Hi David Lutterkort asked me to send this patch to the list so it could be reviewed. What this small patch does is, it adds two functions to call "virDomainAttachDevice" & "virDomainDetachDevice" which allow devices to be attached & detached at run-time. The Ruby methods are called "attach_device" & "detach_device" and belong to the Domain class.
