We have introduced support for parallel migration connections some time ago but it is not configurable via the REST API. Support for configuring the corresponding cluster and VM migration properties should be added to the REST API.
Setting high severity since it is needed for automated tests
The verification here should ideally be adding an automated test for setting parallel migration
Verified with: ovirt-engine-4.5.1.2-0.11.el8ev.noarch vdsm-4.50.1.3-1.el8ev.x86_64 Steps: Run all test cases in the attached Polarion test plan using REST API. Results: All cases passed.
