It took me a while to track this down but I believe there is a problem that is specific to this combination.
When deploying/upgrading a FreeBSD guest using the above combo, the network throughput is (the best I can describe it)... abysmal. Going as low as just a few bps. If I migrate the virtual machine to an ESXi 6.5.0 host, the network performance returns to reasonable/normal levels. If I change the network interface type to Intel E1000, the network performance returns to reasonable/normal levels. If I take a 12.0 or 11.3 machine using VMXNET 3 and upgrade it to 12.1, the same problem occurs.
I do not see any kernel messages on the console, nor in the system logs. I do not notice anything out of the ordinary during boot up.
What can I do to help track down the root of the problem, what should I dig into in order to post a meaningful bug report that will (hopefully) lead to a solution.
- 12.1-RELEASE (amd64)
- VMware ESXi, 6.0.0, 9313334
- Virtual Adapter Type: VMXNET 3
