The 'default' is whatever your management app decides is the default
(if any), which has nothing todo with what XenD creates  by default.
virt-install will default to the bridge associated with the default
route, if none is found it'll use the first libvirt virtual network
it finds. Fedora does not create 'xenbr0' in a standard install so
the virbr0 will always be used unless the admin has configured full
bridging. Even if the admin has got bridging configured, the prescence
of virbr0 does not impact that functionality.
