NetworkManager fails while installing Fedora 12 guest os


Hi

I'm trying to install Fedora 12 guest on a Fedora 12 host using KVM via virt-install.I want to access the guest from other hosts, so I need a network bridge. When I try to install the guest it shows a message:
Quote:
Waiting for NetworkManager to configure eth0.
After a while it shows an error message:
Quote:
There was an error configuring your network interface.
After selecting the retry button of it, another message is appeared saying that it cannot find the kickstart file, selecting the cancel button I am able to specify network configuration manually. When I set this settings manually NetworkManager is able to configure the network interface. I don't know what goes wrong when I try to install the guest using kickstart file. The file is accessible by the address specified.

Here is the configuration files and commands that I used:

network interfaces:
Quote:
cat ifcfg-eth0

# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]
DEVICE=eth0
HWADDR=00:0C:29:60:A0:25

Contents of sysctl.conf:

Quote:
cat /etc/sysctl.conf

# Kernel sysctl configuration file for Red Hat Linux
#
# For binary values, 0 is disabled, 1 is enabled. See sysctl(8) and
# sysctl.conf(5) for more details.

# Controls IP packet forwarding
net.ipv4.ip_forward = 0

# Controls source route verification
net.ipv4.conf.default.rp_filter = 1

# Do not accept source routing
net.ipv4.conf.default.accept_source_route = 0

# Controls the System Request debugging functionality of the kernel
kernel.sysrq = 0

# Controls whether core dumps will append the PID to the core filename.
# Useful for debugging multi-threaded applications.
kernel.core_uses_pid = 1

# Disable netfilter on bridges.
#net.bridge.bridge-nf-call-ip6tables = 0
#net.bridge.bridge-nf-call-iptables = 0
#net.bridge.bridge-nf-call-arptables = 0
I used the following commands and commented out the last three lines of sysctl.conf:
Quote:
iptables -I FORWARD -m physdev --physdev-is-bridged -j ACCEPT
service iptables save
service iptables restart
The virt-install command that is used:
Quote:
virt-install --name myfed12 --ram 512 --disk path=/home/images/fed12.img,size=8 --network bridge=MPM_br0 --os-type=linux --os-variant=fedora12 -l http://192.168.1.1/fedora -x ks=http://192.168.1.1/ks.cfg
The host os is also a virtual host (vmware guest).
