Dynamic Kernel Module Support (DKMS) for vRouter
Dynamic Kernel Module Support (DKMS) is a framework provided by Linux to automatically build out-of-tree driver modules for Linux kernels whenever the Linux distribution upgrades the existing kernel to a newer version.
In Contrail, the vRouter kernel module is an out-of-tree, high performance packet forwarding module that provides advanced packet forwarding functionality in a reliable and stable manner. Contrail provides a DKMS-compatible source package for Ubuntu so that if you deploy an Ubuntu-based Contrail system you do not need to manually compile the kernel module each time the Linux deployment gets upgraded.
The contrail-vrouter-dkms package
provides the DKMS compatibility for Contrail. Prior to installing
the contrail-vrouter-dkms package, you
must install both the DKMS package and the contrail-vrouter-utils package, because the contrail-vrouter-dkms package is dependent on both. Installing the contrail-vrouter-dkms package adds the vRouter sources to the DKMS database, builds the
vRouter module, and installs it in the existing kernel modules tree.
When a kernel upgrade occurs, DKMS ensures that the module is compiled
for the newer kernel and installed in the proper location so that
upon reboot, the newer module can be used with the upgraded kernel.
For more information about DKMS, refer to:
DKMS Ubuntu documentation at https://help.ubuntu.com/community/DKMS
DKMS Ubuntu manual pages at http://manpages.ubuntu.com/manpages/lucid/man8/dkms.8.html
