Docker-machine starting server

I just created a new docker-machine instance running on VirtualBox on Centos 7. Initially I started rancher-server via docker daemon but then saw that there was an available system service. I enabled it and attempted to start it and got this:

ERRO[0000] non-200 http response: 404
ERRO[0000] Failed to load service(kvm-vm-tools): non-200 http response: 404
No such service: rancher-server-stable

I didn’t enable or start kvm-vm-tools on this machine. What’s the best way for me to run rancher-server in docker-machine?
