Comment 35 for bug 1201092

I confirm that this issue arises even with kernels 3.8.0-27 and 3.10 (tryied on Ubuntu): dmesg shows the message "kvm: disabled by bios"
I don't know if Red Hat has the 'kvm-ok' executable, BTW in Ubuntu it says that the machine is capable of running KVM, but KVM is disable. This is the output:

# 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
