I'm using the openvz kernel 2.6.32, and found that I can't netdev_add a
real net device to a container.
I found the function* __dev_change_net_namespac*e in net/core/dev.c, and it
says:
#ifdef CONFIG_SYSFS
/* Don't allow real devices to be moved when sysfs
* is enabled.
*/
err = -EINVAL;
if (dev->dev.parent)
goto out;
#endif
It seems if you enable CONFIG_SYSFS, you can't add a real device to a
container with the netdev_add command.
I'm confused about this, because under kernel 2.6.18, it's ok to add a real
device when sysfs is enabled.
Why forbid this?
and if I want to add a net device, How?
