Then use rdmsr, ( quick intoduction) to read processor MSR's.įor Intel processors one can check current status by reading IA32_FEATURE_CONTROL (1) from the processor. If not enabled (read fails) load msr by: modprobe msr Read the machine/model specific registers (MSR), ( man msr), using msr-tools VME (Virtual mode extension) # On a specific i386Ĭhecking status - require root privileges One can also check flags from BIOS by dmidecode dmidecode -type 4 | grep -i virt If not found, one are most likely out of luck. Intel check if vmx is found ( VT-x) grep -o "^flags\s*.*\svmx\(\s\|$\)" /proc/cpuinfoĪMD check if svm is found ( AMD-V) grep -o "^flags\s*.*\ssvm\(\s\|$\)" /proc/cpuinfo Also included some information that you know like grep for svm – for completeness sake. Included procedure for both Intel and AMD as if anyone is on either.
