Virtual Box doesn't show the network adapters

[Sandro Meira]

Hello VirtualBox friends,

I have used a image from a PC with windows 8 to create a virtual machine. The virtual machine was installed perfectly, but the network adapter isn't shown in it.

The network adapter isn't show in Virtual machine

I'm using a NAT connection in VirtualBox.

I'm using the same settings in others VM in the same PC, but in this VM it doesn't work

I have tried use a bridge network adapter, but it didn't work.

I need use this image because I need the same enviroment in my VM used in a real machine.

Attached it's the settings of the network adapter in VM.

Someone knows a solution for that?

Thanks a lot,

I have used a image from a PC with windows 8 to create a virtual machine.

What does that mean? Did you do a Physical-to-Virtual (P2V) operation? How?

The virtual machine was installed perfectly, but the network adapter isn't shown in it.

What adapter? Your original adapter or your virtual adapter? Because if you're expecting the original, forget it.

BTW, the picture that you've attached doesn't show the Network Adapters, it shows the Network Connections. Are you sure you're looking at the right place?

Hi,

I work in a company that create a image from one machine and put it in a area where the technicians can get it and apply in machines around the world.
I caught this image and I created a VM using this image. It worked very well, only the network card doens't work. The first image show the network connections of virtual machine.
Off course, I can't see the network adapter of the original machine (Realtek), but I can't see or add any network card.

Thanks,

I still don't understand exactly what you're talking about, I'm sorry. Do you have any adapters yes or no? Because that 1st picture is not supposed to show the network adapters. From the guests, open a Command Prompt and post the output of the command:

• ipconfig /all

It may be that you need to remove and re-add the NIC, or that you need to reset the network configuration, or the PlugAndPlay drivers. Don't expect a P2V to be an exact replica of your original. Your VM has virtual hardware...

Your screenshot above shows that you changed the virtual network adapter in the advanced NAT settings from the default "Intel PRO/1000 MT Desktop" to the "Intel PRO/1000 T Server" adapter (or used a VM template for a different OS version).
Windows 8 doesn't support the "Server" version of this adapter.
Could you try shutting down your VM completely, changing this setting back to the "Desktop" version of the virtual network adapter and try again?

[Sandro Meira]

Sorry, it was my mistake when I got the picture of screen.
I've tried with the "Intel PRO/1000 MT Desktop", but it doesn't work too, as you can see in the attached file.

Thanks,

See below the result of ipconfig /all.

Thanks,

Yeah, something's screwed up. Go to your DeviceManager and remove every single network card in there. Then refresh to see if the network card is detected again. Reboot in between or at some point that the configuration changes.

[Sandro Meira]

I removed all network cards, but the OS doesn't remove them.
I removed the others devices, and after the refresh they return like before.

In your last device manager screenshot, you see an unconfigured Ethernet Controller device under Other devices
Since you have selected Intel PRO/1000 MT Desktop (82540EM) as the virtualized adapter that VirtualBox provides to windows, you now need to configure that Ethernet Controller. You're likely needing a driver install.

Intel Ethernet Adapter Complete Driver Pack is likely what you'll want to install. You can find it by googling.

Try this and you should see your network adapter show up.

Hello,

I did the download of driver with this link: https://downloadcenter.intel.com/pt-br/ ... duct=50485
I tried to install the driver, but the Windows 8 in virtual machine, answer me that can't find the driver. See below the print screens. For all others devices I have receive the same answer.

I would like to see the "recipe" of the VM, the ".vbox" file:

1. Right-click on the VM in the VirtualBox Manager. Select "Show in Explorer".
2. ZIP the selected ".vbox" file and attach it to your response.

[Sandro Meira]

Hello,

See attached the zip file.

Thanks,

[socratis]

Your .vbox file looks OK. The problem is in your Windows, not VirtualBox, Windows is simply confused.

Go to the Device Manager and delete the devices that have a question mark. Reboot your Win8. See if the device gets detected in the Device Manager. Try to refresh the devices...
