Description of problem:
when I create the guest with the following script:

virt-install \
--connect qemu:///system \
--virt-type kvm \
--name demo \
--ram 500 \
--disk  path=/home/hongqing/testscript/demo.img,size=10,sparse=true \
--accelerate \
--location ftp://download.englab.nay.redhat.com/pub/fedora/linux/releases/14/Fedora/x86_64/os/ \
--channel tcp host=127.0.0.1:6080  mode=connect target_type=virtio  name=org.fedoraproject.anaconda.log.0


Version-Release number of selected component (if applicable):
Compiled against library: libvir 0.8.3
Using library: libvir 0.8.3
Using API: QEMU 0.8.3
Running hypervisor: QEMU 0.13.0

How reproducible:

Steps to Reproduce:
1. yum groupinstall virtualization
2. start the listening rsyslogd process on the host, using the analog script described below: 
   eval `scripts/analog -p 6080 ./ -o rsyslogd.conf -s`
3.run the script
  
Actual results:
console output is below:

Expected results:

mode=bind should be *mode=connect* , service =6080
