Comment 2 for bug 668043

Hi there,

I'm hitting the same bug with an explanation there :
http://www.spinics.net/lists/kvm/msg42207.html

libvirt "faulty" change :
http://libvirt.org/git/?p=libvirt.git;a=commitdiff;h=fd5b15ff1a2ec37e75609c091522ae1e2c74c811

and a quick way to test issue:
# /sbin/iptables --table mangle -A POSTROUTING --out-interface virbr0 --protocol udp --destination-port 68 --jump CHECKSUM

iptables v1.4.4: Couldn't load target `CHECKSUM':/lib/xtables/libipt_CHECKSUM.so: cannot open shared object file: No such file or directory

-------- Work around .....

.... Downgrade libvirt to 0.8.2 should let us use kvm with virt-manager ....
