Requiring Global Identifier for '--image' option with 'slcli virtual create' command

[sudorandom]

Expected Behavior

This command will work:

slcli -y vs create --image=967301 --cpu=4 --memory=8192 --san --vlan-private=789 --datacenter=dal06 --hostname=ussj1d-scopclark-ws --domain=smartercitiescloud.com --private --network=1000Mbps

Actual Behavior

This command returns an error

slcli -y vs create --image=967301 --cpu=4 --memory=8192 --san --vlan-private=789 --datacenter=dal06 --hostname=ussj1d-scopclark-ws --domain=smartercitiescloud.com --private --network=1000Mbps
SoftLayerAPIError(SoftLayer_Exception_InvalidValue): Invalid value provided for 'blockDeviceTemplateGroup.globalIdentifier'. A valid global identifier is required for a template.

slcli vs create cannot accept an image id for the --image option and it is not clear from the documentation that you need to pass in the global identifier.

Environment Information

Operating System:
softlayer-python version (slcli --version): v5.0.0

Detail

The thing that we did change between version is slcli image list to show IDs instead of global identifiers. There's 3 ways to make this better:

1. Be more explicit in the description for the --image option for slcli virtual create
2. Show global identifiers in the slcli image list command again
3. Have slcli virtual create automatically translate the image ID to the image global identifier

I chose to implement option 3.
