Hi, In domU, we can''t use xenbus to access anything outside of the domain''s home. That means we are being restricted from reading/writing to other domain''s xenstore. That is perfectly fine, and nobody complains here. But in dom0, do we have the exception? Since dom0 is trusted, I think we can be allowed to access to all other domU''s xenstore. Is that possible? If not, any good workaround solution? Thank you. Hieu _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

If you specify a path without a ''/'' in the beginning, it defaults to reading from the domain''s home directory. However, if you use a fully qualified path, you should be able to read anywhere. If this doesn''t work, it''s a bug.
