title: How can I downgrade CentOS 6.5 to CentOS 6.3 on VirtualBox 4.3.10
body: <p>I ran the yum on CentOS 6.3, so that it turned into another kernel CentOS 6.5. After restart of the VirtualBox I couldn't anymore run neither the old nor the new OS. Do you know a way to downgrade to CentOS 6.3? How can I get into the machine with SSH without knowing it's IP address?</p>
