[ovirt-users] Live storage migration is failing in 4.2.8

Hello, we have recently updated few ovirts from 4.2.5 to 4.2.8 version (actually 9 ovirt engine nodes), where the live storage migration stopped to work, and leave auto-generated snapshot behind. If we power the guest VM down, the migration works as expected. Is there a known bug for this? Shall we open a new one?
