I have a `default` network with the following definition:

 mrostecki  ~  sudo virsh net-dumpxml default
<network>
  <name>default</name>
  <uuid>427c041e-0ede-4d0a-abd9-0bf104eefdbd</uuid>
  <forward mode='nat'/>
  <bridge name='virbr0' stp='on' delay='0'/>
  <mac address='52:54:00:f2:2f:d7'/>
  <ip address='192.168.122.1' netmask='255.255.255.0'>
    <dhcp>
      <range start='192.168.122.2' end='192.168.122.254'/>
    </dhcp>
  </ip>
</network>

It's supposed to autostart:

 mrostecki  ~  sudo virsh net-list --all
 Name      State      Autostart   Persistent
----------------------------------------------
 default   inactive   yes         yes

Every time when libvird starts on the system boot, it fails with the following eror

 mrostecki  ~  sudo journalctl -u libvirtd
