Can you change the virtual NIC type after building a VM?
When building a VM, you can select which virtual device type you would like a vNIC to be (E1000, VMXNET3, etc).
After the VM is created, can you change the type of vNIC in use on a given connection (eg from E1000 to VMXNET3)?
If so, how?

How do I give label to vSwitches on VMWare?
I've searched extensively trying to name the vSwitches that I create, but all I can name them are "vSwitchX" where x= some number. How do I give these switches names? I'm using the Web Client.
Thanks!

faking NAT with a VMware distributed switch across multiple hosts
I need to construct a NAT for certain machines within the network. Wish to do this with dvSwitch - as it seems the logical way of attacking the problem as in this scenario there's just under 30 hosts.
In order for the NAT'ed VM's to have access to…

Where do all the little vEthernet (Default Switch) come from?
Potentially related to this question or that one, I currently have 16 "vEthernet (Default Switch)"es around ("Standardswitch" in German, though I doubt l10n has anything to do with this). All but one are in a "cable not connected" state.
