If you enable event delivery before registering a callback handler then your domain will crash on first event delivery. But then you would be restarted in a fresh domain with a new shared_info page; wou wouldn't jump back to the entry code of the existing domain. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
