[Libvir] Release of libvirt-0.0.4
by Daniel Veillard 10 Feb '06

10 Feb '06

Change of name, it's now libvirt due to negative feedback on the shorter name, but I don't intend to change the mailing-list name at this point. There was an intermediary libvirt-0.0.3 release but it was too broken I needed to rerelease. Except the change of names, it mostly consists of a couple of bug fixes and completion of the python bindings. Available at ftp://libvirt.org/libvirt/ The CVS checkouts should still be working, the update is just a bit intrusive, and I fixed the hourly snapshot from CVS generation which broke in december. Sorry for the mess !

Hello, I have tried writing a simple program. I have compiled it with cc xmlist.c -L /usr/src/redhat/BUILD/libvir-0.0.1/src/.libs -lvir -o xmlist But am getting an error on trying after the virConnectOpen call . Any help would be appreciated . Rgds, Dakshina Here is the code :xmlist.c #include <stdio.h> #include <libvir.h> main(){ virConnectPtr conn; int *domids ; int maxids = 20; int numDoms=-1; conn=virConnectOpen(""); if(conn == NULL){ printf("Error : Could not open a connection \n"); return(-1); } numDoms=virConnectListDomains(conn,domids,maxids); printf("The number of domains %d\n",numDoms); printf("The number of domains %d\n", virConnectNumOfDomains(conn)); } cc xmlist.c -L /usr/src/redhat/BUILD/libvir-0.0.1/src/.libs -lvir -o xmlist Daniel Veillard <veillard(a)redhat.com> wrote: On Tue, Jan 24, 2006 at 08:46:07PM -0800, dasari dakshina wrote: > Hello Daniel, > Thanks so much for the info .I downloaded the Xen > 3 source and was able to compile without any issues. > Is there any link where I can look at simple examples > of the API usage ? not yet, check http://libvir.org/html/libvir-libvir.html Please keep discussion on the list, thanks, Daniel -- Daniel Veillard | Red Hat http://redhat.com/ veillard(a)redhat.com | libxml GNOME XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | Rpmfind RPM search engine http://rpmfind.net/ --------------------------------- What are the most popular cars?

[Libvir] Release of libvir 0.0.2
by Daniel Veillard 29 Jan '06

29 Jan '06

A new release is availble on libvir.org: The main change is the mode of operation for most function, now going though Xend HTTP remote procedure calls instead of hypervisor and xenstore operations. * Update of the documentation, web site redesign (Diana Fong) * integration of HTTP xend RPC based on libxend by Anthony Liquori * Adding Save and Restore APIs * extended the virsh command line tool (Karel Zak) * remove xenstore transactions (Anthony Liguori) * fix the Python bindings bug when domain and connections where freed Enjoy !

[Libvir] [PATCH] Remove XenStore transactions
by Anthony Liguori 27 Jan '06

27 Jan '06

XenStore transactions aren't actually needed for our current uses of XenStore. Moreover, the type of transactions changed recently from an opaque pointer to an integer type. This breaks the build for newer changesets. The change also introduced an XBT_NULL type but instead of using that (which would break older builds), we can just pass 0. Regards, Anthony Liguori # HG changeset patch # User Anthony Liguori <anthony(a)codemonkey.ws> # Node ID 9fe0c1f3379e06054ff66a572daad59bbfac3292 # Parent c028398d53b98baf08eb97192d599fbd311e3dd1 Remove transactions as the type has changed recently breaking the build and more importantly they aren't actually needed here. diff -r c028398d53b9 -r 9fe0c1f3379e src/libvir.c --- a/src/libvir.c Thu Jan 26 18:11:32 2006 +0000 +++ b/src/libvir.c Thu Jan 26 17:27:36 2006 -0500 @@ -307,7 +307,6 @@ */ int virConnectListDomains(virConnectPtr conn, int *ids, int maxids) { - struct xs_transaction_handle* t = NULL;

[Libvir] Persistent Configurations?
by Anthony Liguori 11 Jan '06

11 Jan '06

Howdy, Thought I'd try to start up a discussion on a topic that I know I've discussed a lot with people in the past. Xend currently stores its configurations in python files somewhere on the file system (usually in /etc/xen). This is problematic from a management tool perspective because the python files may contain arbitrary python code (requiring a python interpreter to read) and there's no central location which makes enumerating possible domains quite difficult. If you think about a typical use-case (or at least, my typical use-case :-)), a user is likely to have a larger number of domains than what are running (say a domain for a bunch of different distros for testing). It would be nice if any management tools could see those domains and easily start them up. I think we could achieve this with the following requirements: 1) Allow domain creation based on an opaque configuration object 2) Allow storing and retrieval of these configuration objects from the XenStore (using a user-specified path) I think this isolates the state well enough that it leaves the majority of the library stateless. Just some random thoughts... Regards, Anthony Liguori

[Libvir] ruby bindings
by Fraser Campbell 05 Jan '06

05 Jan '06

Hi, Is there any chance you are considering the addition of ruby bindings for libvir? I have been considering writing my own ruby wrappers around Xen's lowlevel libraries but if libvir is a higher-level more stable API perhaps it would make more sense for me to wrap around libvir. If you are not working on ruby bindings I will do so myself and eventually provide patches. Are you in a position to state yet whether libvir is likely to be continually developed and a key part of the Fedora/RHEL virtualization? I immediately see some missing functionality (migration), I assume the eventual goal is to support all features of Xen and that it is just missing because of the very young state of the project? Thanks!

[Libvir] Release of libvir-0.0.1
by Daniel Veillard 19 Dec '05

19 Dec '05

First release based on today's CVS snapshot is available for download from http://libvir.org/downloads.html I just added python bindings before the release, unfortunately I noticed only after that the destructor for the virDomain and virConnect classes were broken <grin/>. Well it is definitely a Work in Progress and sticking with CVS might be a good idea at the moment.

It is not using libxc for a couple of reasons: - to decouple the API from Xen, with the hope it will help provide API stability with an intermediate abstraction - due to the licence: if the LGPL library requires to link with a GPL library well the resulting programs can only be used under the GPL licence. It is smaller than libxc in term of capabilities, the goal is not to try to match those exactly, it can be expanded if there is demand though but it's more about providing generic services. For example there is an API do dump running domain informations as an XML chunk that could be used as well for different kind of virtualization engine, and is more high level than what libxc provides.
