#8002 duplicate multiple virtual interfaces crash everything deever
Description

I have a VM defined with two virtual interfaces, one bridged to the host's eth0 and the other bridged to a bridge on the (linux) host:

eth0 (host) <- bridged mode <- VM (OpenBSD) -> bridged mode -> myvirtnet (bridge on the host)

As soon as i setup the virtual interface to myvirtnet, the host panics:

[ 1018.673596] Kernel panic - not syncing: Aiee, killing interrupt handler!

I'm not a developer, but for me it looks like the NULL ptr reference seems be the problem. I obviously can't provide a VBox.log since even for getting this stack trace I've had to use netconsole.

#3696 fixed multiple vboxtray.exe on WTS crash system Michael Kromer
Description

On a W2K3 WTS (Terminal Services) System, when logging in from remote, system crashes ("Aborted") when VBoxTray.exe is already running in console.

Problem is always reproducible.

Temporaily (workaround):

Remove vboxtray.exe from HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run and start it manually in the vbox window.

After this, system doesn't crash anymore.

Maybe there is no "already running" check in VBoxTray.exe?

#8177 obsolete multiple host user result in usb device driver not respond to plugin/out moo
Description

it's windows 7 here. i run everything below under administrator permission, either with administrator account or with UAC administrators permission

  1. login to "administrator" account, starts virtualbox, boot Gentoo linux

result: check procexp, i see process tree as service.exe -> svchost.exe -> VBoxSVC.exe (as Administrator account) (this is expected) result: plug in/out usb mouse or other device, it's fine

  1. switch to 'moo' account, start virtualbox with UAC administrators permission, don't boot any guest

result: check procexp, i see process tree as service.exe -> svchost.exe -> VBoxSVC.exe (as Administrator account), and VBoxSVC.exe (as moo account) result: plug in/out usb mouse or other device, it's fine

  1. close the one started by 'moo' account

result: check procexp, i see process tree as service.exe -> svchost.exe -> VBoxSVC.exe (as Administrator account), and VBoxSVC.exe (as moo account) hang around for a few seconds (this is expected)

all the result above is fine, expected. but here goes the problem

  • unexpected result: after a few seconds, "VBoxSVC.exe (as moo account)" is still there. it's expected to be terminated automatically
  • unexpected result: plug in/out usb mouse or other device, it's not detecting the plug in/out, the usb device(s) driver is keeping its old state before the bug happened, it's either in plugged or unplugged state by checking device manager in control panel

by stopping all virtualbox guest, usb device(s) become fine, VBoxSVC started by administrator is closed, but unexpectedly VBoxSVC started by moo account is still there, i can not kill it even with procexp

btw, i have vbox 4.0.2 installed correctly, extension pack is upgraded to 4.0.2
