Is the below statement accurate? Well, what does the statement mean? http://jclouds.apache.org/documentation/userguide/using-ec2/
VPC To create nodes in a subnet under Amazon VPC add the following option to your template options. Note that VPCs and Security Groups are mutually exclusive. I hope the statement above does not mean that it is not possible to designate a VPC and a given Security Group for a given machine instance. Per AWS doc and actual experience, a VPC, V, can have multiple subnets (S1, S2, S3), and a VPC can have multiple Security Groups (SG1, SG2, SG3, etc). An instance launched into S1 can choose either SG1, SG2, or SG3 as its security group. Similarly, an instance launched into S2 can choose either SG1, SG2, or SG3.
