在Windows的VirtualBox上运行的Ubuntu上启用kvm [英] Enable kvm on Ubuntu running on VirtualBox on Windows

问题描述

我有一台装有Intel CPU的Windows机器(在启动菜单上启用了VMX).我正在使用VirtualBox在其上运行Ubuntu Guest.我正在其上运行qemu以使用kvm(-enable-kvm选项)运行另一个Guest OS.

在尝试插入kvm-intel模块时出现以下错误:

FATAL: Error inserting kvm_intel (/lib/modules/2.6.20-ARCH/kernel/drivers/kvm/kvm-intel.ko): Operation not supported

我已经在来宾操作系统中检查了vmx标志，但我也没有看到

$ grep vmx /proc/cpuinfo
$

反正有没有在来宾Ubuntu操作系统中启用kvm支持，以便我可以在Ubuntu来宾计算机顶部运行启用了kvm的qemu?

VMX非功能不是通过了由̶v̶i̶r̶t̶u̶a̶l̶b̶o̶x̶.̶并且看起来VirtualBox的团队本身鸵鸟政策看到，它需要实现随时随地̶s̶o̶o̶n̶.̶ ̶S̶e̶e̶̶t̶h̶e̶̶c̶o̶m̶m̶e̶n̶t̶s̶̶a̶t̶̶h̶t̶t̶p̶s̶:̶/̶/̶w̶w̶w̶w̶.̶v̶i̶r̶t̶u̶a̶l̶b̶o̶x̶/̶̶2̶0̶

从6.0版开始，现在支持嵌套虚拟化(当前仅适用于AMD cpus！)

I have a Windows machine with an Intel CPU (VMX Enabled on boot menu). I am running Ubuntu Guest on top of it using VirtualBox. I am running qemu on top of it to run another Guest OS, using kvm (the -enable-kvm option).

I get the following error on trying to insert kvm-intel module:

FATAL: Error inserting kvm_intel (/lib/modules/2.6.20-ARCH/kernel/drivers/kvm/kvm-intel.ko): Operation not supported

I have checked for vmx flag in the guest OS and I dont see that either

$ grep vmx /proc/cpuinfo
$

Is there anyway to enable kvm support in the guest Ubuntu operating system so that I can run kvm-enabled qemu on top of the Ubuntu guest machine?

Since version 6.0, nested virtualization is now supported (currently for AMD cpus only!)
