Cisco Modeling Labs - Corporate Edition is scheduled for mid to late July. See http://cisco.com/go/cml
VIRL is being offered as a personal version, no support, no patching, no roadmap, and can be found at /dev/innovate or onePK Cisco web sites.
You can download the onePK version at https://developer.cisco.com/site/networking/one/onepk/sdk-and-docs/all-in-one-vm/index.gsp and sign up for the dev/innovate beta at http://dev-innovate.cisco.com/
I am the TME for Cisco Modeling Labs and you can contact me directly, or post here for other questions.
I have tried to sign up at http://dev-innovate.cisco.com/ but it looks that theres is an error with the form!
Can you check what is the issue please?
you can edit the .virl file and run 50 or 100 vIOS instance if you want and have the RAM (384MB per instance)
look at my example virl file here :
i even created a patch to the python vmcloud python lib to have inline router config (within the virl file)
