module: proxmox
short_description: Management of instances in Proxmox VE cluster
description:
  - Allows you to create/delete/stop instances in Proxmox VE cluster.
  - The module automatically detects containerization type (lxc for PVE 4, openvz for older).
  - Since community.general 4.0.0 on, there are no more default values.

  disk:
    description:
      - This option was previously described as "hard disk size in GB for instance" however several formats describing
        a lxc mount are permitted.
      - Older versions of Proxmox will accept a numeric value for size using the O(storage) parameter to automatically
        choose which storage to allocate from, however new versions enforce the C(<STORAGE>:<SIZE>) syntax.
      - "Additional options are available by using some combination of the following key-value pairs as a
        comma-delimited list C([volume=]<volume> [,acl=<1|0>] [,mountoptions=<opt[;opt...]>] [,quota=<1|0>]
        [,replicate=<1|0>] [,ro=<1|0>] [,shared=<1|0>] [,size=<DiskSize>])."
