Hi all, I'm Alejandro Berna from i2CAT (a non-profit foundation in Barcelona, Spain, www.i2cat.net). I'm collaborating in a Europena project called Federica ( www.fp7-*federica*.eu ). One of the branch of this project is to permit virtualization of different hosts in the Federica test-bed. We are doing some studies about the different management interfaces of Xen. Our objective is to create a software remote client for Xen tool (in java if it's possible) that can do (general functionalities): - Create virtual machines assigning virtual interfaces. - Permit choose the OS assigned to this virtual machine - Install new applications to be tested in the virtual machines - Configure a vm to become a router and permit to configure this router as it was a physical router. All these actions have to be performed remotelly. I have not found too much information about libvrt but I think that can be usefull for our achieves. If you agree that with libvrt we can perform these actions, maybe I can build the java bindings for libvrt inside the Federica work. I'm waiting for your opinions, thank you,

That versions should be ready for consumption, and I will push it for example for Fedora-9 . Give me just 2 more hours, it should show up at ftp://libvirt.org/libvirt/java/ Daniel -- Red Hat Virtualization group http://redhat.com/virtualization/ Daniel Veillard | virtualization library http://libvirt.org/ veillard(a)redhat.com | libxml GNOME XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | Rpmfind RPM search engine http://rpmfind.net/

Well it should be basically working, except for parts which are not yet covered (some of the new APIs added after 0.4.0), and bugs in the code which is relatively new. We are also lacking documentation except for the javadoc ones, that's something i will try to fix in the following days, General feedback, bug reports and patches all welcome :-) Daniel -- Red Hat Virtualization group http://redhat.com/virtualization/ Daniel Veillard | virtualization library http://libvirt.org/ veillard(a)redhat.com | libxml GNOME XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | Rpmfind RPM search engine http://rpmfind.net/

I finally added some informations on-line at http://libvirt.org/java.html I don't know why the javadoc output seems to be missing frames or something (using a java-1.5.0-ibm javadoc ...), but at least the basic is there http://libvirt.org/org/libvirt/package-summary.html Daniel -- Red Hat Virtualization group http://redhat.com/virtualization/ Daniel Veillard | virtualization library http://libvirt.org/ veillard(a)redhat.com | libxml GNOME XML XSLT toolkit http://xmlsoft.org/ http://veillard.com/ | Rpmfind RPM search engine http://rpmfind.net/

Hi Daniel, all, I'm sorry for my non show during the summer but I was in my long holidays ;)....

I will have the libvirt project for Eclipse with the libvirt java bindings during this month, if I use as a base the makefile it wouldn't be too complicate to generate.

Also I would like to ask you (because we need for our Federica project) if libvirt is using CIM model or is using something similar. I read that is collaborating with DMTF but we have not found anything that tells that libvirt is using CIM model. If you don't know exactly can you tell me who to contact to assure this? I hope you can help me, thank you for everything,
