How do we probe the Xen hypervisor, while running as the dom0 (which is the GUI frontend for us, and running as guest)? Since the entry to hypervisor is controlled, I supposed it will need a patch before systemtap can be used to probe the Xen hypervisor, right? Or is it not a logical thing to do? My target of interest will be to trace/analyze the behavior of the Xen hypervisor, and the domX guest as well. Thank you for your answer. -- Regards, Peter Teoh _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

So far, no download yet. but I don''t see much of a difference in feature from systemtap, or perhaps I am totally wrong? -- Regards, Peter Teoh _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
