Description Ondra Machacek 2013-08-28 09:19:37 UTC 
Description of problem:
When service ovirt-scheduler-proxy is not running and user have defined external scheduler in cluster policy, then there is no information that his scheduler was not used.

Version-Release number of selected component (if applicable):
is11

How reproducible:
always

Steps to Reproduce:
1. add some filter to /usr/share/ovirt-scheduler-proxy/plugins/
2. service ovirt-scheduler-proxy start
3. Allow external scheduler to engine (rhevm-config -s ExternalSchedulerEnabled=true && service ovirt-engine restart)
4. service ovirt-scheduler-proxy stop
5. Create new cluster policy and use your filter.
6. Create vm with disk in cluster and run vm.

Actual results:
Vm run.

Expected results:
Vm run. And event is generated, that external scheduler couldn't be used.

Vm is failed to run with message "Failed to run VM vm_proxy (User: admin@internal)."
In engine log "Could not communicate with the external scheduler while running weight modules"
Please add appropriate message to events.
Comment 2 Noam Slomianko 2013-10-21 11:23:46 UTC 
If no internal scoring function was selected and the external scheduler returned no results a situation occured where no host would be selected at all
Added a fix

Artyom,
a VM should be scheduled even if the the external proxy is down,
since we can use which ever internal policy parts we have. So this is
working be design.

he question is if you got an indication on the scheduler being down. for example,
are the external policy elements marked as disabled?
Comment 7 Martin Sivák 2013-11-06 15:31:54 UTC 
There seems to be no indication of this in the engine. Moreover the user has a limited chance of spotting this as we do not use the external scheduler in canDoAction.
Comment 8 Artyom 2013-12-16 12:10:07 UTC 
Verified on is27,
Cluster policy with external cost and filter functions, ovirt-scheduler-proxy stopped, vm run fine and also error message in engine events:
"Failed to connect to external scheduler proxy. External filters, scoring functions and load balancing will not be performed."
