Certain CNIs, such as Calico and Cilium, do not currently support live migration.

However, there is no explicit validation or blocking condition in KubeVirt/OpenShift Virtualization to prevent live migration when such CNIs are in use.
--------------
From the KubeVirt codebase, the following condition is considered for the network requirement:
`cannot migrate VMI which does not use masquerade or a migratable plugin to connect to the pod network`
https://github.com/kubevirt/kubevirt/blob/6becdb4d94d1e3ba143e8d095c89024630e2ff6a/pkg/network/vmispec/interface.go#L87C1-L88C1

Even the documentation does not comment on any such condition:
 https://docs.redhat.com/en/documentation/openshift_container_platform/4.20/html/virtualization/live-migration#live-migration-requirements_virt-about-live-migration

Everytime

1. Ensure CNI such as calico, cilium are in use
2. live-Migrate VM 

VMI is marked as liveMigratable: True

VMI should get marked as liveMigratable: False

There is no condition specified that explicitly blocks live migration when the CNI in use does not yet support live migration. 
As a result, the VM is able to initiate migration, but the migration gets stuck with the issues mentioned in
