When removing 10 vms simultaneously only 8-9 of events with type=36 are reported. Found in automated rest api tests: http://<hist>/api/events?search=type%3D36
You should use type 113 for it, not 36 !!! please note that type 36 only reports on removal initialization since the VM may have images to remove and that is an async operation. The message format on type 36 is: Removal of VM <vm> was initiated by <user>. while teh message format on type 113 is: VM <vm> was successfully removed. Please allign your tests to use type 113 if you want to see which VMs completes removal (i.e. finished to remove also the VM images)
