I do not think there is a need for the reboot here. Just check the vbox* modules are installed under /lib and then run modprobe for each vbox module; make sure the vbox startup scripts at /etc/init.d/vbox* are all (re)started. To just check whether the VBoxAdditions are working, I would start with testing the copy-paste between the source and vmguest. Run VBoxClient-all command and see if it returns anything. If nothing is returned VBox is setup fine. Also, check chkconfig to make sure the vbox startup scripts are properly defined to start at required runlevels. – Nov 30 '11 at 10:24 •. @its_me's answer almost worked, but it failed building some kernel modules. If it doesn't work for you, look at the messages. In my case, one of them asked to look into /var/log/vboxadd-install.log. There it said something about missing kernel sources and to provide the kernel source directory with e.g. VirtualBox GuestAdditions for Linux Guest OS. “Devices -> Insert Guest Additions CD Image” Installing the GuestAdditions: su. This entry was posted in Concept and tagged CentOS, VirtualBox, VirtualBoxGuestAdditions on October 4, 2017 by Alexander Leonov. The guest additions are a set of device drivers (graphics and mouse drivers) and system applications that is going to be installed in the guest OS. One of them is a VirtualBox kernel module. This kernel module must be compiled in the guest OS. VirtualBox Guest Additions is a software package for VirtualBox that expands its abilities and provides a more seamless user experience. Adding Guest Additions is not required, but allows the VMs. Install Guest Additions via a Terminal. Login into terminal and run the following commands to mount the Guest Additions ISO file, move into the directory where the guest additions ISO has been mounted, inside there you will find VirtualBosx guest addition installers. $ sudo apt install build-essential dkms linux-headers-$(uname -r) 3. Next, from the Virtual Machine menu bar, go to Devices => click on Insert Guest Additions CD image as shown in the screenshot. This helps to mount the Guest Additions ISO file inside your virtual machine. 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/VBoxLinuxAdditions.run Now it complained about missing header files and suggested to do yum install kernel-devel-2.6.32-504.el6.x86_64 As you can see, this is a slightly different version, 504.16.2 vs just 504. After installing the proper kernel-devel package, building and then installing worked as expected. So, running kernel and installed kernel sources (aka kernel-devel) must match. You can verify this by looking at the running kernel with uname -a and the installed sources at ls /usr/src/kernels As a final conclusion, whatever happens, look at the messages and log files provided. Just a little detail. I had a CentOS 6.6 minimal, did all the 'yum update' and 'yum install' but I was still stuck until I've read this in Olaf's response. This is a slightly different version, 504.16.2 vs just 504. After installing the proper kernel-devel package, building and then installing worked as expected. So, running kernel and installed kernel sources (aka kernel-devel) must match. Checking on my install I had the same problem, after doing a reboot, everything was ok. The machine was still running with the old kernel. Star plus serial yeh rishta kya kehlata hai live. After this the next problem as that perl was missing so I had to do also an yum install perl. CentOS as a Guest OS in VirtualBox Installation of CentOS as a guest OS is much like installing on real hardware. Start by downloading the ISO file[s] you wish to use for installation from a. Creating a Virtual Machine Create a New Virtual Machine (VM) with the Virtual Machine Wizard, choosing Linux for the OS Type and Red Hat or Red Hat (64 bit) for the Operating System. Memory should be at least 768MB for a graphical install to work. Next the virtual hard disk wizard will start. The OS disk should be at least 8GB. For a relatively full install, allocate at least 15GB, otherwise use all the defaults. Additional disk[s] can be added later if desired. After the VM is created, run Settings, go to Storage, and under IDE Controller click on the CD icon on the left, then select the similar CD icon on the right and pick Choose a virtual CD/DVD from the list. Navigate to the directory where the ISO image[s] reside and pick one, for example CentOS-6.7-x86_64-LiveDVD.iso or CentOS-7-x86_64-DVD-1511.iso. Change any additional settings, such as the amount of memory for the virtual video adapter, and whether to use NAT or Bridged networking. For a first install attempt make a minimum of changes to the defaults. Start the VM and perform a graphical install, or if desired a text install. Screensavers the underwater world of shipwrecks and sharks schedule today. After the install reboot and perform firstboot configuration. Installing Guest Additions You will need to be the root user for the following tasks. Login to a root shell or 'su -' in a terminal window. The installation of VB will require the building of kernel modules. If DKMS (Dynamic Kernel Module Support) is installed it will be used and will simplify kernel upgrades. Installing DKMS from the repository is recommended before installing VirtualBox. Don't forget to configure the plugin. Installing DKMS may pull in required development dependencies, depending on the package source. Yum install dkms If DKMS is not used the Guest Additions will need to be reinstalled after every kernel update. If the development environment and kernel source are not already installed: yum groupinstall 'Development Tools' yum install kernel-devel You may also choose to only install a minimum set of individual development tool packages (at least gcc and make are required, in addition to kernel-devel) rather than the groupinstall which some may consider overkill. Replace 'kernel-devel' with 'kernel-PAE-devel' if using a PAE kernel on CentOS-5. If you are not using a standard CentOS kernel, you must acquire and install the source for your kernel from wherever you got the kernel. Do not try to install a Xen kernel in a Guest OS, or run KVM or any other nested virtualization hypervisor. From the VM Devices menu select Install Guest Additions. If running a GUI the virtual CD image for guest additions will automount - for instance under CentOS-6 with KDE it is mounted under /media/VBOXADDITIONS_5.0.14_105127. If autorun is enabled in a GUI you may get a window asking if you want to let the autorun execute, and asking for root authorization. Take all the defaults and the install should complete. If not in a GUI, or if there is no autorun, as root mount /dev/cdrom or /dev/sr0 (if necessary) and cd to the mountpoint. Type./VBoxLinuxAdditions.run to install. Patch for specific CentOS version Usually after a point release, which introduces major changes to the kernel or other subsystems, the compilation of the vBox tools fails. When such issues arise we will try to post applicable patches here, until this issue is fixed by vBox. This page created.
