Comment 4 Denys Shchedrivyi 2022-02-04 19:49:56 UTC 
Verified on CNV v4.9.3-16

In virt-controller logs I see the message about hitting the migration limits:

{"component":"virt-controller","kind":"","level":"info","msg":"Waiting to schedule target pod for vmi [default/vm-5] migration because total running parallel outbound migrat
ions on target node [2] has hit outbound migrations per node limit.","name":"job-5","namespace":"default","pos":"migration.go:714","timestamp":"2022-02-04T19:37:19.968194Z",
"uid":"d9d535b9-8062-4428-b664-9c6badda2a8a"}


And VMIM objects look much more informative:

$ oc get vmim -o wide
NAME    PHASE        VMI
job-1   Succeeded    vm-1
job-2   Succeeded    vm-2
job-3   Running      vm-3
job-4   Scheduling   vm-4
job-5   Pending      vm-5
