[Openstack] Nova adding "-no-kvm" even though the system has KVM enabled

Can anyone think of a reason why Nova (Grizzly) would be starting my VMs with the "-no-kvm' flag even though KVM is fully functional?

VMX is supported

[admin at localhost ~]$ grep vmx /proc/cpuinfo | head -n1
flags           : <snip>vmx<snip>

VT is not disabled in the BIOS

[admin at localhost ~]$ dmesg | grep -i bios
<no results>

The kvm device is there and configured

[admin at localhost ~]$ ls -l /dev/kvm
crw-rw-rw-+ 1 root kvm 10, 232 Oct 14 11:27 /dev/kvm

I'll be happy to provide further information if necessary.
