Hello everyone, I have installed virtualbox5.2, in my ubuntu16.04 and want to open a new ubuntu virtual machine in it. But found the problem, when choosing a virtual machine is all 32-bit, not 64-bit, I found a lot of tutorials from the Internet, all on how to set 64-bit under windows. So how to set up help under ubuntu. Thank you
generally speaking, install the virtual machine of 64bit with virtualBox: ( http://forums.virtualbox.org/.:
1.You need a 64-bit processor with hardware virtualization support (see User Manual chapter 1.2, Software vs. hardware virtualization (VT-x and AMD-V), page 10) and a 64-bit host operating system.
requires 64-bit cpu (with hardware virtualization support) and 64-bit operating system< hr >
2.You must run a 64-bit version of VirtualBox on that OS (Windows Vista, Linux or OpenSolaris). This can then run both 32-bit and 64-bit VMs; a 32-bit VirtualBox can only run 32-bit VMs, regardless of the hardware.
you must run 64-bit VirtualBox, to install 32-bit or 64-bit virtual machines; 32-bit VirtualBox can only install 32-bit virtual machines, regardless of whether the hardware supports 64-bit< hr >
3.You must enable hardware virtualization; software virtualization is not supported for 64-bit VMs.
you must allow hardware virtualization; software virtualization does not support 64-bit virtual machines< hr >
So, running 64-bit guest require:
so running 64-bit virtual machines requires
-hardware virtualization support in your CPU (called VT-x by Intel and AMD-V by AMD)
-cpu to support hardware virtualization (the intel is called VT-x,amd called AMD-V) (the following url can check whether your cpu supports it)
-you need to make sure it is not turned off by your BIOS (steps depends on your motherboard)
-make sure that the feature (hardware virtualization) is not turned off by BIOS (the steps depend on the motherboard)
-make sure it is enabled in virtual box settings of your machine (Settings-> Advanced-> check Enable VX-t/AMD-V)
-make sure virtualBox can be set on your machine (set-"Advanced -" enable VX-t/AMD-v)
