I tried ot make it a single processor host during the import. Now it fails differently.
VirtualBx – Error
VT-x/AMD-V hardware acceleration is not available on your system. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot.
I chose to ignore the error and ‘Continue’
it goes to booting CentOS – and then craps out with the error message on the console:
This kernel requiers an x86-64 CPU, but only detected an i686 CPU.
Unable to boot – please use a kernel appropriate for your CPU.
