Open Stack

I use CentOS6.2 as Server and I solve this problem by :

iptables -A POSTROUTING -t mangle -p udp --dport bootpc -j CHECKSUM
--checksum-fill

from http://www.mail-archive.com/kvm@vger.kernel.org/msg41958.html

It looks like a bug for centos

Thanks

Subject: [Openstack] lease ip problem with ubuntu
To: Openstack <openstack at lists.launchpad.net>


My ubuntu instance can't get leased IP address, CentOS instance image is OK
with that

I boot up ubuntu instance and run dhclient eth0 manually, I can see
packages from server side, I don't know why ubuntu can't get address :
12:44:11.973930 IP 0.0.0.0.bootpc > 255.255.255.255.bootps: BOOTP/DHCP,
Request from fa:16:3e:74:22:48 (oui Unknown), length 300
12:44:11.974184 IP 10.0.1.3.bootps > 10.0.1.15.bootpc: BOOTP/DHCP, Reply,
length 300

In guest ubuntu's syslog I find:
5 bad udp checksums in packets

I am thinking if it is related with my bridge settings, cause I have a two
internal network(10.0.0.0/24, 10.0.1.0/24) bonding to the same
interface(em2)

What step should do to finger out what's going on?
