This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot – please use a kernel appropriate for your CPU

It is a strange error that I encountered installing Centos 6.4 64bit into Virtual Box.

The CPU is AMD A8-3870.  8GB Memory

Host OS is Windows 7 64bit.

VirtualBox is 4.3.6, latest version on Jan 15, 2014.

I have no problem to install Centos x86 version into this VirtualBox. Only when I tried to install the 64bit, the error stops me.


The CPU is 64bit. I did enabled the related CPU features in BIOS. I know someone has installation problem of 64bit OS just because of this.

What is the solution of this error?

Calibre released 0.9.15

It has new features.

  • Linux MTP driver: Detect devices that have MTP interfaces even if their USB ids are not known
  • Content server: Allow picking a random book by clicking the ‘Random book’ link on the start page. You can also refresh the random book page to get a new random book
  • E-book viewer: Add an option to hide the toolbars in the viewer window (Preferences->Miscellaneous->Show controls in the viewr preferences). You can unhide them by right clicking in the viewer window.
  • Kobo driver: Speedup initial connect by avoiding unnecessary update of series metadata in some situations.
  • Get Books: Allow the store plugins to be dynamically loaded so that future website changes of a store dont require a calibre update to fix Get Books.
  • Wireless driver: Always replace file when resending a previously sent book to the device, even if the title/author have changed.
  • Add PocketBook Pro 912 driver.
  • When creating/exporting epub and mobi files, add the calibre book identifier as a special field in the book’s metadata. This allows third party tools to identify the book record in calibre to which the file belongs.
  • Wireless driver: Add support for using the book uuid as the filename
  • Remove the experimental tag from the subset fonts feature, since there has been only one reported problem (now fixed) with it in the two months since it was released
