vm events

Description of problem:
The events of VM creation/deletion is not according to the creation/deletion of a VM, it's according to start/stop a VM. It's confusing to me that If I create a VM on UI, and then go to events page, choose VirtualMachine type, I cannot see any events, but If I start the VM, I can see a event like "Created virtual machine: example". This is not correct, start a VM is creating a virtualmachine instance. Same for delete the VM, after delete the VM, no events generated for VM in events page, but stop a VM could see "Deleted virtual machine: feb187b4-545a-11e9-9e6e-fa163ecbb3d0" in events within VirtualMachine type.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. create a vm, no events for VM
2. start a vm, event like "Created virtual machine: example"
3. stop a vm, event like "Deleted virtual machine: feb187b4-545a-11e9-9e6e-fa163ecbb3d0"
4. delete a vm, no events for VM

Actual results:

Expected results:

Comment 1 Fabian Deutsch 2019-04-01 09:49:50 UTC
For this scenarion we probably want to adjust the message the vm controller is emitting. As the current message "Created virtual machine: example" is wrong, if, then it should be: "created virtual machine instance: example"

What about letting the vm controller emit:

"Started the virtual machine by creating the new virtual machine instance 'example'"


"Stopped the virtual machine by deleting the virtual machine instance 'example'"

Setting the priority to high, as it's visible in the UI.

Comment 2 Guohua Ouyang 2019-04-01 12:57:49 UTC
It looks we're going to sovle it by improving the start/stop message. I have one more concern is should it also have event for create/delete a vm?

Comment 3 Fabian Deutsch 2019-04-01 12:59:45 UTC
Create/delete for a VM (VirtualMachine) is just like fro any other object. I'd not add explicit messages for this.
