Thanks! This is works fine. Last question - does it possible to create empty cdrom with type='network'? I'm try this, but libvrit complains with error: <disk type='network' device='cdrom'> <driver name='qemu' type='raw'/> <target dev='sdb' bus='scsi' tray='open'/> <address type='drive' controller='0' target='1' bus='0' unit='1'/> <readonly/> </disk>

No, unfortunately not because "virsh change-media" wouldn't be able to convert its argument to the required libvirt XML. I think you would need a new virsh change-media option, e.g. --xml, that takes a <disk> element instead of a source path + target path pair. However, I am not a libvirt developer. Paolo
