Hi,

Look under examples:
http://builder.virt-tools.org/artifacts/libvirt-virshcmdref/html/sect-attach-disk.html

(root@h2)-(/)# virsh attach-disk vps_99 /dev/nbd2 vdb --address pci:0000.00.11.0 --persistent
error: command 'attach-disk' doesn't support option --address

(root@h2)-(/)# virsh --version
0.7.5

Is someone playing a trick on me?

Regards,
Daniele
