FlexiNetwork: Cannot change network attachment

[Technologov]

VBox 3.1.x provides a way to change network attachment on the fly, which I call "FlexiNetwork".

In some cases this feature does not work.

Host: Windows Vista, 32bit, VBox 3.1.2 with 3 NICs (2 Ethernet and 1 WiFi)

Guest: [none] Empty VM, 1 vNIC

Steps to reproduce: (sometimes reproducible)

1. Start Empty VM (1 vNIC = NAT)

2. Switch network attachment type from "NAT" to "Bridged"

3. Choose the host's network adapter you wish to attach to

Actual Results: (sometimes) It automatically chooses the first host's adapter and user can't choose otherwise from the drop-down menu.

Expected results: It should ask the user which host's adaper he wanna use

Added screenshot. In this case both "Bridged Adapter" button and "Realtek" button became non-clickable.

I don't know about the empty VM or none, but it does work in a real VM. Why would anyone need to do this on an empty guest? Just curious.

[Technologov]

I have the same problem on any VMs.

It is more reproducible (not 100%) in the following way:

1. Start with NAT

2. Switch VM to bridged mode, attach to physical NIC 1

3. Switch VM to back to NAT

4. Switch VM to bridged mode, attach to physical NIC 2

5. Switch VM to back to NAT

Should work with VBox 4.2.
