The /os-hypervisors/detail API endpoint was experiencing significant performance issues in environments with many compute nodes when using microversion 2.88 or higher, as it made sequential RPC calls to gather uptime information from each compute node. This change optimizes uptime retrieval by: * Adding uptime to periodic resource updates sent by nova-compute to the database, eliminating synchronous RPC calls during API requests * Restricting RPC-based uptime retrieval to hypervisor types that support it (libvirt and z/VM), avoiding unnecessary calls that would always fail * Preferring cached database uptime data over RPC calls when available Closes-Bug: #2122036 Assisted-By: Claude <noreply@anthropic.com> Change-Id: I5723320f578192f7e0beead7d5df5d7e47d54d2b Co-Authored-By: Sylvain Bauza <sbauza@redhat.com> Signed-off-by: Sean Mooney <work@seanmooney.info>

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
