vSphere – Networking – ESXi Single NIC VDS Management Migration

Well, I wasn’t sure how to name this blog as VMware continues to use all kinds of different lingos for all of their bells and whistles. I had the unique opportunity to begin working with migrating management interfaces or also know as vmkernel interfaces around from VSS to the DVS switching. This present a lot of struggles but it seems to me that VMware has really improved this functionality in the later versions of vSphere. I recall running into many kinds of issues when doing this on 4.0. So far using a vCenter 5 server with a mix of 4.1 and 5.0 host testing has proved to be seamless and non-interruptive. However, I would still highly recommend considering all your options and testing this method THOROUGHLY before ever touching production environments.

I was able migrate a single physical NIC running ESXi management from a VSS to a VDS. This video covers how I did that. The reason for the video was because I got all kinds of senseless google links when trying to search for something documented. So, I did myself a favor and published one.

Remember, this is a test and this is only applicable for me to use in a few environments. In most cases I use redundant NICs. Now the real kicker about this is that to migrate from a VDS to a VSS requires a bit more thinking and planning. Especially if you only got access to a single PNIC. Maybe I will cover that some other time… for now try to use two. Also, this may be a solution for environments running single 10GB and need to use PVLANS or centralize managment.
