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.
