This is how you check it
egrep '(vmx|svm)' --color=always /proc/cpuinfo
If you get vmx (intel) or svm – (amd) it does.
root@digitalwhores:/home# grep --color vmx /proc/cpuinfo
flags : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pse36 clflush mmx fxsr sse sse2 syscall nx lm rep_good nopl pni vmx cx16 popcnt hypervisor lahf_lm
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
