virtualbox arch failed to load kernal modules

First copy your module to /lib/modules/$(uname -r)/kernel/drivers. This file should contain the names of kernel modules that are to be loaded at boot time, one per line. File /etc/modules use to load kernel boot time. Note you can see message on screen if you are logged in as root under run level 3.ħ) Verify that module loaded using the lsmod command:Ĩ) See message in /var/log/message file using the tail command or less command:ĩ) Unload the module using the rmmod command:ġ0) Load module when Linux system comes up. Make -C /lib/modules/$(KVERSION)/build M=$(PWD) cleanĦ) Become a root user (use su or sudo) and load the module: Create new Makefile as follows:Īppend following make commands: obj-m = hello.o This is an example modified from original source for demonstration purpose.ģ) Save the file. Printk(KERN_INFO 'Loading hello module. ') You need to be root user or privileged user to run insmod/modprobe:ġ) hello.c – It is C source code. Once module compiled successfully, load it using the insmod command or modprobe command. You can see all actual compile command stored in.

It will finally creates the foo.ko module in current directory. In other words, module build can be done by any user (no root level access needed): Make -C /lib/modules/$(KVERSION)/build M=$(PWD) clean Step 3 – Compile Linux kernel module Make -C /lib/modules/$(KVERSION)/build M=$(PWD) modules Next go to your kernel module source code directory and simply create the Makefile file as follows (assuming your kernel module name is foo):Īppend/edit the following text to it: obj-m = foo.o See how to install kernel headers under Debian / Ubuntu Linux or RHEL / CentOS / Fedora Linux. To be frank kernel headers are more than sufficient to compile kernel modules / drivers.

Untar kernel source code (tar ball) in /usr/src using tar command: You need running kernel source code if you don’t have a source code, download it from. Step 1 – Get Linux kernel headers source code
