I have a Macbok Pro 13" and I'm using virtualbox to run ubuntu 12.04. My problem is I can't resize ubuntu for occupy the 13" of my screen when I use full-screen mode. Ubuntu only allows me to use two screen size options, 1024x768 or 800x600. The 800x600 option is too small, and cuts the screen in a smaller size with black edges.With the 1024x768 option, i only have black edges on the left and on the right. Is there any option for extending the image at the whole screen?
There's one extra step I needed in order to get Guest Additions to work on MacOS Mojave. With the VM shut down, go to VM Settings -> Display -> Screen. Enable 3D acceleration and max out the RAM (128MB works for me but virtualbox.org recommends 256MB). You can then restart the VM with your newly full-screened situation.
I have a virtual machine on a macos, within that virtual machine I have a Debian distribution and I want to use Wireshark to capture all the traffic from the lan network, from virtualbox. I have configured the network adapter as:
I have tried with all possible connections, Wireshark captures the Kali Linux traffic, but not from Macos and not from the local network (such as a telephone). Does anyone know what could be happening? Has it happened to anyone else?
Oracle VM VirtualBox uses a device driver on your host system that filters data from your physical network adapter. This driver is therefore called a net filter driver. This enables Oracle VM VirtualBox to intercept data from the physical network and inject data into it, effectively creating a new network interface in software. When a guest is using such a new software interface, it looks to the host system as though the guest were physically connected to the interface using a network cable.
The VM's bridge adaptor works in a similar way; the bridge device of your VM will have it's own MAC address and to your router it will appear that there are two devices on one wire. On the host os (OS X in your case), these are further filtered, so that the VM only receives packets addressed to the VM.
