managed='no' on an <interface> allows an unprivileged libvirt to use a pre-created tap/macvtap device that libvirt has permission to open/read/write, but no permission to modify (i.e. set the MTU or MAC address). But when the XML had an <mtu size='blah'/> setting (which was put there in order to tell the *guest* OS what MTU to set for the emulated device at the other end of the tap) we were attempting to set the MTU of the tap device on the host, paying no attention to the setting of 'managed'. That would of course end in failure. This patch only sets the MTU if managed='no' is *not* set (so, if it is 'yes', or just not set at all). Note that MTU of the tap is also set when connecting the tap to a bridge device, but managed='no' is only allowed for <interface type='ethernet'>, which would never attach to a bridge anyway, so we don't need the check there.

==============================
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:
