Denny: I appreciate your comments on the Xen documentation. I have been looking for people in the community to assist with updating or creating new documents. I have some people working on various documents but there is still no formal community effort. I am currently working on the new Xen Roadmap document and plan to start updating other documents once that is complete. If you are interested in working on something for the community please let me know so I can keep track of who is doing what. Thanks.

There is a huge bug in Xen that it is a pain in the neck to solve. In a production scenario, I set all DomUs to avoid using proc 0 (reserved for Dom0 exclusively). This is done, only, by using this trick Xm list --long NameOfDomU > NameOfDomU.sxp Edit NameOfDomu.sxp and add (cpus 1-X) after the vcpus line. Xm del NameOfDomU Xm new -F NameOfDomU.sxp The problem is that if you reboot the server, and Xen brings up all the VM''s listed in /etc/xen/auto, all this work is lost, it does not get preserved between reboots. If you have a large amount of DomU''s, you need to create your own starup script that basically goes over the list of DomU''s and does a "xm new -F name.sxp". Xen should preserve those changes automatically between reboots.

Any idea if online XVD/VBD disk resizing will end up in the roadmap? Some discussion about the subject: http://lists.xensource.com/archives/html/xen-devel/2008-09/msg00158.html Upstream Linux kernel currently supports online SCSI disk resizing, so it would be damn nice if Xen supported that too.. -- Pasi _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

What i said, i''ve written one of the biggest Xen HowTo in German (except for the books very good books from Henning Sprang (and Co) and Andrej Radonic), available on the web¹ and i know, how to write, so that most of the users understand. My problem is more, to get information about new functions and it is hard to read the source code, cause it lacks often in comments. So my magic sphere is often used. So, if you have a roadmap, tell me and i wish to help the community. everytime, i can spent work on it, i will do it. cu denny ¹ http://www.pug.org/mediawiki/index.php/Xen-installation _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
