คำตอบ Yellow Triangle over Network Icon after installing Virtual Box

    After installing Virtual Box on Windows 8 x64 consumer preview, which is a bear metal install, a yellow triangle with an exclamation mark in it, sits on top of the networking icon.  If I disable the Virtualbox network adapter the icon in the system tray appears normal.

    If the PC is booted up with the Virtualbox network adapter enabled (physical adapter is enabled as well), I am unable to browse the internet as IE states the webpage cannot be found and neither are any apps able to connect to the internet.  ipconfig shows the physical adapter as being disconnected and the virtual adapter with its static address settings.  Trying to use the /release or /renew switches gives a message stating no adapters are in a valid state for this command or something to that effect.

    The only way I have found to get the physical adapter working is by disabling the virtual adapter, waiting for it to connect and enabling the virtual adapter again.

    The physical adapter is a wired connection using DHCP to get an address

    **Edit**

    I have just tried setting the ip address of the physical adapter statically and rebooted the computer however I was still unable to access the internet after logging in.  Once I removed the static ip address on the physical adapter, I was able to access the internet again ok.

    Any ideas on how to resolve this issue?

    This s interesting as it sounds as if there is something that is not right with the way that VirtualBox does its network bridging with Windows 8.

    Have you checked the VirtualBox forums?

    There is also an issue that you will find in this forum with some similar known behavior when enabling Client Hyper-V.  you might want to search for those threads to see if the symptoms match.  In that case there is a yellow triangle but the networking seems to work after removing and recreating the virtual switch.

      I get the yellow triangle when I enable Hyper-V in the Win 8 CP but it does not affect anything (except some apps which complain about no Internet access). Both host and guest OSs have network access and work normally.

      I have never had any problems with bridged networking in VirtualBox in the past. Its bridge driver can co-exist with the VPC bridge driver. I haven't tried it in Win 8 CP because I am running Hyper-V and it won't co-exist with VirtualBox (without fiddling with bcdedit to load without the hypervisor).

    I see the same thing, actually. I'm using Hyper-V, and I created two networks. One is an internal network and the other is an external network, and I attached the external one to my wifi adaptor.

    In the "Network connections" I have a bridge network and an unidentified network. The latter appears on the main "network and sharing center" and is listed as "no network access" and I assume that is what is generating the yellow icon.

    This also does not affect anything as far as I can see. I think I did see one or two programs saying that there was no networking... but I've not seen it recently (could that have to do with a reboot??).

    Oh - apparently this yellow icon is a bug in the beta build: http://social.technet.microsoft.com/Forums/en-US/w8itprovirt/thread/88925e66-eaff-49ea-a8c6-37c90605fe9d Cool.

    Cheers, Gordon.

    fwiw Bill, VirtualBox runs without VT if you install it on the CP with
    the hypervisor running, it actually runs pretty well, even when running
    VirtualBox and Hyper-V VM's at the same time.
     
    Getting the networking to work right is another matter, and best served
    by more NIC's.  On my laptop I had to add a USB NIC for VirtualBox.

    There's a thread regarding this on the VirtualBox forums also. They aren't concerned...moderator responses

    "Current policy is that we don't want to waste time and bandwidth discussing issues with a host OS that isn't even released/finalised yet. We could be chasing our tails with issues that turn out to be Win8 beta bugs. "

    "Issues would be reported in this thread, just don't expect a formal response"

    Thank you all for responding, I have reinstalled Virtualbox with the latest version, 4.1.10 (was using 4.1.8) which seems to have addressed the network connectivity issue, now just need to wait for the bug fix for the yellow triangle on the networking icon. Thanks again.

    A similar problem persists for me for several months now: a "red crossed" network status icon in taskbar, although I *do* have Internet access all this time. But it is frustrating not to be able to use this indication.

    My OS is Windows 7 Home Premium 64-bit, SP1, all patches; on Acer AS3810T.

    It was there with VirtualBox 4.1.8, 4.1.10, and is still here with the very latest (released few days ago) 4.1.12.

    Stupid excuses from VirtualBox developers not accepted.

    Just wanted to say that I still see the behaviour above under Win8 x64 CP with VirtualBox 4.1.12-77245. Haven't found a reliable workaround. Sometimes rebooting will do the trick, sometimes it's disabling/re-enabling the wifi device or the virtual adaptor, other times the only thing that seems to work is threatening the device a life worse than death. For now, I've uninstalled VirtualBox.

    I wish that was actually a solution... :-\ We'll have to take it up with Oracle, I guess.

    The one thing that is painfully obvious from all the comments on this thread is that this problem is rooted with VirtualBox itself and not Windows.

    I too experienced the yellow triangle on my network icon after setting up Hyper-V. I remembered adding a second NIC to my server, because I read somewhere that Hyper-V is happier if it has its own network interface card for the virtual network. So I installed a second NIC in my desktop and the triangle went away.
