Hi team! When we try to create lb from harvester, sometimes it can't provide external ip to lb service. Did you face this issue? Why it happens, any idea?

The LB gets attached to the mgmt network interface on the host boxes. If you've separated the VM networks to a different interface and the VLANs aren't routable from the mgmt network, the LB connections can't succeed.

Both uses mgmt interface but still lb can't get ip. Actually most of the time Lb gets external ip, but sometimes it's external ip in pending state

If you

kubectl get events

and

kubectl describe <your-ip-resource>

what do you get ?
