I copied the <STRONG>void memdump_gvirt(u64 gvirt) </STRONG>fuction in "process/debug.c", but it always returned a <STRONG>VMMERR_PAGE_NOT_PRESENT </STRONG>value to me, so I want to know is this func really works, or how could I use the func to convert a gva? And if it doesn't work, would you mind giving me some advices to finish this func? By the way, my enviroment is bitvisor 1.3 with 64bit Ubuntu 12.04.<STATIONERY> <DIV> <STYLE type=text/css> body {font-size:10.5pt; font-family:微软雅黑,serif} </STYLE> <META name=GENERATOR content="MSHTML 8.00.7601.17514"><STATIONERY> <DIV><SPAN style="FONT-FAMILY: 微软雅黑; COLOR: #000000; FONT-SIZE: 10.5pt"></SPAN> </DIV> <DIV><SPAN style="FONT-FAMILY: 微软雅黑; COLOR: #000000; FONT-SIZE: 10.5pt">Thanks & <BR>Best Regards,<BR>Augustus Liu(刘丹珂)<BR>======<BR>E-Mail:hikkikuma1991@163.com</SPAN></DIV></DIV></DIV></BODY></HTML>
