Re: [libvirt] [PATCH alt] conf: Allow user define their own alias

https://bugzilla.redhat.com/show_bug.cgi?id=1434451 It comes handy for management application to be able to have a per-device label so that it can uniquely identify devices it cares about. The advantage of this approach is that we don't have to generate aliases at define time (non trivial amount of work and problems). The only thing we do is parse the user supplied tag and format it back. For instance: <disk type='block' device='disk'> <driver name='qemu' type='raw'/> <source dev='/dev/HostVG/QEMUGuest1'/> <target dev='hda' bus='ide'/> <alias user='myDisk0'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com&gt; --- An alternative approach to: https://www.redhat.com/archives/libvir-list/2017-September/msg00765.html Honestly, I prefer this one as it's simpler and we don't have to care about devices changing their aliases on cold plug. I mean, on cold (un-)plug we'd have to regenerate the aliases so it might be hard to track certain device. But with this approach, it's no problem. Also, I'm not completely convinced about the name of @user attribute. So I'm open for suggestions.
