I create a windows domain in VirtualMachine.Now I install a CentOs 6.4 and I want to jion it to my domain.But at the first my CentOs must has DHCP Ip Address but I have IPV4_FAILURE_FATAL=yes and Ip do not assign.Beside I just enable IPV4 . What should I do?

To poll an IP address from a DHCP server, you must have a DHCP server accessible one the network segment.
Since you are building a virtual environment, it's not likely you did that first so the easiest solution would be to assign IP address until you get a DHCP server running on the segment.

Not sure where you're reading that from but that more likely means failure to have access to the IP4 network is fatal to the process that message is attached to, not kill the IPV4 process.

To help us.
From a command terminal on the instance, type in ifconfig -a and post the result.

I have a DHCP Server,And assigns ip to clients domain.

[Barran@localhost ~]$ ifconfig -a

You polled an IP address and are passing packets over the interface
Where did your error come from?

When I write this command ------> vi /etc/sysconfig/network-scripts/ifcfg-eth0
I see this---->
EVICE="eth0"
BOOTPROTO=dhcp
IPV6INIT=no
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="c8b803bb-819d-4e84-b198-3cd8d9b98b6b"
DEFROUTE=yes
IPV4_FAILURE_FATAL=yes
NAME="System eth0"
IPV6_AUTOCONF=no
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=yes
HWADDR=00:0C:29:53:8F:48
PEERDNS=no
PEERROUTES=yes

That's the configuration file for the interface
NAME="System eth0"
Good ol' eth0...
When you tell the machine to configure the base ethernet port (eth0) it reads those values and builds it accordingly.
It's a configuration file, not a diagnostic output.
