I noticed that when you kill xenstored in xen-unstable.hg 8758, it will take down all of domain 0. Killing xenstored is probably not the smartest thing to do, but it shouldn''t take down dom0.

As of yesterday, changeset 8777:581d4a0ac729, this bug is still there. It''s in bugzilla as bug #520: http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=520 Thanks, Paul Larson _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
