While I’ve historically been a fan of the VMXNET3 interface, everyone should be aware of this behavior. This also happens when using Veeam Backup and Replication’s SureBackup functionality. The behavior in question is that when a Windows Server 2008 or Windows 7 virtual machine is cloned or otherwise incurs a change to the MAC address the virtual machine will re-enumerate the Ethernet interface. The VMXNET3 adapter is one of the new paravirtualized devices that are part of the vSphere compliment of technologies. Recently in an internal discussion and lurking through the Veeam Forums, the VMXNET3 virtual adapter came up in regards to its behavior when a MAC change occurs.
