Startup - Fatal Error "Failed to initialize VB COM Server"

[mbarrene]

Hello,

I am currently running Mac OS X Snow Leopard on my Macbook Pro, and just yesterday I installed VirtualBox 3.0.6 for a virtualization class I am taking.

I'm having a bit of trouble starting it up after downloading the .dmg file and installing VB on my computer. The error reads:

" Failed to initialize COM or to find the VirtualBox COM server. Most likely, the VirtualBox server is not running or failed to start.
The application will now terminate.

Callee RC:
NS_ERROR_FAILURE (0x80004005) "

Any help with this is issue would be great. I haven't found any substantial support on the forums for this problem, so I was wondering if somebody could help me out here.

Thanks,
Mario

Did you add your user name to the vboxusers group?

[mbarrene]

No, I haven't done that. I'm not too familiar with VB, but I can't get it to start up because of the error.

How do I put my username in the vboxusers group?

Not really sure about MAC but in Linux the command below works: I do know the error you are getting is exactly what you get if you are not in the vboxusers group though.
In terminal as SU

Code: Select all

usermod -aG vboxusers <your username>

No luck with the usermod command. I searched through my Unix Executable Files and don't recognize any commands labeled "vboxusers". The only command I do know that just runs the VB app is "Virtualbox".

*Bump on this thread. Does anybody know how to add my username to the "vboxusers" group so I can resolve this "VirtualBox COM Server" problem I am still having?

Thanks!

I have the same problem on my MacBook (Mac OS X Leopard). What do you mean about the group? I have added my user to the virtualbox app, but this doesn't solve the problem. What can I do to solve it?
