This daemon exposes the whole {pve} API on 127.0.0.1:85. It runs as
root and has permission to do all privileged operations.

Note
|
The daemon listens to a local address only, so you cannot access
it from outside. The pveproxy daemon exposes the API to the outside
world.

pvedaemon delegates handling of incoming requests to worker processes. By
default, pvedaemon spawns 3 worker processes, which is sufficient for most
workloads. For automation-heavy workloads that issue a huge volume of API
requests and that experience slow request handling or timeouts, the number of
worker processes can be increased by setting MAX_WORKERS in
/etc/default/pvedaemon, for example:
MAX_WORKERS=5
Note that a higher number of worker processes may result in higher CPU usage. The number of worker processes must be greater than 0 and smaller than 128.
The same setting exists for pveproxy.
