Oracle VM virturalbox is a free and open source powerful virtual machine software. The main products of Oracle (Oracle database, Oracle convergence middleware, Oracle business products and Oracle RAC) have passed the certification of Oracle VM, which is also the only virtualization software with Oracle application certification in the industry. There will always be problems in the process of using the product. The author recently re installed the machine, and the following problems occurred when installing the virtual machine on the new machine: as shown in Figure 1

This kernel requires an x86-64 CPU,but only detected an i686 CPU.

Unable to boot – please use a kernel appropriate for your CPU.

After reading a lot of materials, I successfully solved the problem. Now I will share the process of solving the problem with you, so as to help more people
