In a domain created with an interface with a <driver> subelement, the device contains a non-NULL virDomainVirtioOptions struct, even for non-virtio NIC models. The subelement need not be present again after libvirt restarts, or when the interface is passed to clients. When clients such as virsh domif-setlink put back the modified interface XML, the new device's virtio attribute is NULL. This may fail the equality checks for virtio options in qemuDomainChangeNet, depending on whether libvird was restarted since define or not. This patch modifies the check for non-virtio models, to ignore olddev value of virtio (assumed valid), and to allow either NULL or a struct with all values ABSENT in the new virtio options.

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.
