I\'m getting this error while loading a Puppet image from a Oracle virtual box. How can I fix it?

Failed to open a session for the virtual machine learn-puppet-c

    Just try adjusting ( decrease ) your allotted RAM for the virtual machine in Motherboard in settings. The amount of RAM free in your system at that time might be less than the amount you have allotted for the virtual machine. This worked for me.

  • It happened to me too, and After reading all solutions, I've deleted the created drive and started all over.

    The first case (the one that didn't worked) was windows 7 64 bit.

    After trying the config as Win 7 32 bit that error didn't appeared again.

    Hope this helps someone.

    That's pretty simple problem to fix as you can see in the error message

    You don't have to go with the previous version of virtual box, rather try this

    go to your BIOS setting...

    inside the virtualization tab enable the virtualiation techniuqe

    restart your PC and you will have your Virtual Box up and running.

    I had the same problem. I enabled vtx in bios and it didn't worked. After a doublecheck in the bios I recogniced that the bios said that you have to poweroff (and realy power off) the computer. After that it worked. Heavy Pitfall :)

    I upgraded to Windows 10 x64 (from Windows 7 x64), had a VirtualBox Windows 10 x64 VM, but got the VT-x error. My BIOS was enabled, settings - everything in this post was addressed, but still got the VT-x error.

    What fixed it for me was to go to Lenovo and install the latest BIOS for my W550s ThinkPad. Once the upgrade was installed, VirtualBox gave me the x64 options again with no more VT-x errors.

    If you are running a W550s, the BIOS version I installed was from September 2015, "BIOS Update Utility" n11uj05w.exe, version 1.10 from the Lenovo website.

    When I try to set Base Memory around 4000MB (my pc have 8GB) I get the same error 'VT-x is disabled in the BIOS'. But when I reduce Base Memory to 2500MB it works and error is solved.
