Installing kvm /dev/kvm missing

28,047

From the error message:

INFO: Your CPU does not support KVM extensions
KVM acceleration can NOT be used

And your processor is an i686

See:

http://www.linux-kvm.org/page/Processor_support

and

http://www.linux-kvm.org/page/FAQ#Are_64bits_processors_supported_under_KVM.3F

So to use KVM you need to upgrade your processor

You can use Virtualbox and qemu, but they will be slower then KVM

    I'm trying to install kvm extensions in my computer.

    I'm following this guide

    KVM installation

    KVM is not available in my machine and I have a 32 bits one.

    rocio@rocio-laptop:~$ sudo /usr/sbin/kvm-ok
      INFO: Your CPU does not support KVM extensions
      KVM acceleration can NOT be used
    rocio@rocio-laptop:~$ uname -m
       i686
    

    Everything seems to be ok until the verifying

    rocio@rocio-laptop:~$ ls -l /dev/kvm
      ls: no se puede acceder a /dev/kvm: No existe el archivo o el directo
    

    that means in spanish the file or folder doesnt exist.

    Where is the problem?

    I add some information after the bodhi.zazen's answer.

    I have 2 processor:

    rocio@rocio-laptop:~$ cat /proc/cpuinfo
         processor  : 0
         vendor_id  : GenuineIntel
         cpu family : 6
         model      : 23
         model name : Intel(R) Core(TM)2 Duo CPU     T6400  @ 2.00GHz
    

    But none Intel or AMD:

    rocio@rocio-laptop:~$ grep vmx /proc/cpuinfo
    rocio@rocio-laptop:~$ grep svm /proc/cpuinfo
    rocio@rocio-laptop:
    

    Also, in Intel website, it seems to be a 64 bits processor

    I'm lost!

    A CPU that support KVM, yes. See the links. You need a CPUu with either the vmx or svm flags

    @cucuru - On the link to your CPU "Intel® Virtualization Technology (VT-x) ‡ No" you need a CPU that has ("yes') to this feature
