[Kimchi-devel] [PATCH 3/9 - v6] UI - Implement multiple disks support in Template edit window

Wed Dec 2 15:59:20 UTC 2015


- This patch implements necessary changes in frontend to allow
  users to edit and add/remove extra disks to a chosen Template.
- This patch also refactor the UI code in order to avoid lots
  of backend calls, improving performance.
- Template disks data saved in objectstore have new fields:
  * 'size' is always recorded, even for ISCSI/SCSI types;
  * 'storagepool type' is always recorded;
  * example:
      "disks":[
        { "index": 0,
          "format": "raw",
          "volume": "unit:0:0:2",
          "pool": {
              "name": "/plugins/kimchi/storagepools/test-iscsi",
              "type": "iscsi"
              }
          "size": 7
        },
        { "index": 1,
          "format": "qcow2",
          "pool": {
              "name": "/plugins/kimchi/storagepools/default",
              "type": "dir"
              }
          "size": 3
        }
      ]
