crossbow discuss - May 2009 - Crossbow for Cloud Computing Architectures

Folks,

I just posted a paper which shows how Crossbow technology such as  
virtual NICs (VNICs), virtual switches, Virtual Wires (vWires), and  
Virtual Network Machines (VNMs) can be used as a foundation to build  
isolated virtual networks for cloud computing architectures. You can  
find the document here:

http://opensolaris.org/os/project/crossbow/Docs/crossbow-cloud.pdf

Enjoy!

Nicolas.

Hi Nicholas,
Could you please shade some light on how a queue (Fifo+Ring) in a
multi-queue NIC could be mapped to a Virtual Machine, using the
architecture and terminology outlined in this document? Also, how a
direct hardware access could be provided?
Thank you,
Eitan

With Crossbow the rings/queues/FIFOs are assigned to the VNICs by the  
MAC layer in dom0/host OS. The NIC classifier is then programmed to  
steer traffic to the VNIC rings according to the MAC address (+VID)  
assigned to the VNICs.

The architecture outlined in the paper relies on dom0/host OS to  
enforce the separation between VNICs and VLAN virtual networks. Note  
that hardware classification and offload of VLAN tagging/stripping is  
still possible in this scenario. To give guests direct access to the  
hardware would require the hardware to implement all these semantics  
in order to provide the same level of separation.
