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

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.

Re: [Xen-devel] "Hello Xen Project" Book.
Thank you so much. Finally, we see that someone thinking about beginners. In my idea Linux Foundation must support this project.

I would like to make the book available to the Xen Project under a CC-BY-SA-3.0 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.

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. -George ___ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel

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. -George ___ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel

Re: [Xen-devel] Xen Development for Dummies.
Thank you. Can you answer my previous questions about Ocaml and C? Why Ocaml is unique and which part of Xen use it? I know my questions are silly but I'm a dummies and I looked at amazon.com and found Tons of C book but which one is good? Cheers.

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. -- Pasi > Cheers. > > > > On Friday, February 6, 2015 2:46 AM, Pasi Kärkkäinen wrote: > On Fri, Feb 06, 2015 at 10:31:09AM +, Jason Long wrote: > > Can you tell me why Ocaml used?

Re: [Xen-devel] Xen Development for Dummies.
In your opinion, Can a normal user like me become a developer? I must first start learning C or Ocaml? Can you recommend a book for both to me? Can you tell me why developers choose Ocaml and C? and not C++ or Python? Cheers.

Re: [Xen-devel] Xen Development for Dummies.
Can you tell me why Ocaml used? What is the features of this language? Why not other? Excuse me, I'm a beginner in programming and can you show me some books or reference step by step?
