[libvirt-users] I have ping through bridge , net has been started , But IPs they're not equivalent.



Dear All,

I have the following configuration and I have ping from bridge :

/////////////////////////////////////////////////////
iface eth0 inet static
        address 192.168.1.4
        netmask 255.255.255.0
        network 192.168.1.0
        broadcast 192.168.1.255
        gateway 192.168.1.1
auto ivbr0
iface ivbr0 inet static
        address 192.168.1.4
        netmask 255.255.255.0
        network 192.168.1.0
        broadcast 192.168.1.255
        gateway 192.168.1.1
        bridge_ports eth0
        bridge_stp on
        bridge_maxwait 0
        bridge_fd 0

/////////////////////////////////////////////
# brctl show
bridge name    bridge id        STP enabled    interfaces
ivbr0        8000.18037360b44e    yes        eth0
/////////////////////////////////////////////
my network xml file :
<network>
  <name>myintranet</name>
  <uuid>465ce6cb-0a69-4f89-92ba-629349741e73</uuid>
  <forward mode='nat'>
       <interface dev="eth0" />
  </forward>
  <bridge name='ivbr0' stp='on' delay='0' />
  <mac address='52:54:00:0f:f4:f0'/>
  <ip address='192.168.1.4' netmask='255.255.255.0'>
    <dhcp>
      <range start='192.168.1.3' end='192.168.122.254'/>
    </dhcp>
  </ip>
</network>
////////////////////////////////////////////
Now , I have ping of my modem and internet.
Then I did the following command :
# ip l set dev ivbr0 down
# brctl delbr ivbr0
# virsh net-start myintranet
Network myintranet started

According to above , myintranet network has been started. But with the following IP address :
# ip a show dev ivbr0
17: ivbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default
    link/ether 52:54:00:0f:f4:f0 brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.1/24 brd 192.168.122.255 scope global ivbr0
       valid_lft forever preferred_lft forever
////////

192.168.122.1 ?
Question is , Where I change this address?(I set in myxml file.)

--best regards
Mohsen
