[libvirt-users] Error connecting to console

Hi, i have KVM running at the moment and im trying to do a text based install of centos, so i need to connect to the console via virsh virsh console servername but i get this error: error: Failed to get local hostname How do i resolve this issue to get a consol connection to the server? I have tried to put it into the /etc/hosts file, but to no avail. Hope someone can help or suggest another method of doing a headless and X less install of a guest? Kind Regards Tony
