Whilst this is perfectly fine for allowing internet access directly from the Guest, it does have some limitations, including the inability to connect via ssh from the Host machine.

VirtualBox supports four networking modes of which Network Address Translation (NAT) is the default.

CentOS7 (the Guest) – which you can download from hereīefore we get cracking, it’s probably a good idea to have a quick look at… VirtualBox Networking.VirtualBox 5.1.38 – available to download here.

Assign a static IP address to the Guest.

Create a Network Interface on the Guest to use the Host Only Network.

The specific steps I’m going to go through are : However, I’d also like to be able to connect the VM to the outside world occasionally so I can run package updates via yum. I’d like to be able to connect to these VMs directly from my host OS, just like a real-world server.

I want to setup a CentOS Virtual Machine (VM) that I can then use as to clone environments to host various software stacks that I may want to play with. Maybe someone was “Putin” ’em up to it ?įor my part, as I don’t quite have the space for a bunker at the bottom of my garden, I’ve decided to hide out in to a world of make-believe…well Virtual Machines at any rate. On the other hand there are those who are pushing for a new referendum because, apparently, some politicians lied when campaigning. As far as I can tell, they haven’t managed to offer any practical solution that they would accept as that would involve thinking about Brexit. On the one hand, there are those who are refusing to accept any solution offered to maintain a “soft” border on the island of Ireland. In their case, it manifests itself in slightly different ways. It’s a craze that’s even spread as far our political elite. 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).I’m currently indulging in the pastime that’s sweeping the country – trying not to think about Brexit. 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.
