Hi Salvatore, Thanks for this nice synopsis of the issues that need consideration.
Specifically on the topic of VIF drivers - I do agree that it's rather cumbersome to deal with Quantum drivers in Nova. I think this issue would have been much easier to tackle with if there was one generic mechanism for the VIFs to always use. A bridge is indeed one way of providing for connectivity, but not all underlying technologies might always provide connectivity using a bridge. In such cases, since Nova has to bring up the VM, it still needs to know what interface type to use for this VM in the context of what networking technology is being used in that deployment.
