Hi, need help with koan when I use hvm virt type. On cobbler server I launch following commands: cobbler system add --name=virttest --mac=[mac address of eth0 on cobbler server] --profile=Centos5-x86_64 --virt-type=xenfv cobbler sync Then on client I launch this command: koan --server=[IP address of eth0 on cobbler server] --virt --nogfx --system=virttest --virt-name=vm02 I can see this: - looking for Cobbler at http://192.168.0.52/cobbler_api - reading URL: http://192.168.0.52/cblr/svc/op/ks/system/virttest install_tree: http://192.168.0.52/cblr/links/Centos5-x86_64 libvirtd (pid 2531) en cours d'exécution...
