When I attempt to start Ubuntu 14.04 in a VM I get this error (I have not started it before):

VT-x/AMD-V hardware acceleration is not available on this machine

What can I do?

Enable "virtualization" in your boot settings. It is "off" by default in most laptops.

As pointed out by Aizuddin Zali , may be vendor have locked in "Virtualization". Therefore can you just inform what Machine (machine number , company) you are using?

    this also can be really a CPU that doesnt have virtualization dont you think? Vendor also can lock the virtualization capability in certain laptop/pc. – Aizuddin Zali Oct 16 '15 at 15:48
  • @Aizuddin Zali , I think most CPU support virtualization nowadays. – silverwolf Oct 16 '15 at 15:57
  • most but not all, and we cant answer based on assumption. And we need to check as well if the vendor locking the virtualization or not in BIOS. – Aizuddin Zali Oct 16 '15 at 15:58
  • http://www.howtogeek.com/213795/how-to-enable-intel-vt-x-in-your-computers-bios-or-uefi-firmware/ and https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/5/html/Virtualization/sect-Virtualization-Troubleshooting-Enabling_Intel_VT_and_AMD_V_virtualization_hardware_extensions_in_BIOS.html articles clearly says that. – silverwolf Oct 16 '15 at 16:01
  • yes, the article is correct, but its not only bound to BIOS settings. CPU must have virtualization capability, BIOS must be sets to make the virtualization on, BIOS also a software, vendor can lock the virtualization in it. Check this when Asus do a Vendor locked-in for Virtualization support. – Aizuddin Zali Oct 16 '15 at 16:12
  • @Aizuddin Zali , you are right about vendor's locking of Virtualization but that chip is too old and I think 99.9% of machines now have BIOS with virtualization on/off capability. – silverwolf Oct 16 '15 at 16:23
  • still some vendor still implement that nowadays, my Lenovo G40-45 does not have that privileges even though AMD A6 supporting AMD-V. – Aizuddin Zali Oct 16 '15 at 16:26
