How to ping ubuntu guest on VirtualBox
I have an VM (VirtualBox) with Ubuntu. Host machine is Windows 7. How can I ping my Ubuntu from host and vice versa? Trying to set "Bridged" connection type in VM settings but there is no effect, I only lose my internet connection in Ubuntu.
Answer
In most cases simply switching the virtual machine network adapter to bridged mode is enough to make the guest machine accessible from outside.
Sometimes it's possible for the guest machine to not automatically receive an IP which matches the host's IP range after switching to bridged mode (even after rebooting the guest machine). This is often caused by a malfunctioning or badly configured DHCP on the host network.
For example, if the host IP is 192.168.1.1 the guest machine needs to have an IP in the format 192.168.1.* where only the last group of numbers is allowed to be different from the host IP.
You can use a terminal (shell) and type ifconfig (ipconfig for Windows guests) to check what IP is assigned to the guest machine and change it if required.
If the host and guest IPs do not match simply setting a static IP for the guest machine explicitly should resolve the issue.
