1 How will check my CPU support Hyper-V or VT Enabled Find out processor model CPU-Z is a utility to shows your processor information Using command to check this from windows wmic:root\cli>cpu list AddressWidth Architecture Availability Caption ConfigManagerErrorCode ConfigManagerUserConfig CpuStatus CreationClassName CurrentClockSpeed CurrentVoltage DataWidth Description DeviceID ErrorCleared ErrorDescription ExtClock Family InstallDate L2CacheSize L2CacheSpeed LastErrorCode Level LoadPercentage Manufacturer MaxClockSpeed Name OtherFamilyDescription PNPDeviceID PowerManagementCapabilities PowerManagementSupported ProcessorId ProcessorType Revision Role SocketDesignation Status StatusInfo Stepping SystemCreationClassName SystemName UniqueId UpgradeMethod Version VoltageCaps x86 Family 6 Model 23 Stepping 10 1 Win32_Processor x86 Family 6 Model 23 Stepping 10 CPU GenuineIntel 1999 Intel Pentium III Xeon processor FALSE BFEBFBFF A CPU Socket 479 OK 3 10 Win32_ComputerSystem SAJITH 9 Model 7, Stepping x86 Family 6 Model 23 Stepping 10 1 Win32_Processor x86 Family 6 Model 23 Stepping 10 CPU GenuineIntel 1999 Intel Pentium III Xeon processor FALSE BFEBFBFF A CPU Socket 479 OK 3 10 Win32_ComputerSystem SAJITH 9 Model 7, Stepping 10 wmic:root\cli>cpu get caption Caption x86 Family 6 Model 23 Stepping 10 x86 Family 6 Model 23 Stepping 10 wmic:root\cli>cpu get /format:list AddressWidth=32 Architecture=0 Availability=3 Caption=x86 Family 6 Model 23 Stepping 10 ConfigManagerErrorCode= ConfigManagerUserConfig= CpuStatus=1 CreationClassName=Win32_Processor CurrentClockSpeed=1199 CurrentVoltage=16 DataWidth=32 Description=x86 Family 6 Model 23 Stepping 10

The flags to look out for are: vmx Intel VT-x, basic virtualization svm AMD SVM, basic virtualization ept Extended Page Tables, an Intel feature to make emulation of guest page tables faster. vpid VPID, an Intel feature to make expensive TLB flushes unnecessary when context switching between guests. npt AMD Nested Page Tables, similar to EPT. tpr_shadow and flexpriority Intel feature that reduces calls into the hypervisor when accessing the Task Priority Register, which helps when running certain types of SMP guests. vnmi Intel Virtual NMI feature which helps with certain sorts of interrupt events in guests. or by kernel messages by running the command: dmesg less messages to look out for are: kvm: no hardware support

4 and kvm: disabled by bios or install utility $ sudo apt-get install cpu-checker and then $ sudo kvm-ok messages will like INFO: /dev/kvm exists KVM acceleration can be used INFO: /dev/kvm does not exist HINT: sudo modprobe kvm_intel INFO: Your CPU supports KVM extensions INFO: KVM (vmx) is disabled by your BIOS HINT: Enter your BIOS setup and enable Virtualization Technology (VT), and then hard poweroff/poweron your system KVM acceleration can NOT be used Loading the KVM module Try to load the KVM module by hand. To load KVM on an Intel processor: modprobe kvm_intel To load KVM on an AMD processor: modprobe kvm_amd Check dmesg output and Check lsmod to see if the modules were loaded.

5 INTEL Download the utility from /pidenu36.msi&lang=eng&dwnldid=7838

6 AMD 4d9dc646342f&ItemID=177 Message looks like Another tool from Microsoft which will work on both Intel and AMD processor Windows OS computers. download and extract to directory D:\>havdetectiontool.exe /x D:\havc\sources\i386>havtool.exe /?
