Hugo, I was just talking with the folks at Nicira, and had the current VMware integration approach explained to me. AFAIK, you end up needing to have a VM running OVS on the host, with two VMware virtual switches (one for your overlay transport, and one for your guest VMs to attach to). Was this the model you were considering working to orchestrate? Or were you considering waiting to see how the Nicira technology will be better integrated into ESXi?
One one hand, the current approach is absolutely a hack (and prone to performance issues). On the other hand, waiting for a better ESX/Nicira integration may take a good amount of time, and probably won't be backward compatible with older ESXi versions. Thoughts? -chip
