Hi, Can anyone please tell me how to get ".probe" function in "struct xenbus_driver" called? I want to do one simple test of event channel communication between peer modules of domU and dom0. I wrote one backend and one frontend driver (I tried registered as misc/blk/input device) where I put in all my xenbus routines, but cannot get .probe called after insmod my module, I

I'm using R embedded in PostgreSQL (via PL/R), and would like to use it to create images. It works fine, except that I have to create every image in a file (owned by and only readable by the PostgreSQL server), and then use PostgreSQL to read from that file and return it to the client. It would be much nicer if I could plot images into an R variable (for instance, a matrix), and return that

Hi, I have been able to run 32 bit virtual machines on a 64 bit machine quite nicely with xen3.1 but sometimes when running yum the messages "do_wp_page: bogus page at address 0070d638" and "kernel: VM: killing process yum" and yum just stops working. I also get Kernel Panic. Does anyone have any idea, what could be the probem? Thanks, Ricardo

Directly including ../tools breaks building in separate object tree, as well as building from mkpatch patch (I believe Rik hit that one). This puts xenstore headers in linux-public.

Hi I have a few questions regarding CPU frequency scaling in xen.. 1) Is CPU frequency scaling allowed in xen? especially in xen3.1 ? 2) If no, what are the reasons for not allowing ? 3) If yes, why is it disabled? And how to enable it ? 4) I think there are some patches available for providing this support. Are there any reasons for not including this patches in official release of xen?
