Shared Folders on MX Linux

Post by EgonF »

I installed VirtualBox 6.1 on Windows 11 and created two VMs with a shared folder WinDok. But on both VMs I cannot find the shared folder.

In the log 10-36-31 I see

00:02:14.500072 SharedFolders host service: Adding host mapping
00:02:14.500104 Host path 'E:\WinDok', map name 'WinDok', writable, automount=true, automntpnt=, create_symlinks=false, missing=false

but I don't see /media/sf_WinDok.

After restarting the VM the log (11-57-10) has

00:00:03.146240 SharedFolders host service: Adding host mapping
00:00:03.146247 Host path 'E:\WinDok', map name 'WinDok', writable, automount=true, automntpnt=, create_symlinks=false, missing=false

but again there is no /media/sf_WinDok.

Have you added the 'user' to the vboxsf group in the MX VMs?

The Logs appear to be incomplete. Possibly taken before the VM was completely shut down?

However, the first log (HeraServer-2022-08-13-11-57-10) does show configuration issues:
00:00:16.098372 VMMDev: Guest Additions information report: Version 6.0.0 r127566 '6.0.0'
This is probably the version distributed with the MX Linux installer and is well out of date, so might well be the cause of the shared folder problem. I suggest you update the guest additions, using the 'current' version provided with the VirtualBox installation.

- After launching the VM use the VirtualBox Menu > Devices > Insert Guest Additions CD Image...
- Use the MX File Manager to select the CD drive and with its contents visible right click to launch Terminal
- In Terminal issue the command - sudo sh ./VBoxLinux Additions.run
- Watch for any error messages in terminal, but assuming all goes well on completion eject the 'CD' and reboot.
- Check that the user is listed as a member of the vbxxsf group; and then try to view the shared folder(s) again.

Also:
00:00:02.580656 NumCPUs <integer> = 0x0000000000000001 (1)
You may need to increase to 2 CPUs if there is any lag in performance.
00:00:02.580777 VRamSize <integer> = 0x0000000001000000 (16 777 216, 16 MB)
Is 16 MB Video RAM really likely to be sufficient for the VM screen sizes/resolution you will want to use? I would max the allocation to 128 MB when the VM is shut down.

Please let us know how you get on.

Hi,

I destroyed HeraServer and created a new VM. I installed MX Linux. After restart I wanted to add the GuestAdditions. I have got this error:

Das virtuelle optische Medium C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso konnte nicht in das Laufwerk der Maschine HeraServer eingelegt werden.



Could not mount the media/drive 'C:\Program Files\Oracle\VirtualBox\VBoxGuestAdditions.iso' (VERR_PDM_MEDIA_LOCKED).

Fehlercode: E_FAIL (0x80004005)
Komponente: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}
Callee: IMachine {85632c68-b5bb-4316-a900-5eb28d3413df}

I looked up Windows 11 Explorer. The file was blocked because the file is from another computer. I deblocked the file as an administrator. But after this I have got the above error.

The VERR_PDM_MEDIA_LOCKED error is common and can be web-searched. Basically, Linux likes to grab rrrreeeeaaaalllllllllyyy hard on its CD-ROMs, probably because they mount them to use them, and won't let the "CD drive" be opened. I'm not certain of the solution, but the web-search will provide the answer.

I could load the GuestAdditiions file and install the Additions.

Now SharedFolders work.

Thanks

Thanks for letting us know that you've solved the problem. I suspect that the Guest Additions ISO file was held by another VM and needed to be released before it could be re-used.

Hope everything is working now.
