From my understanding boto module is not a part of salt-cloud, it is salt module.
I have checked this link, but we have some following issues with it
1) We are not using amazon web services, but AWS like API.
2) For salt cloud we have made changes in python ec2.py to make it working (signature version 2 was not supported here, so made changes in ec2.py)
3) How do I change the Signature Version in boto for managing security groups?
4) Where I can provide end URL in boto for managing security groups?
5) We can't create in new security group and attach it to running instance. (Our cloud provider is not providing this feature)
