Hi, tinnycloud:
Could you use dump_execution_state() in mm.c:859? And in the unshare() function, could you move the printk outside the (!p2m_is_shared(p2mt)) checking? If you put inside it, we never know if the unshare() is being done or not (please also print out the mfn, p2mt, gfn, domain_id). Just out of curiosity, are you running stubdom? your HVM guest id =2 is pretty weird. Thanks, Jui-Hao _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
