This Kernel requires a x86064 CPU, but only detected an i686

Post by Farzad »

Customer is getting below error when starting Oracle VM VirtualBox for the PeopleSoft Update Manager-PUM.

This Kernel requires a x86064 CPU, but only detected an i686 CPU.
Unable to boot - pleease use a kernel appropriate for your CPU.

The screenshots indicate that virtualization is enabled. Did some research on the processor - it's an opteron 8380, released in 2008, so it's on the older end of the spectrum.

Any help is appreciated.

  • 64-bit guests need hardware-virtualzation enabled in the host's BIOS (VT-x/AMD-V).
  • When creating the 64-bit guest you must select 64-bit variant of the OS.
  • If another virtualization program is running and not "cooperating" you must disable it or uninstall it (see example below).
  • If running Windows as host you must make sure Hyper-V or XP-mode is not enabled on the host.
