#18341 fixed VBoxManage showvminfo segfault in 6.0.x -> fixed in releases after 6.0.4 pentagonik gizero
Description

After upgrading to 6.0, already existing VMs that used USB passthrough (at least one filter enabled) stopped being controllable by vagrant. After quick inspection I noticed this is not an issue with vagrant itself, but a consequence of it running VBoxManage showvminfo behind the scenes for its own purposes.

Indeed the above command is segfault-ing systematically on my host. This happens after it prompts "Currently Attached USB Devices:". This seems consistent with the fact that I don't have any issue with VMs that are not configured for using USB passthrough. Adding the --machinereadable option has no effect.

While this is a problem with tools relying on VBoxManage showvminfo for their own VMs lifecycle management, on the hypervisor VirtualBox side of things the VMs are apparently starting correctly and the USB passthrough itself seems to be working if devices are connected after boot. Still VBoxManage showvminfo is segfault-ing at every run.

Currently verified on an Ubuntu 16.04.5 host with latest updates. Same happens with latest VirtualBox 6.0.2.

Here is the segfault context I have collected so far.

VBoxManage[3754]: segfault at 0 ip 000000000045cf0d sp 00007ffe37e1e550 error 4 in VBoxManage[400000+10a000]

Things I tried already, with no noticeable result:

  • upgraded to latest 6.0.2
  • created fresh machines with different (recent) guest OSs and USB passthrough enabled (all fail)
  • configured USB filters for a couple of different devices

Let me know if I can provide more context or how to proceed with further testing.

#18340 duplicate VirtualBox 6.0 Vlczech
Description

I have mounted some dirs from Windows 10 host to Linux in VirtualBox. Now in new version 6.0 (both 6.0.0 and 6.0.2), sometimes after re-running from saved state, these mounted shared folders are not accessible:

$ git checkout master
fatal: failed to stat '/home/someuser/<some shared folder>': Protocol error (original message suffix: "Chyba protokolu")
$ ls
ls: directory '.' could not be open: Operation not permitted/allowed"
(original message: "ls: adresář '.' nelze otevřít: Operace není povolena")

On the previous version 5.2.22 I didn't have the promblem with this.

#18338 duplicate VMM will not start Gemini
Description

Hello

I have just instaled VM box manager yesterday and already have a problem.

When I click on Start in VMM, it seems like it works. Unfortunately not.

I get this message:

Failed to load unit 'lsilogicscsi' (VERR_SSM_LOADED_TOO_LITTLE). Result Code: E_FAIL (0x80004005) Component: ConsoleWrap Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

As I am new to SAS, I would be grateful for the help.

Zrinka
