openstack-manuals: Update nova CLI information for boot from volume

[Diane Fleming]

Update nova CLI information for boot from volume:

The page boot from volume in the nova CLI is an OpenStack doc, but it was based on older DevStack. The command that would work on OpenStack clouds with the policy that enables this is:

nova --debug boot --flavor 4 --image 23b564c9-c3e6-49f9-bc68-86c7a9ab5018 --block-device-mapping vda=6efa7008-ada7-4438-9033-efba4aa5cb06 ex-vol-bfv

When you run it with —debug you see all the API calls. I think the one that does the boot is:

REQ: curl -i https://dfw.servers.api.rackspacecloud.com/v2/525722/os-volumes_boot -X POST -H "X-Auth-Project-Id: admin" -H "User-Agent: python-novaclient" -H "Content-Type: application/json" -H "Accept: application/json" -H "X-Auth-Token: c7d4860ec51d4479a226e7d3ed72573c" -d '{"server": {"name": "ex-vol-bfv", "imageRef": "23b564c9-c3e6-49f9-bc68-86c7a9ab5018", "block_device_mapping": [{"volume_id": "6efa7008-ada7-4438-9033-efba4aa5cb06", "device_name": "vda"}], "flavorRef": "4", "max_count": 1, "min_count": 1, "networks": [{"uuid": "00000000-0000-0000-0000-000000000000"}, {"uuid": "11111111-1111-1111-1111-111111111111"}]}}'

However on the Rackspace Cloud you get a 403 error with an explanation of "Policy doesn't allow compute:create:attach_volume to be performed."

We do have a doc bug to document the change in use of block_device_mapping, https://bugs.launchpad.net/openstack-api-site/+bug/1087051.
