HELP!!

I just dont know what to do anymore..i have followed you instructions, installed ALL the necessary packages, updated yum, updated the whole system… I continue to get the same stupid error:

“echo ” ERROR: Kernel configuration is invalid.”; \
echo ” include/generated/autoconf.h or include/config/auto.conf are missing.”;\
echo ” Run ‘make oldconfig && make prepare’ on kernel src to fix it.”; \

What does this mean? Make oldconfig and make prepare? I tried to run these commands as root in the kernels directory and nothing happened. What am I supposed to do? Is Linux really that difficult to understand, or am I just doing things wrong?

Hi Help,

When do you get this error?
You seem to be missing something.

what does the logs say? /var/log/vboxadd-install.log

Below is a link to a similar issue and fix

Linux isnt hard.
It gives the user control of everything. So It takes patience to understand all the details.
Eventually you will feel that you can pretty much change anything on the system!

Hi RoadRunner: :)

Thanks for the reply. Sorry for my frustration, it was just that I really wanted to dive into Fedora and see what it had to offer. I did some research on virtualbox.org and found that the problem was caused by fedora kernel update (version 3.5) I repaired it by using the virtualbox guest editions 4.2 beta1 at http://download.virtualbox.org/virtualbox/4.2.0_BETA1/.

Since then everything is working fine, except for seamless mode.. Whenever I activate it, I only see the windows desktop but not the fedora taskbar, which should be located at the top of the screen. I find this most strange, since it works flawlessly with CentOS 6.3. Is there something in the setting that I need to activate in order to see the taskbar?

Sorry for my bad typing. It is very late here in Germany, and I am tired.. I meant to say that I fixed it using Virtualbox guest additions 4.2 beta1. There was a discussion over the problem here: https://forums.virtualbox.org/viewtopic.php?f=3&t=50748

I thought it best to describe the situation that I am having with seamless mode:

My guest OS is windows server 2008. When I activate seamless mode in Virtualbox the fedora desktop completely disappears, leaving only the Windows desktop and the Virtualbox taskbar on the bottom of the screen. The Fedora taskbar that should be located at the top of the screen is not visible. The only time I see anything from Fedora in seamless mode is when I have a window open. However when I close that window I am unable to use Fedora again until I switch to a different mode (fullscreen for example).

My question is if there is something in the settings that I must change, or is there anything extra that I must download in order to get Fedora fully integrated in seamless mode? Thanks for the response. :)

JR,

First off. Thank you for all your tutorials. I wish there was a way to pay your or compensate you, maybe just recommending your site to friends. But, please, accept my many thanks!

New to linux, have used many of ur tutorials. This one made me stuck.

My problem is from the beginning.
When I input: mount -r /dev/cdrom /media/VirtualBoxGuestAdditions
Sys output: mount: no medium found on /dev/sr0

From here, I follow instructions to finish w/out visible errors until the end.
I input: ./VBoxLinuxAdditions.run
Sys output: -bash: ./VBoxLinuxAdditions.run: No such file or directory

I don’t know what I am doing wrong, all kernel updates say:
no packages marked for update or already installed and latest version

please help (at your earliest convenience of course!) :)

Hi Zosimo,

What happens when you click “Install Guest Additions…”?

Does it mount automatically Virtual Box guest additions on your system?

Hello,
I have spent the better part of my night trying to install the Virtual Box Guest additions
My issue was that the install could not find any flies related to kernels under /usr/src/kernels.
The folder showed as empty.
The issue was I could not view the files in that folder when logged in to the root account…
When I logged out and logged back in as “user” then I could view the files and install Virtual Bx guest with no issues…..
I hope this save someone some time!
Can any one tell me why I could not view the files in /usr/src/kernels logged in as root?

Hi Net@this,

This sounds interesting, could you post output of following command as normal user and root user:


ls -la /usr/src/kernels

Could you also post output of following commmand:


rpm -qa kernel\* |sort
