“No network adapters were detected” while installing ESX 4 on VMware Workstation

Today I was trying to install ESX4 on my windows machine on top of VMware workstation 7.I and saw everything was fine but while installing the installer complains “No network adapters were detected”.For you reference I have attached the screenshot.


After searching a lot in google I found the solution.To get rid of this issue you just need to edit the <esxname>.vmx file.

make sure the following lines are present for each connected Ethernet adapter. If there are multiple cards configured for the ESX instance, there will be one copy of each of these lines for each adapter.

ethernet0.present = "TRUE"
ethernet0.virtualDev = "e1000"
ethernet0.connectionType = "bridged"
ethernet0.addressType = "generated"

If any of the line is missing you can add the entry at the end of the file.

Also You’ll need to add the following lines in the .VMX file if your processor is Intel-based:

monitor_control.restrict_backdoor = TRUE
monitor_control.vt32 = TRUE

If the processor is AMD-based, replace the line

monitor_control.vt32 = TRUE


monitor_control.enable_svm = TRUE.

Now start your ESX installation.You can proceed without any error.


15 steps to create your own VMware vSphere LAB on your home computer

VMware has given us the opportunity to test out all its product features for 60 days. So those who are preparing for VCP exam or those who want to test or learn vSphere features it will be very helpful to create a vSphere environment in their home computer. So don’t complain about VMware that you can afford the hardware cost, so you cannot test VMware.

Hardware you need

1. Mother Board having 64-bit compatibility

2. Processor with VT (Virtualization Technology) and x64 Supports

3. 4 GB of RAM (minimum)

Now a day all the motherboard and processor in the market contains these features. To see whether your current processor is 64-bit compatible or not and VT supported or not, you can use the following tool.

BITS: Download Link1

Download link2

Once you will run the program you will get a screen like below and can able to know all the facts.

Hardware that I used:

Processor:-Inter core 2 Quad CPUQ6600

Motherboard:-Intel DG31PR

RAM:-4 GB Transcend DDR-II 800MHz


1. VMWare workstation/server

2. Windows Server 2003/2008 64-bit

3. ESX/ESXi server ISO

4. vCenter Server ISO

5. Openfiler ISO

Software versions I have used

1. VMware® Workstation 7.1.2

2. Windows Server 2003 Enterprise x64 Edition

3. ESX 4.1 Installable ISO image

4. ESXi 4.1 Installable ISO image

5. VMware-VMvisor-Installer-4.0.0-171294.x86_64 ISO image

6. openfiler-2.3-x86_64-disc1 ISO image

Let’s Start our Lab

Step-1:-Install VMware workstation on your windows operating system.

Step-2:-Create 1 VM with 2.0 GB of RAM and install ESX from the DVD image.

Step-3:-Create 1 VM with 2.0 GB of RAM and install ESXi from the DVD image.

Step-4:-Create 1 VM with 2.0 GB of RAM and Windows Server 2003 Enterprise x64 Edition installed.

Step-5:- Create 1 VM with minimum 256mb of RAM and OpenFiler installed

N: B-Never reserve any memory for any host if you donot have more than 6GB memory as the memory usage may become constraint in powering some guest.

Step-6:-Mount VMware-VMvisor-Installer-4.0.0-171294.x86_64.iso to windows server 2003 VM and install vCenter Server (VC) in the same VM. Also install the vSphere client on the same VM.This will be our vcenter Server.

Step-7:-Install vSphere client in your Base operating system which is in my case Windows 7 64 bit.

Step-8:-Now put all the 4 VM’e in “Powerd On” state.

Step-9:-Open vSphere Client on your base operating system.It will ask username/password of vcenter server.You will get a screen like below.

Give the username and password of your windows 2003 server and press login button.

Step-10:-Once after successful login you will be presented a screen like below.

Step-11: Create a folder with name as per your convenience by right clicking on the vCenter server as shown in above screen.

Step-12: Create a datacenter with name as per your convenience by right clicking on the folder created in the above step.

Step-13: Now you can add host to the data center by right clicking on datacenter and selecting Add Host.

Step-14:-After adding host you can see them like shown below

Step-15:-Now you can click on the hosts and create virtual machines, resource pools etc. like shown below

This way you will get a testing environment for VMware vSphere.To test storage you can use Openfiler as iSCSI storage device.For more information on how to install and use open filer with vSphere you can go here.
