In the old patchset from March, things used to work like this. rng device probably not needed by SAP at the moment.

Cloud Hypervisor uses a pty as a channel to and from the guest. To allow openstack to display the console output of the VM, the pty must be read. Reading from the pty has proven tricky, as it seems some input needs to be provided and order to get output again. Therefore, we send some null byte to the pty prior to reading. The reading is also done in a loop to receive all available output. On-behalf-of: SAP stefan.kober@sap.com
Currently, the Nova Libvirt driver only enables numa tuning if QEMU/KVM is the hypervisor type. As we have built NUMA support for the Libvirt CHV driver, we now want to enable it in Nova too.
Nova requires some CPU model like host passthrough, host model, or custom. Otherwise, things like NUMA tunings will not be configured correctly later on. Therefore, we use host-passthrough per default for cloud-hypervisor, which is the only mode currently supported.
