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.

hi,
i''m a real Xen user since version 2.0.7 and i still believe on the
power
and charme from Xen. I used Xen for my costumers, for my own and I''m
proud to tell everybody about Xen, what they can do with the hypervisor
and i''ve written severals German HOWTOs. But, where the sun is, the
shadow isn''t far away: Xen lacks absolutely on actual docs. The
ManPages
are still not updated (many FIXME), not all parameters are listed in
(5), for example
cpu_cap and cpu_weight? How can i define it in a DomU config? (i know
it, now)
another example:
"dom0-min-mem" is listed, but where is "enable-dom0-ballooning
yes" ?
Take a look, what you have with "xm help" and what you get in the
manpage.
At this time, i have to read the sourcecode, to know, what this means.
Xen has so many features, but without good manpages, nobody knows about
them. Also the ("make -C docs") the documentation in the Xen source
code, is more for developers (and still to old too), than for new users.
They better searching with Google for HowTos.
So, why it is so hard to take some time for a good documentation,
instead of developing new features, where nobody knows,that they exists,
if they don''t read the source code or the mailinglists?

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
