#
# Added support for Proxmox VE 4.x
# Added support for using the Notes field of a VM to define groups and variables:
# A well-formatted JSON object in the Notes field will be added to the _meta
# section for that VM. In addition, the "groups" key of this JSON object may be
# used to specify group membership:
#
# { "groups": ["utility", "databases"], "a": false, "b": true }
