[Nathanaël Blanchet]

Hello Victor,

I have some questions about your script

  * Backup step is okay, and I get a usable qcow2 image of the snapshot
    vm in the backup vm. It seems to be compliant with the official
    backup API, except on the step 2.

 1. /Take a snapshot of the virtual machine to be backed up - (existing
    oVirt REST API operation)/
 2. /Back up the virtual machine configuration at the time of the
    snapshot (the disk configuration can be backed up as well if needed)
    - (added capability to oVirt as part of the Backup API)/

I can't see any vm configuration anywhere but only the qcow2 disk itself

 1. /Attach the disk snapshots that were created in (1) to the virtual
    appliance for data backup - (added capability to oVirt as part of
    the Backup API)/
 2. /
    /
 3. /Detach the disk snapshots that were attached in (4) from the
    virtual appliance - (added capability to oVirt as part of the Backup
    API)/

An other case is when the vm to backup has more than one disk. After I 
tested it, I found that only one qcow2 disk is saved on the backup vm. 
This is really a matter when the original vm has many disks part of lvm, 
it makes the vm restoration unusable.

  * About vm restoration, it seems that you are using the upload_disk
    api, so the disk is uploaded to the pre-defined storage domain, so
    it is not a real vm restoration.

Do you plan to backup and restore a full VM (disks + vm definition) in a 
next release?
