This document discusses booting virtual machines from volumes in OpenStack. It provides an overview of the Cinder block storage system and describes the booting process. It then details three booting methods - booting an instance from an image and attaching a non-bootable volume, booting from a bootable volume, and attaching swap or ephemeral disks. Steps are provided for creating and attaching both bootable and non-bootable volumes.

Content › 1. Overview of Cinder › 2. Booting process of a virtual machine › 3. Booting methods › 4. Demo
1. Overview of cinder › Block Storage allows block devices to be exposed, better performance and integration with storage platform. › OpenStack provides persistent block storage devices in use with Openstack instances. › Block storage system manages, controls the operation of block storage devices in relationship with server. Block storage volumes are integrated with Openstack.

2. BOOTING PROCESS
3. Booting methods › Boot instance from an image and attach a non-bootable volume. › Boot instance from a bootable volume. › Attach a swap or ephemeral disk to an instance.
Non-bootable volume › 1. Create non-bootable volume by cinder. › $ cinder create --display-name NAME SIZE › 2. Boot instance. › $ nova boot --flavor 1 --image IMAGE_ID --nic net-id=NET_ID --block-device source=SOURCE,id=VOLUME_ID,dest=DEST,shutdown=preserve|remote NAME › 3. Attach non-bootable volume to instance. › $ nova volume-attach SERVER_ID VOLUME_ID DEVICE(/dev/vda)
Bootable volume › 1. Create bootable volume from image. › $ cinder create SIZE --image-id IMAGE_ID › 2. Attach volume to a server. › $ nova volume-attach SERVER_ID VOLUME_ID DEVICE(e.g. /dev/vdb) › 3. Create bootable volume from image launch from this volume. › $ nova boot --flavor FLAVOR --block-device source=SOURCE,id=ID,dest=DEST,size=SIZE,shutdown=PRESERVE|REMO VE,bootindex=INDEX NAME
Attach Swap or ephemeral disk › When attaching swap or ephemeral disk, after instance is terminated, they will be deleted. › $ nova boot --flavor FLAVOR --image IMAGE_ID --swap SWAP_SIZE --ephemeral size=SIZE NAME
