3	Restart Cinder and Glance services
4	Upload a Glance Image
5	Boot from Cinder
6	Verify functionality

Table 5.2: Checklist of Steps for Enhanced Instance Creation

Configure internal tenant settings in cinder.conf

Obtain the cinder_internal_tenant_project_id

$ openstack service list
+----------------------------------+-------------+----------------+
| ID                               | Name        | Type           |

+----------------------------------+-------------+----------------+

Edit cinder.conf to contain the following entry in the DEFAULT stanza

[DEFAULT]
...
cinder_internal_tenant_project_id=6763e676132f4aaabb68cc1517b18d38
...

Obtain the cinder_internal_tenant_user_id

$ openstack user list
+----------------------------------+----------+
| ID                               | Name     |
+----------------------------------+----------+
| 6275bf0ad03743949f7d8752464e30e5 | admin    |
+----------------------------------+----------+

Edit cinder.conf to contain the following entry in the DEFAULT stanza

[DEFAULT]
...
cinder_internal_tenant_user_id=a05232baaeda49b589b11a3198efb054
...

Configure Image-Volume cache settings in cinder.conf

[DEFAULT]
...
image_volume_cache_enabled = True
...

Restart Cinder services

$ systemctl restart openstack-cinder-{api,scheduler,volume}

Upload a Glance image

The following command uses an image that is publicly available. Please use the image you prefer and replace the URL accordingly.

$ wget https://s3-us-west-2.amazonaws.com/testdrive-bucket/images/trusty-server-cloudimg-amd64-disk1-nfs-edit.img | glance image-create --name=ubuntu-nfs-image --container-format=bare --disk-format=qcow2 --file=trusty-server-cloudimg-amd64-disk1-nfs-edit.img –-progress

Boot from Cinder

$ nova boot --flavor m1.medium --key-name openstack_key --nic net-id=replace-with-neutron-net-id --block-device source=image,id=replace-with-glance-image-id,dest=volume,shutdown=preserve,bootindex=0,size=5  ubuntu-vm

Verify functionality

Please open /var/log/cinder/volume.log and look for a message similar to the following to confirm that the image-volume was cached successfully:

...
