Hi Titus, please can you extend the issue and explain with a higher level of detail what kind of tests you did?
Can you ping the vm IP? Can the vm ping the gateway?
Check VM Network card:
Activate nic adapter.
Connected to bridge
Name: the physical nic card that you use to reach your network.
the following config works for my virtual box SKUDONET CE 7.
Anyway, It seems more of an issue with the virtual NIC configuration in the Virtual Box. As soon as the machine is reachable you should log in with the root user and password you configured in the installation process.
