Hello Matthias, I trying rebuiling the 32 bit dlls by following instructions at https://github.com/photron/msys_setup/blob/master/readme_libvirt.txt and I get a new error (note: I did not redo instructions at https://github.com/photron/msys_setup/blob/master/readme.txt)

I will try to re-build the 32 bit dlls using your msys_setup script.
Also thank you for explanation for my other questions.

My understanding is that libvirt.jar uses JNA to call libvirt's native windows library. I tried using the libvirt dlls in the experimental Windows installation package mentioned in http://libvirt.org/windows.html at http://libvirt.org/sources/win32_experimental/Libvirt-0.8.8-0.exe the below Java exception :
Exception in thread "main" java.lang.UnsatisfiedLinkError: %1 is not a valid Win32 application.

But when I try the same client code on a Windows XP 32 bit machine (with 32 bit JVM), I don't see this problem and the connection succeeds. So it looks like the problem is that I am not using 64 bit windows libvirt dlls. Is my assumption correct? Is there a Windows installer with 64 bit Libvirt dlls ? Or are the 64 bit version of DLLs
somewhere?
A 64bit process cannot use 32bit DLLs. You'll need
and its dependencies compiled for 64bit. I'm not aware of any pre-compiled 64bit libvirt DLLs.
I tried using Matthias Bolte's msys_setup script (I tried in 2 machines) and in both machines, I get the below error when I try to run compile_libxml2.sh as per instructions https://github.com/photron/msys_setup/blob/master/readme_libvirt.txt
Last few lines before the error is :

I just fixed this problem, but this won't help you with your 64bit problem. My msys_setup scripts compile libvirt for 32bit and it isn't that easy to extend them for 64bit. This is mainly due to libvirt's dependencies. For example, for gnutls the scripts just download pre-compiled 32bit DLLs. It'll require some work to get libvirt and its dependencies compiled for 64bit.
