We are using lxc(centos image) in our production systems on OL7/CentOS7 kernel 3.10. And it is ok. (Thank you
Also, we started using Debian 9/10(Kernel 4.15/5.0), and we’ve transferred some containers to Debian from CentOS7. And it works fine on another kernel.
But I hope you can explain, how containers work on different kernels, for instance, 3.10 and 4.15?
Are there differences? What we have to expect in case of migration from 3.10 to another kernel?
