No bootable medium found error VirtualBox

Migrating from physical to virtual or P2V is a common thing to do. In this virtualization era.

If hardware or a server is showing some issues, like rebooting by itself when no changes are made and the server is at the age of a primary 3 kid. Then this could be that the server is showing some signs that it needs to be retired.

P2V is a good option if an existing powerful server that is not fully utilized and is able to handle another load.

Migrating from OpenStack or exporting OpenStack VM to a volume so it can be used outside of OpenStack is another practice also. But sometimes things don’t go smoothly and few bumps or issues here and there may arise at times.

For example doing P2V in VirtualBox for a Linux system shows an error, “FATAL: No bootable medium found! System halted.” And you let the VM run for hours hoping that it will just boot by itself but it won’t just budge the error persist no matter how long you wait.

P2V is migrating or cloning a physical server to a virtual environment, which basically means that whatever things that is on the Physical server must also be present on the virtual system.

The OS that is being migrated to virtual, will have the same settings as it was originally installed on a Physical server, for example if the Physical server uses serial connection or has a serial dongle then when it is migrated to virtual then it will look for a serial port as well.

By default, in VirtualBox serial port is not enabled. Thus, sometimes will result to a “FATAL: No bootable medium found! System halted.” Error.

In my case I got this error when doing P2V but I realized that Physical server does use serial port. So, adding or enabling the serial port in VirtualBox does resolve the issue.

However, adding or enabling serial port in VBox still got error. Then you need to inspect the Physical server, maybe there are other dependencies or options that is needed and has to be present in the VM machine. Or simply, it is just another issue that requires time and troubleshooting.

Please find images below for the error and enabling serial port in VirtualBox.


Cheers. Till next time.

Notepad++ convert multiple lines to a single line and vice versa

WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided.
