Hi, I found an answer : Use virConnectOpenAuth() instead of virConnectOpenReadOnly(). As my piece of code is running silently (without user connected) , by using virConnectOpenAuth() , is it possible to avoid to prompt user to get user /password ? Thx.

As ovirt manager shows the address correctly , it should be possible to get it via libvirt ... Thanks for help. J.P. Ribeauville P: +33.(0).1.47.17.20.49 .
