Open Stack

Several thing in my mind:
a) NIC need more information like the switch, and these information need be managed by nova also. We have basic support, but not fully implemented.
b) How to setup the device, including the mac address or 802.1Qbh etc. Libvirt have several option to support it, need more work to support them, also need consider other virt driver like xenapi etc.
c) How to achieve the isolation of tenants, and how to setup like the router in Neutron. I'm not well on Neutron, but I think others may have more idea on it.

Thanks
