[libvirt-users] virt-install with --channel option inquiry

hi, virt guys, This is Hongqing from Fedroa QA team. I try to forward the guest installation logs to host with virtio. I have used virsh edit <guestName> to add a channel, it works fine. I think it would be better if I can initialize it when I create the guest using virt-install, and virt-install also offers the option, I have tried below, but it does not work. virt-install --connect qemu:///system \ --virt-type kvm \ --name demo2 \ --ram 500 \ --disk path=/home/hongqing/testscript/demo2.img,size=10,sparse=true \ --accelerate \ --cdrom /home/hongqing/fedora/Fedora-14-x86_64-DVD.iso \ --channel tcp host=127.0.0.1:6080 mode=connect target_type=virtio name=org.fedoraproject.anaconda.log.0 error message is : ERROR internal error Process exited while reading console log output: char device redirected to /dev/pts/20 getaddrinfo(127.0.0.1,None): Servname not supported for ai_socktype chardev: opening backend "socket" failed both the host and guest are fedaora 14. I have checked the service syslog with port 6080 is listening. and also I have disabled the SElinux. Do you have any idea about this? Thanks for taking time to view it. Hongqing YANG
