@returntrip , I managed to test this today based on @DaanHoogland
recommendation and here is how you make nested cloudstack plugin to work
- First generate API/Secret Keys of the cloudstack that is hosting your nested
cloudstack deployment
- Then use the following information to confiugre out-of-band management for
the compute hosts inside your nested cloudstack environment
- Address: http://x.x.x.x:8080/client/api (where x.x.x.x is the ip of the
management server of the cloudstack that is hosting your nested cloudstack)
- Port: c4783e16-7898-475e-a073-d8ff6257e5a6 (where
c4783e16-7898-475e-a073-d8ff6257e5a6 is the uuid of the instances that is
created on the cloudstack that is hosting your nested cloudstack)
- Username: api key you previously generated
- Password: the api secret you previously generated
- Driver: nestedcloudstack
- Then you can test if it is working by issuing out-of-band management power
action
- If you are having trouble you can tail the management server log and you will
find some ERROR there if it is not working, for example when i first tried to
use username and password instead of api credential i got the following error
logged
```bash
