This is a feature request, not a bug and dmi information encoded in
libvirt vms is both configurable and non portable across nova compute
virt drivers.

i do not agree that https://bugs.launchpad.net/ubuntu/+source/cloud-
init/+bug/2069607 is a cve but  i am very reluctant to continue to
expand this undocumented internal implementation detail of one of nova
virt driver.

if we considut to support this interface at all we likely shoudl remove
the package version info form teh dmi info because that was previously
cosndierd a secrity weakness.

even if we were to do this for the libvirt driver this does not fix the regresion in cloud int for ironic and other virt driver like vmware or 
zvm so i think the cloud-init team shoudl recondier there approch to https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/2069607

Title:
  identify openstack kvm platform on arm64

Status in cloud-init:
  Expired
Status in OpenStack Compute (nova):
  Opinion

Bug description:
  On i386 and amd64, openstack puts 'OpenStack Nova', into the dmi platform
  information.  OpenStack using kvm on arm64, does not identify itself to the
  guest in any way.

  The result is that OpenStack nodes will not attempt to reach the metadata
  service and will be unusable.

  We need two things
   a.) change openstack to provide that information through libvirt on arm.
   b.) fix qemu bug 1662345 that prevents the information from getting to the guest.
