Our documentation says RDMA migration requires hard_limit to be set so that we know how big memory locking limit should be set for the domain during migration. But since commit v1.2.13-71-gcf521fc8ba (which changed the default hard_limit value from 0 to VIR_DOMAIN_MEMORY_PARAM_UNLIMITED) we were actually setting memlock limit to unlimited if hard_limit was not set.
