os-hypervisors api can not list the uuid of the specified VMM

[mylq]

os-hypervisors api just cann't list the host's uuid.
we could find uuid field in nova.compute.

but the List Hypervisors Details api in https://developer.openstack.org/api-ref/compute/ couldn't list the uuid.
Here is the code of nova/api/openstack/compute/hypervisors.py
 60 for field in ('vcpus', 'memory_mb', 'local_gb', 'vcpus_used',
 61 'memory_mb_used', 'local_gb_used',
 62 'hypervisor_type', 'hypervisor_version',
 63 'free_ram_mb', 'free_disk_gb', 'current_workload',
 64 'running_vms', 'disk_available_least', 'host_ip'):
 65 hyp_dict[field] = getattr(hypervisor, field)

Thanks for your bug report. Unforutunatly, it doesn't really correspond to a notion of either a regression or a technical issue, but rather a missing feature.

We have a specific process for approving feature requests thru Launchpad Blueprints and what we call 'specs', ie. formalized textual RFEs describing the problem description and the proposal.

FWIW, what you're asking for is actually already approved for our Pike timeframe :
https://blueprints.launchpad.net/nova/+spec/service-hyper-uuid-in-api
http://specs.openstack.org/openstack/nova-specs/specs/pike/approved/service-hyper-uuid-in-api.html

I'd suggest you helping by at least reviewing the current series where some patches have already merged https://review.openstack.org/#/q/topic:bp/service-hyper-uuid-in-api,n,z
