At live migration the IP has to follow the VM and at kubevirt it means that the new virt-launcher pod has to re-use the address from the old virt-launcher. This change annotate the new virt-launcher pods with the ip configuration of the old one so ipam can take over. Signed-off-by: Enrique Llorente <[email protected]>
