source pod stays in "completed" state after live migration

[Olivier Matz]

Hello,

I'm experimenting live migration with kubevirt. After the live migration is successful, the source pod is not removed and remains in a "completed" state:

root@vm-k8s-hypervisor:~# kubectl get pod -n red
NAME                       READY   STATUS      RESTARTS   AGE
virt-launcher-red1-2klb8   3/3     Running     0          39s
virt-launcher-red1-l8sfq   0/3     Completed   0          102s

I would have expected that it is deleted automatically but I don't find something in the documentation that explicitly confirms this. On the other hand, I found this link https://kubevirt.io/labs/kubernetes/migration.html that tends to show that it is a normal behavior (see the bottom of the page).

Could you please let me know if this is the expected behavior? If not, I’d be happy to open a GitHub issue with all the necessary details.

Thanks

Olivier

Hello Olivier,

Yes this is the expected behavior. The source pod is only deleted when the VM is shutdown.
