nvazquez opened a new pull request #2466: Rare race condition in KVM migration
URL: https://github.com/apache/cloudstack/pull/2466
 
 
   There is a race condition in the monitoring of the migration process on KVM. 
If the monitor wakes up in the tight window after the migration succeeds, but 
before the migration thread terminates, the monitor will get a LibvirtException 
?Domain not found: no domain with matching uuid? when checking on the migration 
status. This in turn causes CloudStack to sync the VM state to stop, in which 
it issues a defensive StopCommand to ensure it is correctly synced.
   
   Fix: Prevent `LibvirtException: "Domain not found"` caused by the call to 
`dm.getInfo()`
