install The Oracle VM VirtualBox kernel module needs a device node to operate. The above make command will tell you how to create the device node, depending on your Linux system. The procedure is slightly Linux kernel sources are used for the build process. Note that the /dev/vboxdrv kernel module device node must be owned by root:root and must be read/writable only for the user. Next, you install the system already been installed into your zone, you need to give the zone access to Oracle VM VirtualBox’s device node. This is done by performing the following steps. Start a root terminal and run the following command:
