rhel6下pxe网络引导安装的问题

请高手看看我这里配置哪里出错了，我开虚拟机测试安装的时候一直出现
tftp：//0.0.0.0/...........connection timed out (Ox4c126035)
could not load tftp://0.0.0.0/: connection timed out (Ox4c126035)
No more network device
No bootable device这个错误，我在dhcp配置文件里加了next-server 192.168.1.100
求高人指点 谢谢

[root@rhel6 ~]# cat /etc/xinetd.d/tftp
# default: off
# description: The tftp server serves files using the trivial file transfer \
#    protocol.  The tftp protocol is often used to boot diskless \
#    workstations, download configuration files to network-aware printers, \
#    and to start the installation process for some operating systems.
service tftp

    disable    = no
    socket_type        = dgram
    protocol        = udp
    wait            = yes

}

dhcp配置：

ddns-update-style none;
ignore client-updates;
allow booting;
allow bootp;
subnet 192.168.1.0 netmask 255.255.255.0 {

    option routers             192.168.1.1;   #我用的路由器上网，路由的IP是192.168.1.1
