This leads to another traceback when starting the VM:
Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/engine.py", line 493, in run_domain
    vm.startup()
  File "/usr/share/virt-manager/virtManager/domain.py", line 573, in startup
    self.vm.create()

    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: internal error Failed to add tap interface 'vnet%d' to
