I have no idea where that message is coming from. Sounds like a challenge for someone who knows more about xenbus/xenstore. :-) -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Sometimes uuid/domid entries for dom0 for example, especially after domain destruction. The refresh/reaper is probably a bit too eager :( I think part of the problem is that currently xend uses a mixture of xstransact style state and xsobj and friends to store information. I don''t understand the xsobj stuff enough to debug this (Christian is aware of this) rolf _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
