Select your virtual machine, then click Settings under the Actions pane. Select New virtual network switch, select Internal, then click Create virtual switch.Įnter a name for your switch, then select Internal Network. Select your virtual machine, then click Virtual Switch Manager under the Actions pane. If you already do, proceed to launch the Hyper-V manager. If you don’t have already have a virtual machine setup, check out our previous article for instructions. That’s not important to me, but if you want these settings to persist it’s not difficult, and is well-documented elsewhere (start with Ubuntu’s wiki, linked above).Share Your Network Connection with a Hyper-V Virtual Machine Note that these will be flushed upon reboot. That’s as simple as setting up IP forwarding on the development laptop and enabling a few firewall (iptables) rules to setup the NAT. I didn’t care about the latter– I just needed internet access from the VM. Normally, in this setup, the VM would attempt to use the development laptop as a NAT gateway for external access, but since our laptop isn’t setup that way, the VM can’t see the internet nor is it accessible from the internet.

eth0: Host-only interface connecting to laptop’s vboxnet0.

I disabled DHCP to reproduce production setup.

vboxnet0: VirtualBox’s host-only interface (creating these is well-documented).

This is actually pretty easy, especially after reading Ubuntu’s Connection Sharing wiki page. Since I’m trying to reproduce a production system in VirtualBox for testing purposes (which is how I typically use it), it stands to reason that I want the VM setup as close to the real thing as possible. However, I’m trying to test out some new networking ideas for my OpenStack Network node, and it doesn’t have a NIC configured with NAT. Of course, you’re saying “There’s a better way to do that!” And of course, I agree: with no other considerations, the best way to do this is to simply add another NIC to the VM configured as NAT instead of host-only.

I ran into the need to access the internet from a VirtualBox VM via host-only networking.
