Are you by chance using nested virtualization of some other virtual machines? If so, it's enough to add "-vmx" at the end of "-cpu host,-hypervisor,kvm=3Doff". If you are not sure of the answer, please check if your /etc/modprobe.conf file, or any file in your /etc/modprobe.d directory, contains the line "options kvm_intel nested=3D1".
