I use bridge network on host to install the guest,part of the guest xml file:
  <interface type='bridge'>
      <source bridge='br0'/>
      <model type='e1000'/>
    </interface>

1. Check the iptable.
# service iptables status
Table: nat
Chain PREROUTING (policy ACCEPT)
num  target     prot opt source               destination         

Chain POSTROUTING (policy ACCEPT)
num  target     prot opt source               destination         
1    MASQUERADE  tcp  --  192.168.122.0/24    !192.168.122.0/24    masq ports:
1024-65535 
2    MASQUERADE  udp  --  192.168.122.0/24    !192.168.122.0/24    masq ports:
1024-65535 
3    MASQUERADE  all  --  192.168.122.0/24    !192.168.122.0/24    

Chain OUTPUT (policy ACCEPT)
num  target     prot opt source               destination         

Table: filter
Chain INPUT (policy ACCEPT)
num  target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
num  target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
num  target     prot opt source    
           destination    
2.On host, delete the 1th and 2th rules in POSTROUTING chain of nat table.
# iptables -t nat -D POSTROUTING 1
# iptables -t nat -D POSTROUTING 1
# iptables -t nat -L
Chain PREROUTING (policy ACCEPT)
target     prot opt source               destination         

Chain POSTROUTING (policy ACCEPT)
target     prot opt source               destination         
MASQUERADE  all  --  192.168.122.0/24    !192.168.122.0/24    

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination  

3.Then I use nat network to install the guest,it also can't work.
