Add per domain server features, which are initialized by the supported features at domain introduction, or by live update from the migration stream. This requires to add the DOMAIN_DATA record to the migration stream, but for now it will only contain the feature word. Advertise the Xenstore features to guests by setting the appropriate bits in the ring page. Signed-off-by: Juergen Gross <jgross@suse.com> Reviewed-by: Jason Andryuk <jason.andryuk@amd.com>
