Could not create vmnet interface, permission denied or no entitlement?

[jmreicha]

I am using the brew installed version of the xhyve driver, running the following command to create an xhyve machine.

docker-machine create --driver xhyve --xhyve-experimental-nfs-share test

And getting the following output (and error):

docker-machine create --driver xhyve --xhyve-experimental-nfs-share test

I am using binaries from the latest Docker toolbox release, docker-machine version 0.5.6, build 61388e9 with VBox 5.0.12.

I moved /etc/exports to /etc/exports.backupand then recreated an empty/etc/exports`.

The second time I tried to create the VM it worked.

Great work on this driver so far!

Deleting /etc/exports and recreating an empty file didn't work for me.
