When I was chasing down a similar problem back in August, I discovered that Dom0 accesses XenStore through a unix domain socket and not through the kernel interface, so hitting it through xenstore-ls always seemed to work. That is why Dom0 reads/writes to XenStore ok with the same kernel that fails for your DomU. When I moved XenStore to a stubdomain, I /did/ see the problem in Dom0 with new enough kernels, which is why the XenStore access library was changed to prefer the dev device instead of the proc file. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
