Comment 2 Cole Robinson 2008-06-25 17:17:21 EDT
This does not seem to be specific to cd connect/eject: any domain redefinition
will wipe out any custom additions to the xm config, running or not. Anyways,
this is a libvirt issue. Updating the bug description and reassigning there.
Comment 3 Daniel Berrange 2008-06-25 18:33:37 EDT
This is expected behaviour. Any parameters in the config file not supported by
libvirt will be removed. Please file BZ feature requests for /each/ individual
parameter you require representation for, so their addition to the libvirt XML
format can be tracked.
