[Xen-devel] How to get machion address by pseudo physical address of guest OS
Hi everyone. What I talk below is in VMM level. I got a pseudo address of guest OS, how can I get the machion address? I mean I want to get the content in that address of memory. There maybe some functions to do this work, does anyone knows? Thanks. 2010-05-11 michael _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I don''t think the mapping is exposed to HVM domains at all. J _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
