Hi I seem to be having a little trouble with libxenstat, and was wondering if the xenstat guys might be able to help. I''ve pulled the xen-unstable.hg tree and done a somewhat clean install (ie, post-make uninstall, as well as deleting the relevant libxenstat libraries). Next, I entered the tools/xenstat/libxenstat directory and modified the Makefile so that the shared libraries would be installed. I''ve included my Makefile below. I ran: make make install make python-bindings make install-python-bindings Next, I started a python session and entered: import xenstat and got the following output.> Python 2.3.5 (#2, Sep 4 2005, 22:01:42) > [GCC 3.3.5 (Debian 1:3.3.5-13)] on linux2 > Type "help", "copyright", "credits" or "license" for more information. > >>> import xenstat > Traceback (most recent call last): > File "<stdin>", line 1, in ? > File "/usr/local/lib/python2.3/site-packages/xenstat.py", line 5, in ? > import _xenstat > ImportError: /usr/local/lib/python2.3/site-packages/_xenstat.so: undefined symbol: xenstat_init >Any thoughts?

It''s in the tree for xentop. It may play a larger role in future versions but for right now it''s function is pretty limited. You may have better luck using the xc python bindings that are installed with Xend. You can get the same information as you can get in libxenstat just through a different interface. In xen.lowlevel.xc, you want to use domain_get_info() and domain_get_vcpu_info().

If so, you can either add /usr/local/lib to the default search path by editting /etc/ld.so.conf, or you can install into the prefix /usr which will put the libraries in /usr/lib. Also, as Anthony pointed out, keep in mind that xenstat will not be an officially supported public interface in Xen 3.0. It may become such an interface in the unstable tree after 3.0 is released. However, don''t let that stop you from making use of it, and feel free to ask if you need any additional assistance. - Josh Triplett _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
