1. Move to a YAML-based configuration format instead of the original INI-based configuration to facilitate better organization and readability. 2. Modify the daemon to be able to operate in several modes based on configuration flags. Either networking or storage functions can be disabled using the configuration, allowing the PVC system to be used only for hypervisor management if required.

# pvcd cluster configuration file example
|
|
#
|
|
# This configuration file specifies details for this node in PVC. Multiple node
|
|
# blocks can be added but only the one matching the current system nodename will
|
|
# be used by the local daemon. Default values are not supported; the values in
|
|
# this sample configuration are considered defaults and, with adjustment of the
|
|
# nodename section and coordinators list, can be used as-is on a Debian system.
|
|
#
|
|
# Copy this example to /etc/pvc/pvcd.conf and edit to your needs
