Summary

Support Creating EBS boot volumes when boot-time

Release Note

When this is implemented, VM will use auto-created volumes as root and local(defined on flovor 'local_gb'). The 'auto_create_boot_volumes' flag should be True to tragger this logic.

Rationale

With BootFromVolume blueprint, we can use a volume as root like EC2 supports EBS-based volume.

But it needs pre-created and pre-os-installed volumes.

With this blueprint, There's no need the pre-created volume.

Below steps will be added.

1) create volumes using volume-manager on boot time.

2) copy cached OS image into the root volume device.

3) inject ssh key or metadata or files into the root volume device if it needs.

User stories

• Administrator will set 'auto_create_boot_volumes' flag to True.
• User will see instances booted with volumes attached.

Assumptions

For root volume support, the following blueprints are assumed.

• boot from volume
