you want to diagnose drag and drop for.
On POSIX-enabled systems like Linux, Unix or OS X you can add the following to file /etc/profile:Įxport VBOX_RELEASE_LOG=guest_dnd.e.l.l2.l3.f On an Administrator command prompt to set this on a system-wide level (required). Setx VBOX_RELEASE_LOG "guest_dnd.e.l.l2.l3.f" /M Set (see the description of the logging facility for more background).
Second note: The guest needs to have the VirtualBox Guest Additions installed in order to perform drag and drop operations from/to the host. Older versions of VirtualBox only had experimental support and therefore are not supported. The adjustments affect the host operating system as well as the guest you want to use for this drag and drop operation.įirst note: Drag and drop support only is available for VirtualBox 5.0 and newer. To diagnose your problem further we need you to run your VirtualBox installation with several adjustments being made. Handling drag and drop operations across various host and guest OS combinations is a difficult and time sensitive topic. Investigating drag and drop (DnD) problems
