Use launchd daemon (or launchd agent) instead of deprecated StartupItem for VirtualBox on MacOSX => Fixed in SVN

[sierkb]

VirtualBox on MacOSX uses Startup Items (/Library/StartupItems/) and places files in /Library/StartupItems/VirtualBox .

Startup Items are deprecated since MacOSX 10.4 (and only recommended/allowed for legacy use) in favor of launchd daemons -- even more on MacOSX 10.5 and 10.6 and the forthcoming MacOSX 10.7.

See:

Apple Developer: MacOSX Reference Library: Technical Note TN2083: Daemons and Agents ​http://developer.apple.com/library/mac/#technotes/tn2005/tn2083.html

Section "Old Systems and Technology" -> Deprecated Daemonomicon ​http://developer.apple.com/library/mac/#technotes/tn2005/tn2083.html#SECOLDDAEMONOMICON

Suggested fix: Don't use a startup item placed in the (deprecated) directory /Library/StartupItems/ .

Instead, use a launchd daemon with a Property List placed in /Library/LaunchDaemons/ or a launchd agent with a Property List placed in /Library/LaunchAgents .

With major changes apparently coming for Mac OS X 10.7, this relatively simple fix should be given priority.

Any progress in this issue?

Any progress in this issue? Any estimated time of being fixed in the foreseeable future?

+1 to this issue.

The problem I face because of this is that I want to run a headless VM (using VBoxheadless) and this fails since the headless vm is started by launchd which requires (but cannot specify any dependencies on) the VB kexts to be loaded.

The VBox kexts are loaded after the vboxheadless startup has already failed.

StartupItems no longer exist in Mac OS 10.9 Mavericks. StartupItems was deprecated 8 years ago. Host-only adapters (and possibly other functionality) cannot be used in Mac OS 10.9.

Temporary work around: sudo /Library/StartupItems/VirtualBox/VirtualBox start (Must be run after each restart)

[Frank Mehnert]

Thank you for this information!

[Klaus Espenlaub]

For some reason (just as a data point, not as a justification to delay the switching much further) it seems that (limited) support for StartupItems was visible in the latest DPs, but it is failing in strange ways.

[ouster]

On Mavericks the above method does not work for me, however reinstalling Virtual Box on every reboot does. I consider this a major problem with Virtual Box on OS X Mavericks and should be given high priority.

[Keri Henare]

Before you can sudo /Library/StartupItems/VirtualBox/VirtualBox start you have to sudo /Library/StartupItems/VirtualBox/VirtualBox stop as it will have been partially started on restart.

[Frank Mehnert]

Will be finally fixed in the next major release.

[Frank Mehnert]

Fixed in VBox 4.3.

[ion]

The problem still appears with VirtualBox 4.3 on Mavericks (10.9), official release. Reinstalling VirtualBox 4.3 after each reboot solves the problem.

I took the following steps:

• I was using 4.2.18 before upgraded Mavericks, on Mountain Lion (10.8)
• I upgraded to Mavericks, I noticed the issue
• Found out that a 4.3 version of VirtualBox existed, installed it
• problem fixed
• after the first reboot, the problem appeared again
• reinstalling VirtualBox fixes the issue (the VMs can be started) until the next reboot

I installed Mavericks as a guest on a Mavericks host running VB 4.3. During the first boot of the guest, the out-of-box routine kept looping if I tried to manually configure the network settings so I eventually answered 'this computer doesn't connect to a network' (or similar wording). Once I was logged in to the guest, opening OS X's "System Preferences | Network" showed no Ethernet interfaces (nor could I add any by clicking "+"). I think I tried changing the VB guest's "Settings | Network | Adapter 1 | Attached to:" to "NAT" and started the guest but I still saw no Ethernet interfaces in OS X's "System Preferences | Network" nor could I add any, so I shut down the guest. To cut to the chase, I found this project

​https://github.com/pmj/virtio-net-osx

downloaded Virtio-net Driver 0.9.2.pkg to my Mavericks host from

​https://github.com/pmj/virtio-net-osx/blob/master/bin/Virtio-net%20Driver%200.9.2.pkg

and copied the .pkg file to and external USB drive. Then I started the Mavericks guest, copied the .pkg file to the guest from the external USB drive, installed the .pkg file, and manually configured the network settings. I shut down the guest and changed "Adapter 1 | Attached to: " to "Bridged Adapter" and "Adapter 1 | Adapter Type:" to "Paravirtualized Network (virtio-net)", restarted the guest, and now have a functional connection. These notes are taken from memory after spending a number of hours trying to install Mavericks as a fresh install on a new VM - wish I could say with absolute certainty that the sequence of events was exactly as written but it's the best I can do.

I had the same problem. Would work on first install but would fail after reboot. Re-installing made it work again.

I think the upgrade installer just has a bug. I read:

​http://jarneil.wordpress.com/2013/10/24/vritualbox-4-30-on-os-x-10-9-mavericks/

Long story short:

(1) sudo rm -rf /Library/Extensions/VBox*

(2) re-install vbox 4.3.0

Confirmed the workaround suggested by rwstandridge. I'm reopening the ticket in order to draw the attention to the installer issue that leaves the old version of the driver in /Library/Extensions, apparently causing the issue.

Apologies if reopening it is the incorrect course of action for this matter.

I can confirm that this workaround also worked for me:

1) sudo rm -rf /Library/Extensions/VBox*

2) re-install VirtualBox 4.3

ion above suggested needing to re-install after each reboot, but I have not found that to be necessary.

[ion]

Just to make things clear: reinstall after reboot was needed *before* removing the old, 4.2.18, extensions ("sudo rm -rf /Library/Extensions/VBox*"). After removal, everything worked fine.

The problem with the installer leaving the old kernel extensions at the old place was fixed in 4.3.2. Closing.

Thanks! I hope I was some small help!

Hi,

Even after doing the following:

1) sudo rm -rf /Library/Extensions/VBox*

2) re-install VirtualBox 4.3

Plus running the following:

sudo launchctl load /Library/LaunchDaemons/org.virtualbox.startup.plist

I still got errors:

Command: ["hostonlyif", "create"]

Failed to create the host-only network interface. VBoxNetAdpCtl: Error while adding new interface: failed to open /dev/vboxnetctl: No such file or directory

(Same case even adding manually through UI)

VirtualBox 4.3.2 vagrant-berkshelf (1.3.4) vagrant-cachier (0.5.0) vagrant-omnibus (1.1.2) Vagrant 1.3.5 Berkshelf (2.0.10) OS X 10.9 (Mavericks)

Thanks.

[galitsyn]

Could you please attach kextstat output and /var/log/system.log file?

Also, could you please check if running sudo /Library/Application\ Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh restart resolves the issue for you?

As for sudo /Library/Application\ Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh restart

Unloading VBoxDrv.kex
(kernel) Can't remove kext org.virtualbox.kext.VBoxDrv; services failed to terminate - 0xe00002c7.
Failed to unload org.virtualbox.kext.VBoxDrv - (iokit/common) unsupported function.
Error: Failed to unload VBoxDrv.kext
Fatal error: VirtualBox

[galitsyn]

It looks very likely that you have VBox process(es) running while attempting to unload VBoxDrv.kext.

Please check ps -Af | grep -i vbox output and if there are some processes just do pkill -9 VBox. Then re-do sudo /Library/Application\ Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh restart.

[hanxue]

Following this issue - affecting Vagrant on OS X Mavericks ​https://github.com/mitchellh/vagrant/issues/1671

[johnross.j.c]

sudo /Library/Application\ Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh restart

fixed it after machine reboot. It has to do with locked VBox kext.

[konrad]

I do have a problem which results in the same but is caused by a crash during startup. I attach several crash dumps here. The crash during the start of the machine causes the kernel drivers not to be available. A complete uninstallation and reinstallation of 4.3.10 did not fix the issue. I use Mac OS X 10.9.2.

Crash during start of 4.3.10

This crash does not happen when I try to start a virtual machine, but rather when booting my computer. I assume that somehow the VirtualBox is started during the start process of the host machine (to load some kernel drivers or something else). This fails and therefore the kernel drivers are not available. Which log file can I attach to help you identify the issue?

VirtualBox app do not start within /Library/Application Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh script which is used by /Library/LaunchDaemons/org.virtualbox.startup.plist in order to load kernel extensions on system boot. I presume that OS X attempts to relaunch the app on startup because it was running before you reboot (therefore, I think the issue you are observing is not related to this topic directly).

Probably, VM selector is crashing. In this case might make sense to upload /Users/<user>/Library/VirtualBox/selectorwindow.log file. Also, could you please specify VBox revision number in order to make me able to match crash report with the code (r93012 looks like not the revision you are running).

[konrad]

You are right, Mac tried to restart Virtualbox because it was started before. When Virtualbox was not running during the shutdown I no longer get the crash during start, but still the kernel drivers are not loaded. I attached the VBoxSVC.log. What can I check to make sure the kernel drivers are installed and loaded correctly? Manually executing sudo /Library/Application\ Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh restart. does the trick, but I would assume, that the installer should register that script to be executed at each machine start. What is wrong there?

[galitsyn]

Replying to konrad:

Firsts of all, could you please confirm that the crash report you attached corresponds to r93733 (revision from VBoxSVC.log)?

What can I check to make sure the kernel drivers are installed and loaded correctly? I would assume, that the installer should register that script to be executed at each machine start. What is wrong there?

Installer puts a .plist file into

/Library/Application Support/VirtualBox/LaunchDaemons/org.virtualbox.startup.plist

and a symlink to it into

/Library/LaunchDaemons/org.virtualbox.startup.plist

which in turn tells to launchd to execute

/Library/Application Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh

on a system start. Could you please confirm if org.virtualbox.startup.plist and its symlink are in place?

It is also might make sense to look into /var/log/system.log. Could you please attach it?

[konrad]

Some more observations: The plist is correctly symlinked

lrwxr-xr-x 1 root wheel 76 May 21 16:51 org.virtualbox.startup.plist -> ../Application Support/VirtualBox/LaunchDaemons/org.virtualbox.startup.plist

There is no crash file during startup nor a VBoxSVC.log when VirtualBox is not running during shutdown. To me it just seems that the VirtualBoxStartup.sh is just not triggered. Do you have any idea why? Triggering it manually does work.

[galitsyn]

Do you have any idea why?

/var/log/system.log might help to find the answer to this question.

I understand there is no crash currently, but still need the revision number in order to prevent such crashes in future.

[konrad]

It is saying: May 23 16:23:42 Konrads-MBP-Netcentric com.apple.launchd[1] (org.virtualbox.startup[85]): Exited with code: 1 Also I attached a new crash file (when trying to start a VM when the kernel drivers have not been loaded), which refers to VirtualBox 4.3.12 r93733.

[konrad]

New Crash of VirtualBox 4.3.12

[galitsyn]

Could you please replace

/Library/Application Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh

with the file attached below and submit launchd error from /var/log/system.log again?

[galitsyn]

Instrumented startup script

[konrad]

It just says:

May 27 11:19:37 Konrads-MBP-Netcentric com.apple.launchd[1] (org.virtualbox.startup[85]): Job failed to exec(3) for weird reason: 13

Do you have any other suggestions?

[konrad]

Both the /Library/LaunchDaemons/org.virtualbox.startup.plist and /Application Support/VirtualBox/LaunchDaemons/org.virtualbox.startup.plist have the execution flag set for all users (user, group, other)

[konrad]

And this is the output of ls -l in /Applications/VirtualBox.app/Contents/MacOS

Replying to konrad:

It just says:

May 27 11:19:37 Konrads-MBP-Netcentric com.apple.launchd[1] (org.virtualbox.startup[85]): Job failed to exec(3) for weird reason: 13

Do you have any other suggestions?

There seems to be a problem with VBoxUSB.kext loading. Does /var/log/system.log contain any related message?

[konrad]

Unfortunately not. The line before and afterwards are not related to virtualbox and looking for "virtualbox" and "VBoxUSB" did no lead to any results. The error 13 always has something to do with access rights (​http://superuser.com/questions/478768/running-app-on-macosx-mountain-lion-job-failed-to-exec3-for-weird-reason-13). Which file exactly is executed there? Do you want me to check some more execute flags?

I was wrong. The error 13 was indeed due to missing execute rights on the VirtualBoxStartup.sh (I must have done something wrong previously). Now (after fixing the execute rights) even with the instrumented startup script I get the following output

May 27 14:12:09 Konrads-MBP-Netcentric com.apple.launchd[1] (org.virtualbox.startup[92]): Exited with code: 1

Nothing else.

[galitsyn]

Could you please try the next instrumented VirtualBoxStartup.sh and check system.log again and attach /tmp/vboxdebug.txt file?

[galitsyn]

Extra instrumentation for startup script.

[konrad]

Thanks a lot. Now it says

Jun  2 19:54:42 Konrads-MBP-Netcentric com.apple.launchd[1] (org.virtualbox.startup[91]): Exited with code: 15

And vboxdebug.txt contains

Don't know why that is. The list view on /Library/Application Support/VirtualBox/ shows

[galitsyn]

If VBoxDrv.kext was failed to load, there should be a corresponding message in system.log. Could you please spot and attach it? Btw, in order to speed up the solution of the issue you are facing It is really might make sense to attach entire system.log.

[konrad]

Attached is the complete system.log of a computer restart. The only line referring to Virtualbox is the one I pasted above. vboxdebug.txt is the same as written above.

[aeichner]

Please reopen if still relevant with a recent VirtualBox release.
