[lxc-users] LXC for real-time robotics

[Justin]

We are using LXC in a medical device which has hard real time requirements.
We use Yocto to build our embedded Linux distribution and have also used
the RT_PREEMPT patch. We have had good results and the only issues we have
seen were related to drivers that were fixed in upstream kernels. Once we
backported, everything runs smoothly. I can't say if LXC/LXD is a good fit
for you but it is a good fit for us as it has inherent properties that
mitigate some of our cybersecurity risks.
