FEDORA21 installation VirtualBox

Loading Dkms,kernel-devel,makecache:

Yum install Dkmsyum install kernel-develyum makecache

Download VirtualBox https://www.virtualbox.org/wiki/Linux_Downloads and install:

Yum localinstall virtualbox-4.3-4.3. 8_92456_fedora18-1. x86_64.rpm-y

Installation is complete, creating the virtual machine and encountering an error when it starts:

 is  is a permission problem with/dev/vboxdrv. Reinstall the kernel module by executing'/etc/init.d/vboxdrv setup' as  is inch if necessary.

then compile VirtualBox kernel:

Trying to register the VirtualBox kernel modules using dkms[OK]

If the following error occurs, the kernel corresponding kernel headers or kernel version inconsistency is not found :

To view the kernel version:

To view the installed kernel version:

[Email protected] zhanghua]# RPM-QA|GREP headers
Kernel-headers-3.17.8-200.fc21.x86_64
Glibc-headers-2.20-7.fc21.x86_64

Yum Install kernel-headers-3.18.7-200.fc21.x86_64

The versions are identical after rebooting:

[Email protected] zhanghua]# uname-R3.18. 7-fc21.x86_64[[email protected]-zhanghua zhanghua]# rpm-qa| grep headerskernel-headers-3.18. 7-fc21.x86_64glibc-headers-2.20-7. fc21.x86_64

Compile again, the result is normal ( compile the VirtualBox kernel, if it fails , you may need to install dkms again ):
