Can't get Virtual Network Setup in KVM

[Jim]

1.  Installing KVM, In these instructions under # 1 have been completed, 
Network setup is problem.

Fedora 12 KVM Host:

First check if your CPU supports hardware virtualization - if this is 
the case, the command
egrep '(vmx|svm)' --color=always /proc/cpuinfo
should display something, e.g. like this:

[root at server1 ~]# egrep '(vmx|svm)' --color=always /proc/cpuinfo
  flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge 
mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall
   nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow rep_good nopl pni cx16 
lahf_lm cmp_legacy svm extapic cr8_legacy 3dnowprefetch
  flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge 
mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall
   nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow rep_good nopl pni cx16 
lahf_lm cmp_legacy svm extapic cr8_legacy 3dnowprefetch

[root at server1 ~]#
If nothing is displayed, then your processor doesn't support hardware 
virtualization, and you must stop here.
To install KVM and virtinst (a tool to create virtual machines), we run
yum install kvm qemu libvirt python-virtinst

Then start the libvirt daemon:
/etc/init.d/libvirtd start

To check if KVM has successfully been installed, run
virsh -c qemu:///system list
It should display something like this:
[root at server1 ~]# virsh -c qemu:///system list
   Id Name                 State
  ----------------------------------

  [root at server1 ~]#
If it displays an error instead, then something went wrong.
Next we need to set up a network bridge on our server so that our 
virtual machines can be accessed from other hosts as if they were 
physical systems in the network.
To do this, we install the package bridge-utils...
yum install bridge-utils





2. Trying to setup a Virtual Network using KVM .

No network connection, Network Manager is OFF.

The /etc/sysconfig/network scripts  br0, eth0  are shown below.

I can't get a "virbro" in ifconfig.

The Network Configuration shows   br0 is Active and    eth0 is Inactive .


3. The setup instructions are below with ifcfg-br0, ifcfg-eth0 and the 
ifconfig output.


Next we need to set up a network bridge on our server so that our 
virtual machines can be accessed from other hosts as if they were 
physical systems in the network.
To do this, we install the package bridge-utils...
yum install bridge-utils

... and configure a bridge.
I disable Fedora's NetworkManager and enable "normal" networking. 
NetworkManager is good for desktops where network connections can change 
(e.g. LAN vs. WLAN), but on a server you usually don't change network 
connections:

chkconfig NetworkManager off
  chkconfig --levels 35 network on
  /etc/init.d/network restart

Check your /etc/resolv.conf if it lists all nameservers that you've 
previously configured:
cat /etc/resolv.conf
If nameservers are missing, run
system-config-network
and add the missing nameservers again.


Nameservers are in /etc/resolv.conf.


To configure the bridge, create the file 
/etc/sysconfig/network-scripts/ifcfg-br0 (please use the BOOTPROTO, DNS1 
(plus any other DNS settings, if any), GATEWAY, IPADDR, NETMASK and 
SEARCH values from the /etc/sysconfig/network-scripts/ifcfg-eth0 file):
vi /etc/sysconfig/network-scripts/ifcfg-br0
VICE=br0
TYPE=Bridge
BOOTPROTO=static
DNS1=127.0.0.1
DNS2=172.16.0.1
GATEWAY=172.16.0.1
IPADDR=172.16.1.101
NETMASK=255.255.255.0
ONBOOT=yes
IPV6INIT=no
USERCTL=no


   Modify /etc/sysconfig/network-scripts/ifcfg-eth0 as follows (comment 
out BOOTPROTO, DNS1 (and all other DNS servers, if any), GATEWAY, 
IPADDR, NETMASK, and SEARCH and add BRIDGE=br0):
vi /etc/sysconfig/network-scripts/ifcfg-eth0
# Networking Interface
# Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit 
Ethernet controller
DEVICE=eth0
HWADDR=6C:F0:49:06:47:CB
TYPE=Ethernet
#BOOTPROTO=none
#NAME="System eth0"
UUID=5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03
ONBOOT=yes
#PEERROUTES=yes
NM_CONTROLLED=no
IPV6INIT=no
USERCTL=no
BRIDGE=br0

   Then reboot the system:
reboot
After the reboot, run
ifconfig
It should now show the network bridge (br0):
[root at server1 ~]# ifconfig
