Hi All,

I have created a bash script that uses curl and the REST API based on the
docs that I could find.

I have the script working all the way up until the VM-ToBeBackedUp-Disk is
attached to the VM-RunningTheBackupScript with the mention of the Snapshot.

Example:

<disk_attachment>
    <disk id="33b533f8-13b1-4cc1-8091-31b07913b32a">
       <snapshot id="34709147-4b0c-4684-b3d9-f4892873f36f²/>
    </disk>
    <bootable>false</bootable>
    <interface>virtio</interface>
</disk_attachment>

kattachments/

The above results in an attached disk to my VM-RunningTheBackupScript.

The question I have is how to I image that disk from the
VM-RunningTheBackupScript?

The VM-RunningTheBackupScript is running Debian8 and that VM cannot see the
attached disk as it is Inactive.

I have reviewed many of the older scripts out there and it looks trivial,
however everything I have tried has no joy ;/

If anyone on the list knows of the required magic, please advise ;)

* If I have to go to using python etc, I will, but trying to avoid it if
possible. Either way, I need some examples of how to proceed.
