Hi, When I call "xm setpolicy ACM test" command, xen returns this error: ACM policy type not supported I checked the code in /usr/lib/python2.5/site-packages/xen/xm/setpolicy.py and found that the error message is poped at line 131 # Non-Xen-API call. if xs_type != server.xend.security.get_xstype(): raise security.XSMError("ACM policy type not supported.") That means, at first, the server type is not "Xen-API", then function server.xend.security.get_xstype() returns 0. If I call "xm getpolicy" command, xen told me that the supported policy type is "None". My XEN version is 3.4.2,could anyone tell me why this error occured? Thanks. 2010-09-08 Best wishes Ruozeng W _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
