It's not normal to see those kinds of NIC timeouts in a VM either.
I'd make sure your ESX or VMWare install is completely current first, and upgrade the VM hardware compatibility as far as possible. Also make sure the selected OS version matches what you have installed. The exact text will vary depending on your ESX/VMware version but it should be set to FreeBSD 11.x 64-bit.
