nvazquez commented on issue #2466: Rare race condition in KVM migration
URL: https://github.com/apache/cloudstack/pull/2466#issuecomment-367991052
   Hi @rafaelweingartner, let me answer your questions by explaining the issue 
in a better way:
   This is issue is reported under these conditions:
   - VM migration has physically finished
   - Migration thread executor is still not marked as terminated
   From the migration monitoring process, as VM has been migrated, that domain 
cannot be found (we should get the destination domain from the migration thread 
later) and the LibvirtException is thrown: `LibvirtException ?Domain not found: 
no domain with matching uuid?`.
   So basically the idea is just logging the issue but not suspending the VM as 
the migration has already been performed, but the migration thread is not 
marked as finished. Once the migrarion thread is marked as finished, the 
migration monitoring process (while loop) ends and the migration command 
wrapper would continue its execution.
   Regarding your last question, we won't need to suspend the VM in this case 
as the migration has already been performed. VM suspension will take place 
whenever the migration is in progress and those conditions are met
