qemu dhcp server doesn't work.

my freebsd virtual machine can't connect the internet ,and virt-manager's NIC shows that my ip is unknown.
It seems that dhcp server doesn't work,but i don't know how to solve this problem.
There are some info:

network xml:

<interface type="network">
  <mac address="52:54:00:89:28:2c"/>
  <source network="default" portid="5846c7ad-2afe-4a5d-8789-468fe0299bf3" bridge="virbr0"/>
  <target dev="vnet0"/>
  <model type="virtio"/>
  <link state="up"/>
  <alias name="net0"/>
  <address type="pci" domain="0x0000" bus="0x04" slot="0x00" function="0x0"/>
</interface>

and in my virtual machine, there are two network interface "lo0" and "vnet0"
vnet0 is active ,but i found:

inet 0.0.0.0 netmask 0xff000000 broadcast 255.255.255.255
