virtualization type in /etc/nova/nova.conf

Hi all,

I'm following the official documentation to install openstack newton on centos 7, however, when configuring virt_type in /etc/nova/nova.conf, the documentation says:

Determine whether your compute node supports hardware acceleration for virtual machines:

$ egrep -c '(vmx|svm)' /proc/cpuinfo If this command returns a value of one or greater, your compute node supports hardware acceleration which typically requires no additional configuration.

If this command returns a value of zero, your compute node does not support hardware acceleration and you must configure libvirt to use QEMU instead of KVM.

What I can't get is how if my node doesn't support hardware acceleration then I'm supposed to use qemu instead of kvm despite the fact that kvm is accelerating agent that is used alongside qemu?
