问题描述
一般来说,如何确定一台 PC 是否支持硬件虚拟化?我使用 VirtualPC 来设置并行测试环境,我会享受一些速度提升.

另外检查,http://en.wikipedia.org/wiki/X86_virtualization>
另外,我知道它适用于 XEN,但所有需要硬件支持的 VM 的说明都是相同的.http://wiki.xensource.com/xenwiki/HVM_Compatible_Processors
我无法在工作中尝试它,但我确信它可以识别您是否获得了 Intel VT 或 AMD-V 指令.Intel 将有一个vmx"指令,而 AMD 将有一个svm".
在 linux 上你可以查看/proc/cpuinfo, "egrep '(vmx|svm)'/proc/cpuinfo"
How, in general, does one determine if a PC supports hardware virtualization? I use VirtualPC to set up parallel test environments and I'd enjoy a bit of a speed boost.

Edit: Additional, I know it's for XEN but the instructions are the same for all VMs that want hardware support. http://wiki.xensource.com/xenwiki/HVM_Compatible_Processors
I can't try it from work, but I'm sure it can identify whether you've got the Intel VT or AMD-V instructions. Intel will have a "vmx" instruction and AMD will have a "svm".
On linux you can check /proc/cpuinfo, "egrep '(vmx|svm)' /proc/cpuinfo"
