Or UUID, for that matter. Ideas? Use relative paths: code10:~ # xenstore-read vm /vm/0fa9cb1b-1275-7027-9cab-80089db40ed4 code10:~ # xenstore-read domid 1 That's it. But adding a watch for these doesn't work (at least it didn't last time I tried), so you can't easily get notified in case the domid changes due to migration or save/restore. cheers, Gerd -- Gerd Hoffmann <kraxel@xxxxxxx> Erst mal heiraten, ein, zwei Kinder, und wenn alles läuft geh' ich nach drei Jahren mit der Familie an die Börse. http://www.suse.de/~kraxel/julika-dora.jpeg _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
