Every time a NIC is added to a VM using the vRA "reconfigure" action, a E1000 adapter is connected. I would like this to be a VMXNET3 adapter instead.
Is it possible to change this default setting in vRA? Changing the adapter type afterwards is problematic, because the VM has to be powered off.
Add this custom property "VMware.Network.Type" with a value of "VMXNET3" to your blueprint. The linked document has all the other usable values as well.
