最后定位发现是在CentOS6.3上tftp配置的不对：

drwxr-xr-x 2 nova nova 4096 Sep 5 01:35 pxelinux.cfg 

[root@ocpdev002 tftpboot]# cat map-file 
r ^([^/]) /tftpboot/\1

[root@ocpdev002 tftpboot]# cat /etc/xinetd.d/tftp 
# default: off 
# description: The tftp server serves files using the trivial file transfer \

service tftp 
{ 
socket_type = dgram 
protocol = udp 
wait = yes 
user = root 
server = /usr/sbin/in.tftpd 
server_args = --map-file /tftpboot/map-file /tftpboot 
disable = no 
per_source = 11 
cps = 100 2 
flags = IPv4 
}
