The log shows that you have the guest additions in the virtual CD/DVD drive. Now you just need to mount it and run the install from the guests terminal.

This should help Howto: Install Linux Guest Additions

3) mount /dev/sr0 /media/cdrom -- completed

4) sh ./VBoxLinuxAdditions.run -- While running this command,
The following error occurred:

bzip2: command not found

Looks like you do not have bzip installed. That would be the first place to start.

Hi,
I have installed bzip2 and installed the GA.
5) yum install bzip2

6) sh ./VBoxLinuxAdditions.run -- While running this command,

Please suggest.

Could not find the X.Org or Xfree86 Windows system.

Do you have a desktop installed? Xorg and some desktop is required. Other than that you are running in command line and the guest additions will not help there.

Hi
Thanks for the update.

Can you pls provide steps for - how to install Desktop?

Post the guests log file ( as an attachment ). Right click on the guest in the Main Manager then click show log. Save and post as an attachment. Compress if it is too large to post.

Hello Perry,

I have attached the logs.

Please suggest.

00:00:07.055897 Host path 'C:\Software_Dump\OracleSoftware', map name 'OracleSoftware', writable, automount=true, create_symlinks=false, missing=false

You have set your share to automount and this is what is causing you issues. Automount is a special mount that requires you to have your guest user name in the vboxsf group. As such it is mounted as a media device and not a normal users mount.

I would suggest that you remove the automount and then create a standard permanent mount instead. Follow the direction in the following post.
Linux guest shared folders

Hello Perry,

Thanks for the update.

As your suggestion, I have removed the old share-name and created new share-name as share1 with permanent mount option (checkbox clicked) and auto-mount - checkbox - UNCHECKed.

and then rebooted the Guest OS Oracle 7.1 and then entered the following command to mount the share folder.

and getting the same error.


[root@rac1 / ]# mount -t vboxsf share1 /mnt
/sbin/mount.vboxsf: mounting failed with the error: No such device

again tried...

[root@rac1 / ]# mount -t vboxsf share1 /media/share1
/sbin/mount.vboxsf: mounting failed with the error: No such device


and also attached the latest log. Please suggest.
