They don’t see the host OS nor other VMs running on the same resources.
The hypervisor emulates resources so the guest operating systems assume they are using all physical resources. The virtualization layer that abstracts the guest machine and underlying operating system is created with a hypervisor. Doing so reduces the number of physical dedicated servers required. Server virtualization allows you to run multiple operating systems on the same physical resources. It is used by everyone, from enthusiasts to developers. Add the rule “Host Port: 2222 Guest Port 22” then connect using the command ssh -p2222.Virtualization has become the norm for software and OS testing. If you see VirtualBox NAT IP 10.0.2.15, go to the virtual machine settings and click the Network tab then Port Forwarding. Press enter a few times at the login prompt to see an IP address pop up. Networking can take a bit of time to come up under VirtualBox, and the IP is needed in order to connect to it. Then click on the Storage tab and load the created config-drive into the CD/DVD drive.Ĭlick on the ‘OK’ button and the virtual machine will be ready to be started. Next, go to the settings from the created virtual machine. Then, choose ‘Use an existing virtual hard drive file’ and find the new cloned image.Ĭlick on the ‘Create’ button to create the virtual machine. Next, choose the desired memory size at least 2 GB for an optimal experience. Type the desired machine name and choose ‘Linux’ as the type and ‘Linux 2.6 / 3.x (64 bit)’ as the version.
Open VirtualBox Manager and go to Machine > New.
