In the past, the MTU of libvirt virtual network bridge devices was implicitly set by setting the MTU of the "dummy tap device" (which was being added in order to force a particular MAC address from the bridge). But the dummy tap device was removed in commit ee6c936fbb (libvirt-6.8.0), and so the mtu setting in the network is ignored. The solution is, of course, to explicitly set the bridge device MTU when it is created. Note that any guest interface with a larger MTU that is attached will cause the bridge to (temporarily) assume the larger MTU, but it will revert to the bridge's own MTU when that device is deleted (this is not due to anything libvirt does; it's just how Linux host bridges work).

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.
