最近同事在用icehouse版本nova的baremetal driver在CentOS6.3上遇到了一些坑。之前对这块没什么了解，简单记录如下： 1.  启动时发现Bad or missing multicast discovery address:
调试发现dhcp server在回包时没有包含TFTP Server的地址，最终发现是dnsmasq的版本过低造成的。升级到2.66就解决了。

2.  "Unable to locate configuration file"

最后定位发现是在CentOS6.3上tftp配置的不对：

[root@ocpdev002 tftpboot]# pwd 
/tftpboot 
[root@ocpdev002 tftpboot]# ll 
total 40 
-rw-r--r-- 1 nova nova 23 Sep 5 01:07 map-file 
-rw-r--r-- 1 nova nova 26595 Sep 5 01:10 pxelinux.0 

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 \ 
# 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 
{ 
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 
}

你好，我是世纪雅思的，很高兴为你解答：

你可看看我们总结的HOT TOPIC

1. Why parents would prefer to home school their children?
Parents prefer to home school their children because it has been observed that children who are home schooled tend to be able to make it to international universities. Most people would be concerned about the child having an abnormal social life as he will not have any classmates when he is home schooled. Surprisingly, home schooled children seemed to be well rounded as compared to children who go to the traditional schooling. Parents can pay particular attention on the weakness of the child and focus on how to improve this when home schooling.

2. What are the advantages of Chinese education that you think should be passed on to the next generation?
Chinese characters seem to be complicated, yet very interesting because each stroke and character has a meaning of its own. When a character is combined with another character, the meaning becomes different already. Chinese history is very rich in culture and values which are essential in one’s character and lifestyle. Sadly, not all the Chinese are lucky enough to be able to learn all these things.

3. Do you think that having a 9 year-compulsory schooling is enough to have a bright future?
I am not convinced about the idea that a 9-year compulsory schooling is enough to have a bright future. It would really depend on the child’s emotional maturity, character, capacity, intellect and resilience to be able to hav......余下全文>>
