Fedora 9, KVM GuestOS PXE boot

Here is my quick howto reference on PXE boot enabling for KVM guests under Fedora 9 using virt-manager.

(Having NetworkManager & network service disabled , host system obtains address via DHCP on its eth0)

--snip--

Setup:
# chkconfig network off
# chkconfig NetworkManager off
# service NetworkManager stop

# brctl addbr br0
# brctl addif br0

# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
#BOOTPROTO=dhcp
HWADDR=yo:ur:ma:ac:aa:dd
ONBOOT=yes
BRIDGE=br0

# cat /etc/sysconfig/network-scripts/ifcfg-br0
DEVICE=br0
BOOTPROTO=dhcp
ONBOOT=yes
TYPE=bridge

# modprode tun
# ifup lo
# ifup eth0
# ifup br0

Make it persistent:

# cat /etc/rc.local
modprobe tun
ifup lo
ifup eth0
ifup br0

touch /var/lock/subsys/local

--snip--

I yet need to figure out how to make br0 come up first by using network service-script or a more simpler way to get this done. If any one else knows a better & more tested procedure then please share.

My sequence shared here might not be correct since I had to struggle for few minutes before I got this working for me. Thanks to Niranjan for providing pointers on how to get this solved in first place.
