Hi, Just remove the <source> element from cdrom device and it should work even for xen. This will work, but is this the correct way? I din't remove soure attribute from config file for esx and kvm after installation, but there i had no issues. Can we control citrix xen server with libvirt ? If so, can you provide me the links for documents.
