Using HP laptop? I had an issue using Vagrant with VirtualBox on HP machine. The root cause of the issue was that the PC system not enabled with VTx technology. To enable VTx option on HP laptop:
- Reboot the system and then hit “Esc” key
- Jump into “device configuration” to set device bios options
- Select “Advanced” tab
- Check the option on “Vitualization Technology(VTx)”, save it and exit
- Reboot the system
