Here we can see, “vmware change network adapter type vmxnet3”
What is a VMXNET3 Ethernet adapter?
VMXNET3 (VMXNET Generation 3) may be a virtual network adapter designed to deliver high-performance virtual machines (VMs) running on the VMware vSphere platform.
VMXNET3 has equivalent features because of the VMXNET2 adapter but with added functionality to attenuate I/O virtualization overhead. To enable VMXNET3, VMs got to get on virtual hardware version 7 or later and should need VMware Tools installed, counting on which guest OS (guest OS) is getting used.
How To Change E1000 into VMXNET3 without changing a MAC address
You might find yourself during a situation where you’ve got a VM which you would like to vary vNIC type, but you would like to stay at the present MAC address. Today’s post will teach us the way to Change E1000 into VMXNET3 without changing a MAC address.
This is a simple post which I’m sure everyone knows the way to do. Still, many Microsoft people who are learning VMware technology aren’t that familiar as VMware admins working with the technology since its beginning.
MAC addresses are often tightened to some software thanks to licensing, or it is often some VM using telco software that needs a specific MAC address. Otherwise, it must be reconfigured.
The reasons are numerous. Sometimes you’ve got a hardware dongle, which causes even more troubles in virtualization as do not forget, our VMs are moving between hosts…
Using the VMXNET Generation 3 (VMXNET3) adapters in VMWare vSphere has better performance, less overhead, and lower CPU usage than the normal E1000 NIC or previous vmxnet generations.
The VMXNET3 adapter may be a new generation of a paravirtualized NIC designed for performance and isn’t associated with VMXNET or VMXNET 2. However, it offers all the features available in VMXNET 2. In addition, it adds several new features like multiqueue support (also referred to as Receive Side Scaling in Windows), IPv6 offloads, and MSI/MSI-X interrupt delivery.
How To Change E1000 into VMXNET3 without changing a MAC Address – The steps
Step 0: Power off your Virtual machine (VM) within the VMWare Console, remote console, or web client. Take a note or save the MAC address of the VM.
Step 1: Right-click the VM > Edit Settings > Next to the Network adapter, click the Delete sign.
Then you will see a message saying that the “Device are going to be removed.”
Step 2: Add, Click Add New Device, and choose Network Adapter > Choose VMXNET3 under Adapter type.
Then choose the right VM network you would like the VM to attach to, and do not forget to see “Connect At Power On” if you would like the VM to have network connectivity.
Step 3: Change the MAC address from Automatic to Manual, and enter the MAC address you’ve saved in Step 0.
Well, this is often about it. There’s how to vary network adapter via PowerCLI and “Set-NetworkAdapter” cmdlet. Some guides show how to roll in the hay via SSH or direct console access, where you modify the VM’s VMX configuration file directly. VMware communities link to see for a few further possibilities.
But whether the PowerCLI method is supported, the manual edition of VMX files …. I don’t think it’s supported.
But during this post, we could roll in the hay easily through GUI. However, while it is easy to try for a few VMs, it’d be more problematic for many VMs, where we certainly dug into some PowerCLI magic.
But confine in mind that VMXNET offers better performance than its previous generations in both Windows and Linux guests. This is because both the driving force and the device are highly tuned to perform better on modern systems.
VMware recommends migration to VMXNET3 if performance is your top priority. all of your templates VMs should already get on VMXNET3 for future deployments.

User Questions
1.Upgrade a Flexible Nic to VMXNET 3
I have been trying to find a process to upgrade nice but haven’t found anything related.
So I found a couple of VMs with Flexible Nic and would like to upgrade to VMXNET 3.
VM has the newest VMware Tools installed.
VM has the virtual hardware at version 8
OS does support the VMXNET 34 Adapter.
But the matter is that this VM is attached to the boot drive.
2.How do I specify Network Adapter to be vmxnet3 in Fusion?
I am running a Cent-OS VM in Fusion that will not boot if a vNIC is anything aside from vmxnet3.
When I add an adapter through Fusion UI, it creates an e1000 type, and that I can’t find how to switch this.
Guessing I probably got to edit .vmx directly, but I’d wish to know exactly what I want to feature.
3.Network adapter shows up in Device Manager but not in Network Connections
when I tried to feature a VMXNET3 network adapter on Windows Server 2016 Standard virtual machine, where the INTEL network adapter already exists (Adapter type: E1000E). It’s a VMware environment, and that I added a replacement network adapter through the vCenter (Edit settings).
So, I see the newly added network adapter within the Device Manager but not within the Network Connections. I attempted to update WMware Tools, remove, uninstall, and install the new adapter and VMware Tools – but always an equivalent situation: no visible within the Network Connections. So, standing within the Device Manager is “Working properly.” Additionally, the issue is that once I open Properties for the prevailing INTEL network adapter (Intel(R) 82574L Gigabit Network Connection) – I do not see anything (blank window)?!
