Identifying Virtualization System Properties

From Crashcourse Wiki

What you can do in terms of virtualization depends on your running kernel, underlying hardware and possible virtualization extensions, so it's worth taking a minute or two and checking your system.

Do you have a 32- or 64-bit CPU?

$ grep -w lm /proc/cpuinfo      ("lm" stands for "long mode" or 64-bit)

The wordsize of your current kernel, given that you can be running a 32-bit kernel on a 64-bit CPU:

$ uname -r
...i686          (32-bit)
...x86_64        (64-bit)

If it's a 32-bit system, do you have PAE extensions?

$ grep -w pae /proc/cpuinfo

And, finally, do you have either the Intel or AMD virtualization extensions?

$ grep -w vmx /proc/cpuinfo                     (Intel VT support)
$ grep -w svm /proc/cpuinfo                     (AMD AMD-V support)

Am I missing anything, or is there a better way to check any of the above?
