This kernel module implements a basic interface to the IVSHMEM device for LookingGlass when using LookingGlass in VM->VM mode.
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.
This module requires the uio module to be loaded first, loading it is as
simple as:
modprobe uio
insmod kvmfr.ko
You can install this module into DKMS so that it persists across kernel upgrades. Simply run:
dkms install .
Simply modprobe the module:
modprobe kvmfr
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
