when scheduling migrations to accommodate the controller_max_vm_inflight setting for vSphere, we didn't take into account that disks are transferred sequentially by virt-v2v (as opposed to CDI that transfers them in parallel by different pods). This lead to performance degregeration since could have triggered more migrations, in case of migrations of multi-disk VMs, simultaneously without exceeding the value of controller_max_vm_inflight. This is fixed by setting the cost of each VM for which the disks are transferred by virt-v2v to 1. Signed-off-by: Arik Hadas <[email protected]>
When looking for the configuration of an ESXi host that a certain VM resides on, we query all the hosts in the namespace and then looking for the host by its MOR (Managed Object Reference). This almost always works but it could be wrong when there are several providers within the same namespace that refer to the same host. This is more likely to happen during tests where we define two providers with different propreties for the same vSphere environment. Therefore, adding another check that ensures the host refers to the provider which is the source provider on the plan of the migrated VM, otherwise skip that host.

It could be that we have VMs for which the migration is marked as started and not marked as completed in archived plans. From now on, we will not take such VMs into account when counting the inflight VMs. Signed-off-by: Arik Hadas <[email protected]>
