Please help: BIOS Virtualisation enabled but cannot start cloudera

[#1]

I am doing the coursera course in big data.

I followed the instruction and did the installation. I realised then i had to enable the Virtual Technology in BIOS (which was enabled anyway). However, i still get the same error:

'Failed to Open a session for the virtual machine cloudera-quickstart-vm-5.4.2-0-virtualbox'

The virtual machine 'cloudera-quickstart-vm-5.4.2-0-virtualbox' has terminated unexpectedly during startup with exit code 1 (0x1). More details may be available in 'C:\Users\badao\VirtualBox VMs\cloudera-quickstart-vm-5.4.2-0-virtualbox\Logs\VBoxHardening.log'.

Result Code:
E_FAIL (0x80004005)

Component:
MachineWrap

Interface:
IMachine {b2547866-a0a1-4391-8b86-6952d82efaa0}

Please help me with a comment

Hi @bsaad 

Thank you for helping me with the logs, Sounds like a "Hardening" issue, if that is what to be mentioned by VirtualBox Community.

Please read these and triage the situation based on your System Specs:
