Cannot create VM on SoftLayer from private iso Image

Hello,
I have successfully created VM on SoftLayer with Docker Machine via SoftLayer API with public image (for example UBUNTU_LATEST). But I want to create VM from imported private image. When I try it with private image, I got this error:

Error creating machine: Error in driver during machine creation: Error creating host: "Error in response: Invalid value provided for ‘operatingSystemReferenceCode’."

Is it possible at all via Docker Machine ?
Here is my Docker Machine command:

docker-machine create
–driver softlayer
–softlayer-hourly-billing
–softlayer-user $USER
–softlayer-api-key $KEY
–softlayer-cpu $CPU
–softlayer-memory $MEM
–softlayer-domain $DOMAIN
–softlayer-hostname $HOSTNAME
–softlayer-region $REGION
–softlayer-image $IMAGE_NAME

OS version: Linux docker 3.19.0-25-generic #26~14.04.1-Ubuntu SMP Fri Jul 24 21:16:20 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Docker Machine version: docker-machine version 0.6.0, build e27fb87

Thank you

Specify the provider’s image flag and one of its available images.

“For cloud providers, the base operating system is the latest Ubuntu LTS the provider supports”

“To use a different base operating system on a remote provider, specify the provider’s image flag and one of its available images.”

Thank you for your answer.

I got it, docker machine does not support private images imported to SoftLayer, because my image is not listed in available images although I can see my image successfully imported via web gui.
