[ OST Failure Report ] [ oVirt 4.2 (ovirt-engine) ] [ 05-03-2018 ] [ 006_migrations.migrate_vm ]

[Dafna Ron]

Hi,

We have a failure in OST on test 006_migrations.migrate_vm.

>From what I can see, the migration succeeded but because there was a
KeyError: 'cpuUsage' engine assume the v is down and tries to retry
migration.
the re-try fails with vm already exists.
