I have Dell XPS 13 9350 laptop and I needed to install few virtual machine to it using
Oracle VirtualBox software but when I tried to install example Windows 10 or Kali Linux I alwas got error message
“VT-x/AMD-V hardware acceleration has been enabled, but is not operational. Your 64-bit guest will fail
to detect a 64-bit CPU and will not be able to boot.
Please ensure that you have enabled VT-x/AMD-V properly in the BIOS of your host computer.”
To fix this you have to boot your laptop and go to bios and remove check mark from “Enable CPU XD Support”:
Security -> CPU XD Support -> Enable CPU XD Support
“This option enables or disables the Execute Disable Mode of the Processor. The operating system can use this feature to hinder software that exploits buffer overflows”
After that Windows 10, Kali Linux and other virtual machines on Oracle VM VirtualBox worked perfectly.
Comment and let me know if this worked for you. Especially with different operating systems and so on.
