You can verify this by looking at the running kernel with uname -aДЄnd the installed sources at ls /usr/src/kernelsДЄs a final conclusion, whatever happens, look at the messages and log files provided. So, running kernel and installed kernel sources (aka kernel-devel) must match. Next, use Virtualbox to download the Guest Additions, then select 'Install Guest Additions' from the Virtualbox menu.

Making use of these facilities, VirtualBox can run each guest VM in its own separate address-space the guest OS ring 0 code runs on the host at ring 0 in VMX non-root mode rather than in ring 1.

After installing the proper kernel-devel package, building and then installing worked as expected. VirtualBox supports both Intels VT-x and AMDs AMD-V hardware-assisted virtualization. To make use of the shared folders feature that is built into VirtualBox you need to install the VirtualBox guest additions in the guest operating system. Now it complained about missing header files and suggested to do yum install kernel-devel-2.6.86_64ДЄs you can see, this is a slightly different version, 504.16.2 vs just 504. Since kernel-devel and sources at /usr/src/kernels/2.6.32-504.16.2.el6.x86_64 were already installed, I was confused, but called it with the requested environment variable KERN_DIR=/usr/src/kernels/2.6.32-504.16.2.el6.x86_64 sh /media/cdrom/n There it said something about missing kernel sources and to provide the kernel source directory with e.g. In my case, one of them asked to look into /var/log/vboxadd-install.log.

Building kernel modules requires certain software packages. When installing the VirtualBox guest additions, these kernel modules are automatically built, specifically for the kernel version currently running in Ubuntu. If it doesn't work for you, look at the messages. The VirtualBox guest additions for Linux consist of a bunch of Linux kernel modules. scottgus1 Site Moderator Posts: 13296 Joined: 30.Answer almost worked, but it failed building some kernel modules. And use the ISO that came with Virtualbox t o install the GAs. your Operating System on your PC and the FreeDOS guest In theory you could use virtual floppies or burn virtual CDs. So how do we exchange files between your host i.e. Then power off your Ubuntu guest OS to change some settings from VirtualBox manager as explained in the next step. Once the installation is complete, press Enter to close the installer terminal window. That means shared folders are not available for any DOS guests. A terminal window will be opened from which the actual installation of VirtualBox Guest Additions will be performed. But having the GAs be ahead of the main VB, that could go pear-shaped soon.ДЄs an example, when the GAs were causing shared folder issues recently, the devs didn't put out just new GAs, they put out a whole test-build of the entire Virtualbox program, GAs included.Дon't allow installing of new GAs without installing the matching version of Virtualbox. VirtualBox has no guest additions for DOS. Allowing the GAs to fall behind the main VB version isn't bad for a while.

As the developers update capabilities they put these capabilities in both the main Virtualbox and the GAs ISO. Software that has to work with partner software has to know what the partner is doing. It is not good to go downloading GAs besides the version that comes with the Virtualbox installer.
