I used the following command: virt-install --connect qemu:///system -n server -r 512 --vcpus=1 -f kvm/server.cyberteams.com/root.qcow2 -s 12 -c iso/CentOS-5.6-x86_64-bin-DVD-1of2.iso --vnc --noautoconsole --os-type linux --accelerate --network=bridge:br0 --hvm which with a BlueOnyx CD some months ago worked fine. However when I connected with virt-viewer, after going through the TEST function it then claimed it could not find the CD. Is CENTOS a bit strange in some way?
