Hi, I was trying to install Ubuntu as a guest operating system in my setup which has Intel i3 Windows 7 and 4.3.4r91027 version of the virtual machine installed in it. After doing so when I tried to boot Ubuntu it complained that it didn’t have an x64 CPU. But on checking the settings everything was enabled already. What is the thing that I am missing?
Learn To Install Ubuntu(64 Bit) In Virtualbox 64 Bit Windows 7 As Guest OS In Your Setup
Hi, In order to enable guests of 64 bits, the following steps can be taken into account.
Step1: The CPU that is being used must have the 64-bit capability and must support either Intel or AMD virtualization technologies. So first the capabilities of the CPU has to be checked.
Step 2: VT-x/AMD-v has to be enabled in the host PC BIOS and booted into the BIOS screen. After doing so the option ”Enable Virtualisation Technology” is enabled in the security category and the host PC is rebooted after making the changes.
Step3: Before creating a VM it is made sure that no other host apps are already using VT-x/AMD-v.Another thing that is to be made sure before creating a VM is that the 64-bit version of the guest OS template is chosen (VM settings->General->Basic->Version)i.e. choose “Ubuntu(64 bit) “and not “Ubuntu”.
Choosing the correct template is important here or else it may show errors while booting.
