Does your cpu supports virtualization?

This is how you check it

egrep '(vmx|svm)' --color=always /proc/cpuinfo

If you get vmx (intel) or svm – (amd) it does.

XEN kernel? try

cat /sys/hypervisor/properties/capabilities

 

My PowerEdge doesn’t?! f*ck!

 

INTEL:

VT-x, shows in /proc/cpuinfo as the vmx flag. (grep vmx /proc/cpuinfo)

AKA Vanderpool

See Wikipedia’s article on x86 virtualization, for a list of processors that include it.

AMD:

AMD-V, shows in /proc/cpuinfo as the svm flag. (grep svm /proc/cpuinfo)

AKA Pacifica, AKA AMD Virtualization
