Ronelle Landy commented on DTACLOUD-452:
----------------------------------------
Thanks for the comments above, Dies.
So I saw your additions to check that the instance was running (within the
snapshotting section) but forgot about the changes to actually start the
instance, added way above that :
+ res = get(INSTANCES+"/"+@@my_instance_id)
+ attempts += 1
+ state = (res.xml/'instance/state').text
+ if state == "STOPPED"
+ start_res = post(INSTANCES+"/"+@@my_instance_id+"/start", "")
This essential difference is that RHEVM instances are created in a stopped
state - which was the state need to test the 'create_image' functionality.
Noting now that the test starts all instances, need to reconsider this test
case. The bug reported here not withstanding, it may be better to:
- if no 'create_image' action was found on the instance in a running state
- stop the instance and then check for the create_image action
As things stand, we loose test coverage by skipping the test point for all
providers where the action is available for stopped instances
> RHEVM instances in RUNNING state show create_image actions - but creating an
> image from a running instance throws a 500 error

> RHEVM 3.1
> Reporter: Ronelle Landy

> Found by running the white box tests ....
> Below is one instance returned from executing a GET /api/instances - provider
> is RHEVM 3.1. Notice that the create_image operation is returned even though
> the instance is in a RUNNING state.
> However, is you try create an image from a running instance in RHEVM. you get
> a 500 error (ERROR -- 500: [Deltacloud::Exceptions::BackendError] Cannot add
> Template. VM still running, stop the VM and try again.) Full trace copied at
> the end of this description.
> deltacloud/tests/deltacloud/instance_test.rb checks if the create_image op is
> returned and if so, attempts to create an image. In this case, where the VM
> is RUNNING, the test errors out. Since we have seen this test run cleanly in
> the past, I'm sort of curious what's going on here.....
