1.1 KiB

This kernel module implements a basic interface to the IVSHMEM device for LookingGlass when using LookingGlass in VM->VM mode.

Compiling (Manual)

Make sure you have your kernel headers installed first, on Debian/Ubuntu use the following command.

apt-get install linux-headers-$(uname -r)

Then simply run make and you're done.

Loading

This module requires the uio module to be loaded first, loading it is as simple as:

modprobe uio
insmod kvmfr.ko

Compiling & Installing (DKMS)

You can install this module into DKMS so that it persists across kernel upgrades. Simply run:

dkms install .

Loading

Simply modprobe the module:

modprobe kvmfr

Usage

This will create the /dev/uio0 node that represents the KVMFR interface. To use the interface you need permission to access it by either creating a udev rule to ensure your user can read and write to it, or simply change it's ownership manually, ie:

sudo chown user:user /dev/uid0

Usage with looking glass is simple, you only need to specify the path to the device node, for example:

./looking-glass-client -f /dev/uio0 -L 16
