IOW, raise an error now, and remove the > error in a later patch. Ack. So in total there should be 3 checks right. 1) if 'has_channels' is set, 2) if 'uri' and 'channels' both are present, 3) if 'uri' and 'channels' both are absent. Basically right now only uri should allowed and should atleast be present. I think overall only 1) would be enough and should be checked before 'migration_channels_and_uri_compatible()' and if 'has_channels' is set, just return for now. With this 2) would not be necessary or not come into play in this patch. 3) will be taken care by 'migration_channels_and_uri_compatible()' itself IMO. Let me know if I am missing something here. >> >>> @@ -1694,6 +1708,16 @@ void qmp_migrate(const char *uri, bool has_blk, bool blk, >>> MigrationState *s = migrate_get_current(); >>> g_autoptr(MigrationAddress) channel = g_new0(MigrationAddress, 1); >>> >>> + /* >>> + * Having preliminary checks for uri and channel >>> + */ >>> + if (uri && has_channels) { >>> + error_setg(errp, "'uri' and 'channels' arguments are mutually " >>> + "exclusive; exactly one of the two should be present in " >>> + "'migrate' qmp command "); >>> + return; >>> + } >> Same here >> >> >> With regards, >> Daniel >> -- >> |: https://urldefense.proofpoint.com/v2/url?u=https-3A__berrange.com&d=DwIDaQ&c=s883GpUCOChKOHiocYtGcg&r=-qwZZzrw4EKSsq0BK7MBd3wW1WEpXmJeng3ZUT5uBCg&m=i0lmmIrs7N4r3uqLYCdRVXLFaEavt77Ltkec0hIlE4aUQITo9-8povsDHWELv-vE&s=AQ1C7WPg2jLYjNXU29Xw7trQcjmB96Yy3-God3-UaIQ&e= -o- https://urldefense.proofpoint.com/v2/url?u=https-3A__www.flickr.com_photos_dberrange&d=DwIDaQ&c=s883GpUCOChKOHiocYtGcg&r=-qwZZzrw4EKSsq0BK7MBd3wW1WEpXmJeng3ZUT5uBCg&m=i0lmmIrs7N4r3uqLYCdRVXLFaEavt77Ltkec0hIlE4aUQITo9-8povsDHWELv-vE&s=aiGUx76ySVL-epTmaFIZUyZbkzeXGedVaXGvFw4xcgo&e= :| >> |: https://urldefense.proofpoint.com/v2/url?u=https-3A__libvirt.org&d=DwIDaQ&c=s883GpUCOChKOHiocYtGcg&r=-qwZZzrw4EKSsq0BK7MBd3wW1WEpXmJeng3ZUT5uBCg&m=i0lmmIrs7N4r3uqLYCdRVXLFaEavt77Ltkec0hIlE4aUQITo9-8povsDHWELv-vE&s=beFwppzRJ_eYlYPZKHlSZpaysLC5AExPh5_inAZBu_k&e= -o- https://urldefense.proofpoint.com/v2/url?u=https-3A__fstop138.berrange.com&d=DwIDaQ&c=s883GpUCOChKOHiocYtGcg&r=-qwZZzrw4EKSsq0BK7MBd3wW1WEpXmJeng3ZUT5uBCg&m=i0lmmIrs7N4r3uqLYCdRVXLFaEavt77Ltkec0hIlE4aUQITo9-8povsDHWELv-vE&s=q6fb1PbChin197qfXnyXa1FpzaC7GecQJOzWO1EUQTo&e= :| >> |: https://urldefense.proofpoint.com/v2/url?u=https-3A__entangle-2Dphoto.org&d=DwIDaQ&c=s883GpUCOChKOHiocYtGcg&r=-qwZZzrw4EKSsq0BK7MBd3wW1WEpXmJeng3ZUT5uBCg&m=i0lmmIrs7N4r3uqLYCdRVXLFaEavt77Ltkec0hIlE4aUQITo9-8povsDHWELv-vE&s=lUJpjpbEMjPFyDvx1GXWR5yrxWfQqTyLI42J5oxavgs&e= -o- https://urldefense.proofpoint.com/v2/url?u=https-3A__www.instagram.com_dberrange&d=DwIDaQ&c=s883GpUCOChKOHiocYtGcg&r=-qwZZzrw4EKSsq0BK7MBd3wW1WEpXmJeng3ZUT5uBCg&m=i0lmmIrs7N4r3uqLYCdRVXLFaEavt77Ltkec0hIlE4aUQITo9-8povsDHWELv-vE&s=u9HElHtI7mdNiWq8I7j1GpnUObfjfopMmpLdvGZRI8k&e= :| >> >> > With regards, > Daniel Regards, Het Gala
