I've installed KVM 0.9.0 on RHEL6, however, when I try to add kvm_intel module on the fly, I get the following:

[root@ApacheFTP ~]# modprobe kvm ; modprobe kvm_intel
FATAL: Error inserting kvm_intel (/lib/modules/2.6.32-431.el6.x86_64/kernel/arch/x86/kvm/kvm-intel.ko): Operation not supported
[root@ApacheFTP ~]# 

Here is a listing of the cpu for this VM:

[root@ApacheFTP ~]# lscpu

For the hypervisor, I'm using VirtualBox 5.0 and I have hardware virtualization checked for Enable VT-x/AMD-V, so I'm not sure why isn't not loading this module.

I am able to run KVM with no issue at this time.
