Turning off the Host-Only adaptor and going back to a bridged connection brings SSH back online and functional.Socratis wrote:Follow the steps below. It isn’t an issue with the firewall, and “systemctl status sshd” shows the service remains active. SSH returns a “connection refused on port 22” error. The second, more challenging issue is that I can’t ssh in after successfully configuring the network. In the system-generated script, which contained several settings, I had to change the BOOTPROTO from “dhcp” to “static,” then add the IPADDR and NETMASK settings as suggested and reboot the VM (“systemctl restart network” didn’t work for me) to get the network active. I couldn’t get the network connected because the script you suggested contained a setting that conflicted. One I was able to resolve still working on the other one. In the meantime, I will have to struggle with a Bridged connection.įirst, the system created its own script for my Host-Only connection in /etc/sysconfig/network-scripts. Two years later, I had a couple of issues on Oracle Linux 8 (which is similar to CentOS and RedHat Enterprise 7/8). Installing CentOS 7Ĭreating a CentOS 7 VM is covered well in other places (I used Jeramy Singleton’s guide), so I won’t cover all of the steps here. But, if you’re using a wired workstation or you don’t have a lot of configuration dependent on the VM’s IP address, bridged networking might be a good solution to get you both internet access and host-to-guest networking. Also, I really need a static IP address for the VM to configure the Ansible scripts and because part of the process is to generate a self-signed SSL certificate for the VM’s IP address. This is exacerbated in my case by the fact that I exclusively use wireless networks on my laptop, so my network is regularly changing. Whenever the network the host is connected to changes, the IP address of the VM will change. Now you might be wondering, why not just use a bridged network adapter? Well, you can, but there is one substantial downside.

This allows host-to-guest communication but this virtual network has no access to the internet.

Host-only – with this mode VirtualBox creates a virtual network that the host and the VMs are connected to.

Host-to-guest communication and internet access are available. The VM gets an IP on the same network that the host is physically connected to.

Bridged – with this mode VirtualBox uses a special driver for the host’s physical network interface to create a virtual network interface for the VM.

This gives internet access but applications running on the host can’t make network connections to the VM.

NAT – the networking mode of the default network adapter when you create a new VM.

You can read all about the various networking modes here but here’s a quick summary:

and then add a host-only network adapter and configure the VM with a static IP address (for host-to-guest access)Ī quick word about VirtualBox networking modes.with the default NAT network adapter (for internet access).In summary, the approach I’ll give here is to create a VirtualBox VM: It turns out that getting this set up is not so trivial, but also, it’s not that hard once you know what VirtualBox provides and how to configure it. That means I need Django running on my laptop to be able to access the VM (host-to-guest access) and the VM does need to be able to access the internet (guest-to-internet access) since the Ansible playbooks that are executed against the VM download and install software from the internet. The goal is to have a locally running instance of Airavata that I can connect to when developing the Airavata Django Portal which I’ve been working on. Recently I’ve been working on installing Apache Airavata in a VirtualBox VM running on my laptop using our “standalone” Ansible installation settings.
