I just installed docker and tried to create a Windows (not Linux) docker machine but it failed?
PS C:\> docker-machine.exe create --driver hyperv default
Creating CA: C:\Users\...\.docker\machine\certs\ca.pem
Creating client certificate: C:\Users\...\.docker\machine\certs\cert.pem
Running pre-create checks...
Error with pre-create check: "Hyper-V PowerShell Module is not available"
I downloaded the newer version of docker-machine
(https://github.com/docker/machine/releases/tag/v0.15.0) and a new error occurred.
PS C:\> .\bin\docker-machine-Windows-x86_64.exe create --driver hyperv default

Error with pre-create check: "no External vswitch found. A valid vswitch must be available for this command to run. Check https://docs.docker.com/machine/drivers/hyper-v/"
