[libvirt] Assigning a static IP to the Linux Container through libvirt.

Hi, I want to assign a static IP 172.16.1.20 to one of the containers created using libvirt. For that, I defined a network 'mynetwork' using net-define. The XML format for that network is shown below: <network> <name>mynetwork</name> <uuid>f76c44dd-bcef-6b45-4a50-00d575a369ad</uuid> <bridge name='virbr1' stp='on' delay='0' /> <ip address='172.16.1.20' netmask='255.255.255.0'> </ip> </network> I started the network 'mynetwork' using net-start. virsh # net-list --all Name State Autostart ----------------------------------------- default active yes mynetwork active no I created a domain 'vm1_fedora' with libvirt XML: <domain type='lxc' id='1'> <name>vm1_fedora</name> <memory>500000</memory> <os> <type>exe</type> <init>/bin/bash</init> </os> <vcpu>1</vcpu> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/libexec/libvirt_lxc</emulator> <filesystem type='mount'> <source dir='/root/lxc/fedora12'/> <target dir='/'/> </filesystem> <filesystem type='mount'> <source dir='/root/lxc/fedora12/dev'/> <target dir='/dev'/> </filesystem> <interface type='network'> <source network='mynetwork'/> </interface> <console type='pty' /> </devices> </domain> But, when I start that domain and see for 'ifconfig', I am not able to see the IP address 172.16.1.20 there. [root@localhost /]# ifconfig eth0 Link encap:Ethernet HWaddr 52:54:00:53:4D:BF inet6 addr: fe80::5054:ff:fe53:4dbf/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:18 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:840 (840.0 b) TX bytes:384 (384.0 b) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) can you please let me know, how can I assign a static IP to the Linux Container?
