Yes, libxl needs some modifications in order to execute hotplug scripts for block devices on FreeBSD. If you take a look at tools/libxl/libxl_freebsd.c:libxl__get_hotplug_script_info you will see that hotplug scripts are only executed if the device is a nic. I will try to craft a patch tomorrow to enable the execution of disk hotplug scripts for FreeBSD. Also, if you run xl with "-vvv" you will get a lot more of debugging info which might be helpful. Since there are no block hotplug scripts for FreeBSD yet there's no description about how parameters will be passed. I will also send you the calling convention and what is expected to be filled by the hotplug script upon execution together with the patch. Thanks, Roger. _______________________________________________ freebsd-xen@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to "freebsd-xen-unsubscr...@freebsd.org"
