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
