Spinning up the Trilio VM
The Trilio Appliance is delivered as qcow2 image and runs as VM on top of a KVM Hypervisor.
Creating the cloud-init image
The Trilio appliance is utilizing cloud-init to provide the initial network and user configuration.
Cloud-init is reading it's information either from a metadata server or from a provided cd image. Trilio is utilizing the cd image.
Needed tools
To create the cloud-init image it is required to have genisoimage available.
Providing the Metadata
Cloud-init is using two files for it's metadata.
The first file is called meta-data
and contains the information about the network configuration.
Below is an example of this file.
The instance-id has to match the VM name in virsh
The second file is called user-data
and contains little scripts and information to set up for example the user passwords.
Below is an example of this file.
creating the image file
The image is getting created using genisoimage follwing this general command:
genisoimage -output <name>.iso -volid cidata -joliet -rock </path/user-data> </path/meta-data>
An example of this command is shown below.
Spining up the Trilio appliance
