The error message is pretty self explanatory. The VM you are trying to start needs hardware virtualization enabled. See the follwing Q&A on how to do so (provided your CPU is capable of this):
If this does not resolve the issue, the following steps may help:
- Reboot the host OS
- Try with fewer virtual CPUs starting from 1 only
- disable VT-x settings in VBoxManager (reported to worked but I doubt this)
- on a Hewlett Packard machine hardware VT-x could only be achieved with a BIOS update (source superuser.com)
Click "Discard" (Discard the saved state) option (option from the virtual box manager) and try starting the virtual box once again it must work . this usually happens when your host operating system sleeps while your virtual machine is still active . Please note any unsaved data will be lost .
Yes, for me that was the issue. Run the VB as an administrator. Right click on the VB, and select "Run as Administrator"
1It's that you need to run Virtualbox as an administrator.
