Hi, if Xen''s kernel stack address is fixed? I print the esp value at the entry of exception handler and find that esp has fixed value. But Xen should support reentrancy, right? Then why it has fixed stack address ? Thanks, -- Xinxin _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

Because if you only ever look at the outermost exception (i.e. the trap from guest mode) the stack will indeed appear to be at the same address. Ian.
