While QEMU accepts and interprets an empty string in the tls-hostname field in migration parametes as if it's unset, the same does not apply for the 'tls-hostname' field when 'blockdev-add'-ing a NBD backend for non-shared storage migration. When libvirt sets up migation with TLS in 'qemuMigrationParamsEnableTLS' the QEMU_MIGRATION_PARAM_TLS_HOSTNAME migration parameter will be set to empty string in case when the 'hostname' argument is passed as NULL. Later on when setting up the NBD connections for non-shared storage migration 'qemuMigrationParamsGetTLSHostname', which fetches the value of the aforementioned TLS parameter. This bug was mostly latent until recently as libvirt used MIGRATION_DEST_CONNECT_HOST mode in most cases which required the hostname to be passed, thus the parameter was set properly.

==============================
Libvirt API for virtualization
==============================
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.
Further information about the libvirt project can be found on the
website:
