[libvirt] attach device on a defined (non-active) vm

[Stefan de Konink]

It seems that the attach device function really 'attaches' a (live) 
device to a non-active domain. Is this by design?

Otherwise I would not have a clue how to interpreted this message:

libvir: Xen Daemon error : POST operation failed: (xend.err 'Device 
/dev/xvdp (51952, tap) is already connected.')

(when I try to start the domain)


So what I did; I have created an empty domain without any devices. 
Loaded that and added a disk.
