Trying to start VM from console, but unsuccessful:
lexus@lexus-H110M-S2H:~$ vboxmanage startvm 21eaceac-f85e-4622-a52b-c586352aa9eb Waiting for VM "21eaceac-f85e-4622-a52b-c586352aa9eb" to power on... VBoxManage: error: The virtual machine 'centos7-ast-16' has terminated unexpectedly during startup because of signal 6 VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component MachineWrap, interface IMachine
The solution is "--type headless" option:
lexus@lexus-H110M-S2H:~$ vboxmanage startvm 21eaceac-f85e-4622-a52b-c586352aa9eb --type headless Waiting for VM "21eaceac-f85e-4622-a52b-c586352aa9eb" to power on... VM "21eaceac-f85e-4622-a52b-c586352aa9eb" has been successfully started.
