AMD-V not enabling in bios with Ubuntu 14.04 - Vagrant Up fails

If you are like me you have been running around in circles trying to fix this. I cannot enable AMD-V even though it says enabled in the BIOS. I am simply trying to utilize puphpet to do a vagrant up

Here is my hardware/software

  • Lenovo Edge E545 (AMD)
  • Ubuntu 14.04 LTS
  • Vagrant 1.6.3
  • VirtualBox 4.3.12 (4.2.24 attempted as fail-safe)
  • BIOS version 1.09 (1.12 out but only has minor upgrades - nothing with AMD-V)

Here is what I tried

  1. Clean install of Ubuntu 14.04
  2. Installed VirtualBox and tried running vagrant up with multiple versions
  3. Tried turning the BIOS setting for AMD-V on and off
  4. Tried turning virtualization off and on in Virtual Box settings
  5. Set processor to 2 and 1 in VirtualBox settings
  6. Downloaded and installed 32bit virtualbox to 'try'.

resolution?: So I contacted Lenovo and AMD but both are pointing it towards being a software issue. The Lenovo rep. recommended I return the laptop and get something Intel based. Strange, but that is how I am "fixing" it.

FIX: Setting the 'virtualization' option to 'Disabled' in the BIOS fixes it.

VT-x or AMD-V is required to run hardware accelerated virtualization, in this case lovely VirtualBox.

Run to see if your CPU is capable of AMD-V.

egrep -wo '(vmx|svw)' /proc/cpuinfo

You should expect a couple of (# of cores) svw in output.

When trying to bring up the VM using vagrant up, try to enable debug output by using vagrant up --debug to see more information. Update your question with more information.

I have not used this machine in a while but wanted to post back on what I found.

I continued to search around for answers and found nothing. So I decided to go into the BIOS and change options until I found it to work.

I set Virtualization in the BIOS to 'Disabled' and can now boot to VMBox 64bit machines without error.

I hope this helps another soul.
