virtualbox.org

Hi all,
I'm new to VM's and Linux, but trying my best to learn. I've googled and still no luck.

I'm running windows 7, virtualbox 4.3.28, CentOX 6.6 (I think these are the basics).

When starting up VM/Linux I get the message Kernel Service is Not Running. When googling around it said to delete vboxclient.desktop file from /etc/xdg/autostart. Then I restart and still I get the message.

I'm also having trouble setting up my shared folder. I got an error when installing Guest Additions: Building the main Guest Additions module [FAILED]. Not sure if these two issues are related or not.

Any help would be great.
Thank you!

Moved to "Linux Guests" forum, since I doubt that your Windows Host is relevant to the question asked.

Post the guests log file ( as an attachment )

Also if you can explain this a little better. You say it will not boot and then you say you are having problems installing the guest additions, which means the guest would have to be running.

1. Everything boots up. I"m able to get into CentOs and even connect to the internet. I see the error message in the attached screenshot when logging in though. Is it an issue or do I just need to get used to seeing it every time I start up?

2. I can't seem to share files between my host and guest. I've set up the shared folders correctly. I've tried installing the guest additions and I get the build error (attached screenshot).

I've also attached the log file.

Regarding your error. Did you read and do what was suggested in the printed reason for the failure?

yes, I believe I did. I can try it again.

yes, confirmed. I've restarted everything and still I get the same error message.

So if you install the guest additions again do you still get the message of missing kernel-devel?

Yes. I'm confused. Is the kernel issue and failure to build guest additions related?

Then you need to install them just like the message says.
But to eliminate any further issue use the following with elevated permission. SU/SUDO Then install the guest additions again and see if the error goes away and the additions are successful.

It works! I've run a similar command before but not sure why it didn't work before. Thanks for your help!
