In 12.10 beta2, VirtualBox has no access to network

[ealthuis]

After installing the 12.10 upgrade, Virtual Box running W XP has no connection to the network. This is new, as the installation of 12.10 has correct access. VBox never had the problem. I think it may be because of the new kernel 3.5.0-16 generic. It is also possible, that the VBox needs to be recompiled. Unfortunately I do not know the ocrrect command to do so.

Status changed to 'Confirmed' because the bug affects multiple users.

I can confirm this with host ubuntu 12.10 beta 2, and guest ubuntu 12.04

[Scelt (scelt)]

Can be temporarily fixed this way:

Open a terminal and try this:

VBoxManage modifyvm "VMNamexxx" --natdnshostresolver1 on

VMNamexxx is the name of your VM machine.

I can confirm the bug exists in 12.10 release (64 bit)

Check Launchpad #211727, It has a fix.

Make sure you have started VBox, as that is the only way to get access to the 'settings'

Thanks for the suggestion. In fact I did what Scelt suggested and it works now. But at least I have another solution now too!

How do I obtain "VMNamexxx" ?

" I fixed that by switching to the 64 bit option in the vbox settings. I switching to bridged networking from NAT restored the internet to Windows."

Worked for me.
