Can't add ESXi hosts to vCenter 7

OK, I'm playing with the latest builds in my lab so I'm working on tuning the rebuild scripts which involve resetting the ESXi hosts to factory settings, deploying a new vCenter and then adding the ESXi hosts to create the lab cluster.

This process has been working just fine until just now where a freshly rebuilt VCSA simply won't integrate the ESXi hosts any more. In the powershell script, I get no errors at all, so I tried through the vCenter UI and I get the following types of messages :

There was an error encountered for host vhost1.infrageeks.lab. Reason: A general system error occurred: Error: N7Vmacore4Soap24InvalidResponseExceptionE( Unexpected exception reading HTTP response body: N7Vmacore15SystemExceptionE(Connection reset by peer: The connection is terminated by the remote end with a reset packet. Usually, this is a sign of a network problem, timeout, or service overload.)

Since this is a tear-it-down-and-rebuild-it process, I'm still working in evaluation mode at this stage.

From a troubleshooting perspective:

  • All the servers are on the same subnet
  • Everyone can ping everyone
  • From the console of the VCSA, I get back the login page when I try a curl -k https://vhost1.infrageeks.lab/ui/ so there is L3 connectivity
  • The ESXi hosts are working properly and I can login into their Web UI directly with no issues.
  • I added an extra machine to the process with a fresh ESXi install and it is responding the same way.
  • ESXi 7.0.0 (Build 15843807)

And it turns out to be an MTU problem on the switch. Nevermind...
