Perhaps worth checking with a xenstore-ls -p, or a xenstore-write attempt within a domU, but the vm node should be owned by dom0 and read-only by the domU. The recent xenstore permissions fixes should ensure that. So the patch should be safe and if it's not it's a xend bug that needs fixing. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
