Subject RE: [jira] [Created] (CLOUDSTACK-1043) Add AWS Style NIC support
Date Wed, 23 Jan 2013 19:07:44 GMT
As for Security Groups, CS has a table "security_group_vm_map" to track which VM is in which
SGs, since SG will be changed to NIC level, this table might be changed to "security_group_nic_map",
and upgrade needs to be handled, listVM API lists SGs on which this VM is in as well, listVMresponse
might need to represent which SGs is on which NIC.

As for VPC, I found below links,
