REGRESSION: Shared folders randomly disappear and reappear from Windows guest

Reported by: matteosistisette Owned by:
Component: shared folders Version: VirtualBox 4.1.10
Keywords: Cc:
Guest type: Windows Host type: Linux


I have a Windows-guest VM with a shared folder configured. When I installed the guest OS I installed the guest additions and a network drive (E:) was created for the shared folder.

Every once in a while, I start the VM and the network drive corresponding to the shared folder is not there, it simply does not exist. The shared folder is accessible under
Vbocsrv but the network drive is gone.

The first time it happened, I re-added it manually in the guest as X: Then after some reboots of the guest, the original network drive E: magically reappeared, and I had both E: and X: both pointing to the same network folder.

This had never happened in VB 3.x this is a (yet another) regression in Virtual Box 4.

A VBox.log file of such a VM session is missing. Which Windows version is that? I've never seen such a problem with any Windows XP, Vista and Windows 7 guest, having a network drive mapped there since ages.

I wonder why I'm not getting email notifications of updates of bugs I've reported. I used to.

I'll attach all the logs but I have no idea which of them contain the sessions where the issue showed up. (mmmmm I always assumed VBox.log was always the latest and VBox.log.X were the older ones and that all logs were kept almost forever, but now looking at the file dates the oldest seems to be of two days ago so I'm not sure the relevant session is there at all..........)

The guest is windows 7 64bit; the host is Ubuntu 11.10

Happened again. Now I attach the logs of the session.

This happens about 50% of the times. May be it's every first time I start the VM after launching VirtualBox, and the issue goes away when I restart the VM.

Actually, this time even rebooting the VM didn't fix the issue, so it seems to be random.

The shared folder is visible in the guest as
vbox\xxxx but the network drive E: is gone (and it used to be there).

Please reopen if still relevant with a recent VirtualBox release.

Please reopen

The exactly same symptoms with Version 5.1.28 r117968 (Qt5.6.2)

Guest: Windows 7 64 bits

Many thanks
