[Bug 1201092] Re: Cannot load kvm_amd module - (says disabled by bios)



I wasn't actually saying "bug in the bios" - I was suggesting the
feature was turned off in the bios.  Could you please boot into the bios
(or EFI) and check the 'virtualization' settings?  Or if you've already
done that, and it was enabled, please let us know - Thanks!

Bug description:
  - Firt of all I would like to mention that this bug as been also raised for Fedora 18.
  Here is the link: https://bugzilla.redhat.com/show_bug.cgi?id=978608

  - I am running Ubuntu Raring (with the kernel 3.8.0-27-generic), but
  NOTE that I've also tried the new kernel 3.10 from Ubuntu Saucy.

  - It happens with the following CPU: AMD E-350D

  - The kvm-ok executable says that the system is capable of running
  KVM, but it also says the it's disabled in the BIOS.

  - This is the out put of kvm-ok:
  # kvm-ok
  INFO: /dev/kvm does not exist
  HINT:   sudo modprobe kvm_amd
  INFO: Your CPU supports KVM extensions
  INFO: KVM (svm) 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

  - This is what modprobe kvm-amd says:
  # modprobe kvm-amd
  ERROR: could not insert 'kvm_amd': Operation not supported
  root@yasna:~# dmesg |tail -n1
