[libvirt] [PATCH]virsh: improve usability of '--print-xml' flag for attach-disk command

[Chen Hanxiao]

From: Chen Hanxiao <chenhanxiao at cn.fujitsu.com>

'--print-xml' option is very useful for doing some test.
But we had to specify a real domain for it.
This patch could enable us to specify a fake domain
when using --print-xml option.
