Can't setup static IP

satimis · 01-15-2010, 08:31 AM

Hi folks,

Problem to setup static IP

Host - Fedora 12 64bit
KVM - virtualization software
VM04 - Fedora 12 64bit
VM01 - Debian 5.0 64bit
VM02 - Debian 5.0 64bit
VM03 - Ubuntu 9.10 64bit

I have been tweaking a whole day unable to setup static IP on VM04, always staying on dynamic IP, 192.168.0.18, which was first detected before setting static IP

VM04
$ cat /etc/sysconfig/network-scripts/ifcfg-eth0

Code:

# Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+
DEVICE=eth0
IPADDR=192.168.0.204
NETMASK=255.255.255.0
BOOTPROTO=static
HWADDR=52:54:00:7F:1C:2D
ONBOOT=yes
TYPE=bridge
DEFROUTE=yes
NAME="System eth0"
UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03
DNS1=202.14.67.4
DNS2=202.14.67.14
NM_CONTROLLED=yes
IPV6INT=no
USERCTL=no
GATEWAY=192.168.0.1
PEERDNS=yes
PEERROUTES=yes

On Host:-
[satimis@fedora12 ~]$ route

Code:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.0.0     *               255.255.255.0   U     0      0        0 br0
192.168.122.0   *               255.255.255.0   U     0      0        0 virbr0
link-local      *               255.255.0.0     U     1003   0        0 br0
default         192.168.0.1     0.0.0.0         UG    0      0        0 br0

$ sudo brctl show

Code:

bridge name	bridge id		STP enabled	interfaces
br0		8000.00261844b61a	no		eth0
							vnet0
virbr0		8000.000000000000	yes

Do I need to create;
/etc/qemu-ifup

Code:

bridge=virbr0
ifconfig $1 0.0.0.0 up
brctl addif $bridge $1 || true

and

/etc/qemu-ifdown

Code:

bridge=virbr0
brctl delif $bridge $1 || true
ifconfig $1 down

???

However VM1, VM2 and VM3 don't have problem. They work with static IP

Please help. TIA

B.R.

Hi -

This is a longshot, but:

VM04
$ cat /etc/sysconfig/network-scripts/ifcfg-eth0

Do you have a second "ifcfg-eth*" file, one for the MAC? And did you change it (to static) too?

$ ls /etc/sysconfig/network-scripts/ | grep ifcfg

Code:

ifcfg-eth0
ifcfg-lo

$ cat /etc/sysconfig/network-scripts/ifcfg-lo

Code:

 
DEVICE=lo
IPADDR=127.0.0.1
NETMASK=255.0.0.0
NETWORK=127.0.0.0
# If you're having problems with gated making 127.0.0.0/8 a martian,
# you can change this to something else (255.255.255.255, for example)
BROADCAST=127.255.255.255
ONBOOT=yes
NAME=loopback
