Is checking for CONFIG_NET_NS=y in the .config file of the kernel,
sufficient for verifying the NETNS support ?
You can't guarantee that the running kernel was built with a given
config. There's a kernel flag that you can enable to store the kernel
config in /proc/config.gz, but kernels aren't often built with this flag
set.
libvirt checks the output of "ip --help". If netns is listed, then both
ip and the kernel have NETNS support. You could do a similar check in
const.py
Thanks!
