This is one of the reasons we no longer launch hotplug scripts from udev in xl, it is difficult to synchronize the process, and this kind of races can happen easily, I guess the same can happen in xend. I think the best way to fix this would be to switch to Xen 4.2 and the xl toolstack. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
