W7 Host + Ubuntu Guest = No Bridged Networking

[x12Mike]

Greetings Folks,

I have been searching this issue up and down for the past few days, going over forum posts and Google... I cannot seem to find an answer why this is not working.

I am trying to migrate to VirtualBox from VMWare, so that is where my experience is. I have VB installed on my laptop, which has an Intel 82579LM Gig Card and an Intel Ultimate-N 6300 AGN card, wired and wireless respectively.

I cannot for the life of me get bridged networking to work with a guest at all. NAT works fine, but I prefer my guests to be bridged so other machines can access them.

• * I have tried various network adapters for the guest, including virt-io
  * This is not working for either wired or wireless adapter (Intel issue?)
  * Cable connected checkbox IS checked
  * And to note, I do have the Extension Pack Installed
  * VirtualBox Bridged Networking Drive IS checked off on both NIC's

For reference this is a Dell E6420 Laptop. I have been trying with Ubuntu primarily, 12.04 and now 12.10, same results across the board.

I am quite thoroughly confused, so any help/advise will be greatly appreciated!

Welcome!

You will probably get more responses if you tell us a little more, such as the host operating system, the guest operating system and the specifics of your error. For all I know, you are trying to get OS/2 to run under Mac OS X on your laptop and OS/2 only sees the network card when NAT is selected as the networking type.

Several specific questions come to mind:
* Does the problem affect different guest operating systems or only one? In other words, do Linux, XP, Vista, etc. guests all exhibit the same behavior?
* Is the guest a clean install or a migrated image from VMWare?
* What exactly goes wrong? Is the virtual network card visible from the guest? Does the guest claim to have an interface? Does your DHCP server see the guest and allocate an IP address?

Thanks,
Marty

I owe you an apology. You put the guest and host information in the title of this thread. Nonetheless, what kind of errors are you seeing?
