Check out this follow up post for some simple examples of the VM connecting directly to the network fabric. http://www.bradhedlund.com/2009/10/23/simple-use-cases-for-network-interface-virtualization/ Thanks for stopping by and leaving a comment.

My guess will be that VNIC1 and VNIC2 will need to be trunked to carry the multiple vlans. But in this case, how many vEth will there be in the Fabric? If it is still two vEth in the fabric, then we do not have one VM to one vEth mapping. My understanding of VNlink in hardware is that we want to achieve such that each VM is "directly" connected to the fabric. Your articles are great and i learn a lot from it. THanks Eng Wee Hi Brad,

If the server in your diagram is
- an ESX
- have stardard vswitch in it.
- have 5 VMs in five different VLANs load sharing VNIC1 and VNIC2 in your diagram

How will this be represented in the diagram?

Your articles are great and i learn a lot from it.
