[Xen-devel] VMWare and Linux Foundation.

[Jason Long]

Hello.
VMWare become a gold member of LF and I want to know can it a danger for Xen 
Project and Citrix XenServer? Xen Project and Citrix XenServer are competitor 
for VMWare and became a gold member of LF can cause any problem? 


Thank you.

Re: [Xen-devel] [Xen-users] "Hello Xen Project" Book.

[Jason Long]

It is a good news and I hope Xen experts thinking about beginners like me. Xen 
is great but have some problems in documenting and easy to use. I hope to see 
this book on Xen Project website soon.

Thank you Xen team.

 Hi all,
 I had a go at converting the first

 And https://wiki.xenproject.org/wiki/Book/HelloXenProject/0-Contents
 All relevant information for people to

 Juergen, thanks for the tip. I
 installed an openSUSE VM and the libreoffice-wiki-publisher
 came as default, which is good. So I ran a few tests.
 
 First, what I couldn't get to
 work: I tried Send > MediaWiki in the hope that this
 would allow transferring of images, but could not get it to
 work. There seems to be an issue with authentication on the
 XenProject wiki side. But File > Export [MediaWiki
 (.txt)] works. 
 
 Also, I couldn't find
 any docs for the converter: the help links to pages which do
 not exist. But hey, we can live with that.
 
 Here is what I learned:
 ===
 * The export granularity
 is 1 LibreOffice document to 1 Wiki Page
 * Most of the basic formatting such as
 lists and tables get correctly converted, but the converter
 introduces an awful lot of ... and ... attributes.
 Basically it does this every time, something slightly out of
 the ordinary has been done with text. These may have to be
 stripped with on-line tools such as 
http://www.unit-conversion.info/texttools/strip-tags/
 or similar, otherwise the wiki pages become a nightmare
 to edit in future.
 *
 URLs are correctly converted
 * Headlines (aka text marked as
 "Heading 1", "Heading 2", etc. are not
 converted) to = ... =, == ... ==, etc.
 * Images are not converted: when an
 image is found, "[[image:|top]]" is inserted
 * I don't know how
 code snippets will come across in terms of formatting, as I
 don't have the ODT source of the book
 
 What does this mean:
 
 In principle, this means that should
 be doable with 1-2 days worth of work. However it's not
 going to be entirely trivial. What we would need to do is
 to:
 * Break the
 original book ODT file into smaller sections (probably along
 the chapter structure as exposed in the Contents)
 * Then take each of the
 ODT files and do the following
 ** Save as MediaWiki (.txt) [1]. If
 appropriate remove tags using 
http://www.unit-conversion.info/texttools/strip-tags/
 ** Save as html [2] - to
 get the images. The bad news is that the images are saved
 using some hash names and not in the order they are in the
 document
 ** Create the
 wiki page from [1]
 **
 Fix up bad formatting (such as missing = ... =, == ... ==,
 etc.)
 ** Manually
 upload the images from [2]
 ** Add appropriate [[Category:...]]
 tags at the bottom of each page. At least one for the
 wiki-book, e.g. [[Category:HelloXenProjectBook]] or
 something similar. But of course further categories per
 topic can be added as needed.
 
 Once we have all the content, create
 the common pages such as contents, credits, etc. - and we
 should have a good starting point.
 
 Best Regards
 Lars

Thank you so much.
Finally, we see that someone thinking about beginners.
In my idea Linux Foundation must support this project.

 license. Ideally, I would like to publish the content on the
 Xen Project wiki in an editable form, such that others can
 contribute and build on it and it stays up-to-date. I also
 noticed that the Xen Wiki has the 
https://www.mediawiki.org/wiki/Extension:Collection
 extension, which should make it possible to create a
 PDF, ODF or DocBook from the pages for those who want a
 manual rather than wiki pages.
 
 Thank you for doing this. As far as I can tell the fact that
 you published the book under CC-BY-SA-3.0 would make it
 possible to move the content to the wiki. 
 
 > I had a conversation with Lars to check whether this is
 possible and he believes it is. He suggests that first we
 upload the book as pdf to the wiki and as a second step,
 agree an information architecture and then convert the book
 to mark-down. There are a number of conversion tools which
 should get us there some of the way, with a bit of cleanup
 and beautification needed after the initial import. I can
 make the source available in a format that makes conversion
 to markdown easier.
 
 We do need to find a way to convert the content into
 markdown format though, which may be quite a bit of work.
 
 I have done this before for html pages, converting them into
 docman markdown. I have not checked whether there are online
 or command line tools which do that for mediawiki markdown.
 In any case, the conversion is fundamentally doable,
 although it will be somewhat tedious to do this. If anyone
 has more experience, please share and advise what the best
 way forward is.
 
 The main problem that I faced when doing something similar
 were tables, figures and other more advanced formatting.
 Much of this may get lost or "corrupted" in some way and
 will have to be re-introduced post conversion.  
 
 @Mohsen: as far as I recall, you used Word or LibreOffice to
 create the book? Is that correct? If so, it should be
 possible to save it in html, which would ensure that figures
 and so on are saved in some sensible way. We would probably
 need to find a temporary location where to store this. And
 we can start experimenting a little and maybe provide a
 quick guide on how to do this.
 
 As for the information architecture, I was thinking about a
 structure such as ...
 
 https://wiki.xenproject.org/wiki/ 
 https://wiki.xenproject.org/wiki//title_and_credits
 
 https://wiki.xenproject.org/wiki//
 
 https://wiki.xenproject.org/wiki///
 
 ... a separate article for each article in the book, such as
 "Virtualization and Security". As a first step, we would
 probably keep the original chapter structure. 
 
 This would then look something like ...
 https://wiki.xenproject.org/wiki/HelloXenProject
 https://wiki.xenproject.org/wiki/HelloXenProject/0/Title
 https://wiki.xenproject.org/wiki/HelloXenProject/0/Credits
 https://wiki.xenproject.org/wiki/HelloXenProject/0/Licence
 https://wiki.xenproject.org/wiki/HelloXenProject/1-Intro
 https://wiki.xenproject.org/wiki/HelloXenProject/1-Intro/History
 https://wiki.xenproject.org/wiki/HelloXenProject/1-Intro/TypesOfVirtualization
 
 We may need some other extensible numbering scheme, which
 would make it easy to create PDF's with 
https://www.mediawiki.org/wiki/Extension:Collection -
 again, this is something I don't have experience with.
 
 > What do people think? Is this a good idea? Would anyone
 be willing to help? I am not very familiar with Markdown and
 would need someone else to help with the wikification of the
 book. Lars already volunteered to help.
 
 I will definitely help, but this would be an activity, which
 could easily be distributed. So help from others would be
 very highly appreciated.

That is all good, but the development on it seems to have stopped (no checking

Anyhow I am still confused what you are asking for? Is it the idea of hosting

Well, sure. A full-fledged program like kernelnewbies is way more than
that, and is not easy to put together.

For what it's worth, we already try to participate to programs like
Outreacy and GSOC, but certainly we can improve some of the sections of
our wiki with what you say in mind --e.g., the one(s) when we try to
keep a list of small projects.

I'll try to find some time to look into this and do something.

Thanks for your interest and suggestion.

 I don't think it's
 quite the right thing and what Geze is looking for. I
 think it's more about, which books, where
 do you find API docs/design
 docs/..., how to
 build/test/troubleshoot, etc. - I think we have a lot of
 this all over the place with a few gaps.
 
 I think the challenge is that
 what we write down would need to make sense
 for a newbie. So it would have to be
 A) written by someone else - tested by a
 newbie
 B) written by someone who is just
 getting started, e.g. someone starting
 on
 Outreachy
 
 @George: this
 could be something which may be worthwhile discussing
 with
 Rojas

 I don't think it's
 quite the right thing and what Geze is looking for. I
 think it's more about, which books, where
 do you find API docs/design
 docs/..., how to
 build/test/troubleshoot, etc. - I think we have a lot of
 this all over the place with a few gaps.
 
 I think the challenge is that
 what we write down would need to make sense
 for a newbie. So it would have to be
 A) written by someone else - tested by a
 newbie
 B) written by someone who is just
 getting started, e.g. someone starting
 on
 Outreachy

[Xen-devel] Define a new Wiki part for Xen Project.

[Jason Long]

Hello developers.
I have a request and please let me know your idea.
Can Xen experts define a new part on Wiki about Xen developing for beginners? I 
mean is something like "
kernelnewbies.org" but for Xen. For example, say to users which programming 
languages are necessary, which book is good for learning those languages and 
which part of Xen codes are good for start.
I know it may funny for someone here or smeone consider the questions like it 
as Spam but be sure it help begginers and other users for improve Xen and get 
involved to project.
I like to hear developers idea.

Thank you.

 Thank you but I guess it is serious

 Are you Sure Red Hat company help Xen? I guess you wrong.
 Red Hat employee not mean Red Hat company and they can help
 other Open Source projects as hobbyist. I guess some Citrix
 guys help KVM as hobbyist too. When you read Virtualization
 books then all of them explain VirtualBox and VMWare
 Workstation but why not Xen? It is because of a GUI leak. In
 my opinion, Xen and Citrix guys must work on a nice
 interface for Xen and don't thinking about something like
 virt-manager or..

 To corroborate this, two points:
 
 First, RedHat generally do Open Source properly: They run
 projects
 like virt-manager and libvirt as proper open-source
 communities, even
 when their engineers are doing the lion's share of the
 work.
 Obviously the RedHat engineers focus on functionality which
 is
 important to RedHat.  But it's been my consistent
 experience that
 these projects accommodate work that people from the 
 Xen community
 put in.  The libvirt guys don't actively develop Xen
 functionality for
 libvirt, but if we submit patches they get constructive
 review, and if
 someone else breaks existing Xen functionality they fix it.
 
 Secondly, while Citrix doesn't use virt-manager for Xen,
 SuSE and
 Oracle do (I believe).
 
 If you know of bugs or deficiencies in virt-manager's Xen
 support,
 then please do report them.  But don't dismiss it
 out-of-hand simply
 because RedHat are the main contributors.

virt-manager is also available for Fedora and Fedora doesn't have a
problem with Xen.

virt0manager.org is registered to an individual (admittedly, I believe,
a Red Hat employee).   According to the home page it's available for
Fedora, Debian, Gentoo and OpenBSD.

You could go ahead and do your own version of a GUI but I'd suggest that
fixing the Xen interface and pushing any needed changes to libvirt would
be better.

I'm working with XenServer too and XenServer is not a complete Linux and you 
can't work it well like Linux. You can Install Xen on your Linux and doing

Have you tried XenServer? That is Citrix's product and has a well-liked GUI. 
Why would we want another one?

Re: [Xen-devel] Xen like VirtualBox

[Jason Long]

I see you are a Citrix Employee and you and your coworkers must help Xen. I 
guess start a dedicated GUI project for Xen help Xen users like me a lot. It is 
mandatory and if you see that some users use VirtualBox is it because of its 
nice GUI and not performance.

That's not really accurate. Virt-manager is --at least last time I've
tried, which is not too long ago-- a GUI front-end for libvirt.

It is may be true that a lot of its contributors works for or are
related to RedHat, and it is probably still true that it does its best
with KVM... But it actually works with Xen already (it, at least up to
a certain extent, should work with whatever uses libvirt).

In fact, if you go to https://virt-manager.org/ , this is what you
find:
"The virt-manager application is a desktop user interface for managing
virtual machines through libvirt. It primarily targets KVM VMs, but
also manages Xen and LXC (linux containers)."

It could be made a lot better, when used on Xen, but that will only
happen with some effort, and helping us assessing what does work and
what does not, would be a very valuable contribution.

Mmm.. so, you're saying that you like VirtualBox's GUI but you don't
like virt-manager's one, right? In which case, oh, well...

Personally, I think that, rather than developing something from
scratch, it would be a lot better to use virt-manager
(https://virt-manager.org/), or other similar front-ends.

About virt-manager, it is built on top of libvirt, and Xen support in
libvirt has improved a lot during the past couple of years. Thath means
a bunch of things and features actually work already.

It would be really nice and useful if someone could actually try and
use it with Xen, and report here and to the libvir and virt-manager
communities what is missing/not working.

[Xen-devel] How to install Xen on Fedora 23?

[Jason Long]

Hello.
I installed Fedora 23 x64 on my PC and id below command for installing Xen :

# cd /etc/yum.repos.d/
# wget http://fedorapeople.org/groups/virt/...t-preview.repo
# yum update
# yum -y install xen xen-hypervisor xen-libs xen-runtime
# systemctl enable xend.service
# systemctl enable xendomains.service

After it I run below command :

# grep ^menuentry /boot/grub2/grub.cfg | cut -d "'" -f2
Fedora (4.4.7-300.fc23.i686) 23 (Workstation Edition)
Fedora (4.2.3-300.fc23.i686) 23 (Workstation Edition)
Fedora (0-rescue-204e260309794cee901bd6e0b46ace3a) 23 (Workstation Edition)

But, I can't see any "Fedora, with Xen hypervisor" !!! and when I run "xl info" 
it show me below error :

# xl info
xc: error: Could not obtain handle on privileged command interface (2 = No such 
file or directory): Internal error
libxl: error: libxl.c:114:libxl_ctx_alloc: cannot open libxc handle: No such

cannot init xl context

How can I solve it?

Thanks for you enthusiasm. I don't think knowing how to program is a
must-have for testing Xen (or any software in general). What is needed
is the ability to follow instructions, produce useful bug reports and
communicate clearly.

We have some wiki pages on related topics.

http://wiki.xenproject.org/wiki/Xen_Project_Beginners_Guide
http://wiki.xenproject.org/wiki/Reporting_Bugs_against_Xen_Project
http://wiki.xenproject.org/wiki/Xen_Project_Best_Practices

Hope this helps.

Xen hypervisor, like any other hypervisor, is a very low level piece of 
software.
Lowlevel software tends to be written in lowlevel languages, such as C and 
assembler.

Like said most of Xen is written in C, so you need to learn/know C.

You should first start with learning programming with C language, and the 
generic concepts of computer hardware,
operating systems, kernels, memory management, etc.

Something like a hypervisor, or an operating system kernel, is a quite complex 
beast,
so you should probably first start with something much easier and learn C 
properly in an easier project.
When you know C and Linux/Unix internals well you can continue working on Xen 
aswell.

 There are two different versions of xenstore-daemon (xenstored). 
 The earlier one, written in C, and the newer one, written in OCaml 
 (oxenstored).
 
 Note that this is just one of the many components in Xen. Most Xen components

  Hello,
  
  Xen is mostly written in C language, but there are other languages being 
  used aswell.. obviously lowlevel assembly language for some architecture 
  specific lowlevel stuff, and some highler level languages (OCaml) for 
  certain components (oxenstored). Also various scripting languages are used, 
  perl, python, etc. 
  
  Also you need to know all the usual Linux/Unix commandline (development)
