nova-manage DB analysis
Analysis of the direct database usage by nova-manage. A place to keep information about where nova-manage is directly manipulating the database and extra Nova APIs that we will need in order in order to stop doing this. The blueprint for this work is here https://blueprints.launchpad.net/nova/+spec/apis-for-nova-manage
Changes needed by nova-manage command
| Command | Subcommand | REST API | nova CLI |
| account/project | quota | Quota Sets extension implements required functionality | Already supported |
| scrub | Network and Security extensions have required support | Need to get list of networks for a tenant, disassociate them and then destroy the security groups. The nova command currently allows people to do the secgroup changes but not the network changes | |
| agent | create | No support | No support |
| db | sync | No support | No support |
| fixed | list | Need Fixed IP extension | No nova support |
| flavor/instance_type | create | Can be implemented using core Nova API and Flavor management extension | Already implemented in nova client |
| set_key | API exists in flavorextraspecs.py but not documented at api.openstack.org | Need to add support to nova client | |
| floating | create | Need to add REST API for bulk creation of floating ips and to list | Need to add support to nova client |
| host | list | Host extensions API can list physical hosts, but does not show availability zones | Exists in nova client (without availability zone display) |
| logs | No API required. No DB access | ||
| network | create | Network API extension exists but needs extra options for creation (cf. API vs ""nova-manage network create"" options) | Need nova client support |
| list | Network API extension exists but needs to return more information (eg DNS2, vlan) | Need nova client support | |
| delete | delete by id supported by Network API, but not deletion by fixed-range | Need nova client support | |
| modify | Can add network to project using Network API but need support to add network to host. Similarly for disassociate. | Need nova client support | |
| service | list | No REST API exist for list/enable/disable/describe nova services | Need nova client support |
| shell | No API support required. No db access | ||
| sm | flavor_list | Need a storage manager extension API | Need nova client support |
| version | No API support required. No db access | ||
| vm | list | Core API support | Support already in nova client |
| volume | reattach | Volume extension API does not have reattach, but does have attach | |
| vpn | change | Need to add to cloudpipe API to change ip and port for vpn | Need nova interface |
