Pre-create checks fail when creating a Hyper-V machine. PowerShell module is not available.

[corthon]

I have verified multiple times that the PowerShell management module is installed.
Currently working with:
Version 18.03.0-ce-win59 (16762)
Channel: stable
d70d80d

I may uninstall and try a previous version.

PS C:\WINDOWS\system32> docker-machine create -d hyperv --hyperv-memory 4096 default
Running pre-create checks...
Error with pre-create check: "Hyper-V PowerShell Module is not available"

I tried a workaround provided by @ramit-rulz: downgrade docker-machine and it did work for me, but only to uncover another issue down the road... "This machine has been allocated an IP address, but Docker Machine could not reach it successfully"

@LeonardoMontano This error is because by default Hyper-V allocates only IPv6 IP. For IPv4, you need to create External Network Switch

Try creating new docker machine using this command -
docker-machine create -d hyperv --hyperv-virtual-switch "<NameOfVirtualSwitch>" <nameOfNode>

@LeonardoMontano and @samirsyed, thank you very much! It worked. Couldn't figure out how to find the older version on my own.

[corthon]

Reopening because the underlying issue still exists. Was able to work-around with above suggestion.

Thank you @samirsyed Yes, I create an external switch and I still get the error. More details on issue #4440

Here is the solution

https://github.com/docker/machine/releases/download/v0.15.0/docker-machine-Windows-x86_64.exe

Save the downloaded file to your existing directory containing docker-machine.exe.

For my system this is the location for docker-machine.exe
/c/Program Files/Docker/Docker/Resources/bin/docker-machine.exe

Backup the old file and replace it file with the new one.

cp docker-machine.exe docker-machine.014.exe

Rename the downloaded filename to docker-machine.exe

mv docker-machine-Windows-x86_64.exe docker-machine.exe

Build Instructions

1. Create virtual switch in Hyper-V manager named myswitch
2. Request Docker to create a VM named myvm1

docker-machine create -d hyperv --hyperv-virtual-switch "myswitch" myvm1

Results

docker-machine create -d hyperv --hyperv-virtual-switch "myswitch" myvm1

You need to create vswitch in Hyper-V Manager (you can find it by search in you OS). As example, watch this video https://www.youtube.com/watch?v=cGlrw4P-VUQ
