关于在ubuntu系统上安装了virtualbox的问题

Question

各位好，我在我的ubuntu16.04中安装了virtualbox5.2，想在里边单独开一个新的ubuntu虚拟机。但发现了问题，选择虚拟机的时候全是32位，没有64位，我从网上找了好多教程，全是windows下如何设置64位。所以求助在ubuntu下如何设置。谢谢

一般来说，用virtualBox安装64bit的虚拟机：(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.

需要64位的cpu(带硬件虚拟化支持)和64位的操作系统

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.

必须运行64位的VirtualBox，才可以装32位或64位的虚拟机；32位的VirtualBox只能装32位的虚拟机，而不论硬件是否支持64位

3.You must enable hardware virtualization; software virtualization is not supported for 64-bit VMs.

你必须允许硬件虚拟化；软件虚拟化是不支持64位虚拟机

So, running 64-bit guest require:
所以，运行64位的虚拟机需要
– hardware virtualization support in your CPU (called VT-x by Intel and AMD-V by AMD)
-cpu支持硬件虚拟化(intel的叫VT-x，amd的叫AMD-V)(下面的url可以查询你的cpu是否支持)

– you need to make sure it is not turned off by your BIOS (steps depends on your motherboard)
-确定该功能(硬件虚拟化)没有被BIOS关闭(步骤取决于主板)

– make sure it is enabled in virtual box settings of your machine (Settings –> Advanced –> check Enable VX-t/AMD-V)
-确定virtualBox可以在你的机器上设置(设置-》高级-》启用VX-t/AMD-v)
