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

This seems like a bug in XenD to me - when attaching a disk we simply pass the SEXPR config straight into XenD's device_create RPC call. If it accepts it without error, that's pretty much where libvirt's involvement ends. So if it doesn't subsquently start there's something wrong with XenD - either it failed to reject an invalid config when libvirt made the device_create call, or it otherwise broke the guest in some way.
