Installing Ubuntu in Virtual Machine( VMWare/VirtualBox):īefore getting started, let me first introduce: What is a virtual machine, Which is the best VM Software, and Which VM Software should choose for installing R.O.S. 3 Installing Ubuntu in real PC using USB bootġ.Installing Ubuntu in Virtual Machine( VMWare/VirtualBox): Virtualization Technology (VT) enables a CPU to act as if you have several independent computers, to enable several operating systems to run at the same time on the same machine. What is Virtualization Technology anyway ? To be able to run a 64-bit OS in Virtualbox we have to make sure the virtual machine’s architecture is set to 64-bit too. Note if you are trying to run a 32bit system over a 64bit CPU I should work fine, but the error comes when we try to install 64bit over 32bit If you are trying to install a 32bit guest system then chose 32bit and if you are trying to install 64-bit guest system chose 64-bit. In this case, the problem may be in your virtual machine settingsĬheck your virtual machine configuration and make sure you chose the right CPU type, To fix that try to run a 32bit system just like your host system is 32-bitīut if you still want to run a 64bit guest over a 32bit host, you can do that by enabling Virtualization option or Vtx/X option.Ĭase three but what if you tried all of that and still getting the same error ( This kernel requires an x86-64 CPU ) Enable Intel Virtualization Technology (also known as Intel VT) or AMD-V depending on the brand of the processorĬase tow on another case your host operating system is 32-bit while the system you are trying to run is 64-bit.Open the Processor submenu The processor settings menu may be in the Chipset, Advanced CPU Configuration or Northbridge.Power on your computer and open the BIOS by pressing the delete key or F1 key or F2 or Alt and F4 keys it depend on the system you have.
Unable to boot – please use a kernel appropriate for your CPU “.Ĭase one There is many case you are receiving this message for but the most common one can be fixed from your bios settings on intel CPU you have to enable ” Intel Virtualization Technology ” and on AMD CPU you have to enable “AMD V” this will simply fix this error
Trying to install kali Linux or Ubuntu on Oracle VirtualBox or VMware?īut when running the virtual machine you got this message ” This kernel requires an x86-64 CPU, but only detected an i686 CPU. This kernel requires an x86-64 cpu, but only detected an i686 CPU.
