[pve-devel] [PATCH manager 02/12] PVE/API2/Cluster: add Hardware mapping list api call

Dominik Csapak d.csapak at proxmox.com
Tue Jul 19 13:46:29 CEST 2022


this is a cluster wide api call that returns the list of mappings
in a manner that is easy to consume by the ui (as a tree)

it also automatically includes the validity of mappings on the node
where it is called.

for a consumer of this api call to get a complete picture, it is
necessary to do an api call for each node
