Need to install vagrant-rancher plugin before doing vagrant up

[mickengland]

Vagrant up starts the server but then gives this error for the hosts:

"The guest operating system of the machine could not be detected!
Vagrant requires this knowledge to perform specific tasks such
as mounting shared folders and configuring networks. Please add
the ability to detect this guest operating system to Vagrant
by creating a plugin or reporting a bug."

$ vagrant --version
Vagrant 1.9.1

$ VBoxManage --version
5.1.16r113841

Running vagrant plugin install vagrant-rancher fixed this.
