 {Project} can connect to the `libvirt` API on the hypervisor to provision hosts and control certain virtualization functions.
+Optional Trusted Platform Module (TPM) support is available for libvirt virtual machines.
 
 Only Virtual Machines created through {Project} can be managed.
 Virtual Machines with other than directory storage pool types are unsupported.
