Works on Docker-machine on Mac OSX?

Great presentation at DockerCon!

Running the most recent version of Docker-machine, and using Ubuntu:15.04 or Alpine:latest, I'm unable to run ipvsadm. No matter what I do, I get this error (any ideas?):

bash-4.3# ipvsadm
modprobe: can't change directory to '/lib/modules': No such file or directory
Can't initialize ipvs: Protocol not available
Are you sure that IP Virtual Server is built in the kernel or as module?

Hey,

IPVS support is definitely still in boot2docker images: https://github.com/boot2docker/boot2docker/blob/master/kernel_config#L972

Try to run:

$ docker-machine ssh default # or whatever machine name you use
$ sudo modprobe ip_vs

This should load the IPVS kernel module. Normally ipvsadm does it for you automatically though, so I'm not sure what happened there. Note that you should run ipvsadm and modprobe with sudo, since it requires kernel access.

solved by adding --privileged when running the container that will use ipvsadm, as well as upgrading to the newest version of docker-machine.
