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

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

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


I'm lost!


From the error message:

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

And your processor is an i686





So to use KVM you need to upgrade your processor

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

  • @cucuru Your CPU still does not support KVM. You need a new, "modern" cpu if you wish to run KVM. Perhaps if you installed a 64 bit version of Ubuntu, but cpuinfo should show the flags – Panther Aug 10 '15 at 18:04
  • so, I need a new computer??? – cucuru Aug 10 '15 at 18:29
  • A CPU that support KVM, yes. See the links. You need a CPUu with either the vmx or svm flags – Panther Aug 10 '15 at 18:39
  • @cucuru - On the link to your CPU "Intel® Virtualization Technology (VT-x) ‡ No" you need a CPU that has ("yes') to this feature – Panther Aug 10 '15 at 18:56
