Hi, I need some help in building a Java client on Windows 7 64 bit plaftorm to manage a KVM using the libvirt APIs. Using the instructions at http://libvirt.org/java.html, i was able to build libvirt.jar. 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 but whenever I try to connect to my remote API, I get the below Java exception : Exception in thread "main" java.lang.UnsatisfiedLinkError: %1 is not a valid Win32 application. at com.sun.jna.Native.open(Native Method) at com.sun.jna.Native.open(Native.java:1718) at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:210) at com.sun.jna.NativeLibrary.getInstance(NativeLibrary.java:322) at com.sun.jna.Library$Handler.<init>(Library.java:142) at com.sun.jna.Native.loadLibrary(Native.java:387) at com.sun.jna.Native.loadLibrary(Native.java:366) at org.libvirt.jna.Libvirt.<clinit>(Unknown Source) at org.libvirt.Library.<clinit>(Unknown Source) at org.libvirt.Connect.<init>(Unknown Source) at Main.main(Main.java:8) 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 and 64 bit JVM cannot load 32 bit dlls. Is there a Windows installer with 64 bit Libvirt dlls ? Or are the 64 bit version of DLLs published somewhere? 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 : >>>>>>>>>>>>>>>>> make[5]: Leaving directory `/src/libxml2/libxml2-2.9.0-0/python' make[4]: Leaving directory `/src/libxml2/libxml2-2.9.0-0/python' Making install in tests make[4]: Entering directory `/src/libxml2/libxml2-2.9.0-0/python/tests' make[5]: Entering directory `/src/libxml2/libxml2-2.9.0-0/python/tests' make[5]: Nothing to be done for `install-exec-am'. test -z "/share/doc/libxml2-python-2.9.0/examples" || /bin/mkdir -p "/share/doc/ libxml2-python-2.9.0/examples" /bin/install -c -m 644 build.py attribs.py tst.py tstxpath.py xpathext.py push. py pushSAX.py pushSAXhtml.py error.py serialize.py validate.py tstURI.py cutnpas te.py xpathret.py xpath.py outbuf.py inbuf.py resolver.py regexp.py reader.py re ader2.py reader3.py reader4.py reader5.py reader6.py reader7.py reader8.py reade rnext.py walker.py nsdel.py ctxterror.py readererr.py relaxng.py schema.py threa d2.py sync.py tstLastError.py indexes.py dtdvalid.py tstmem.py '/share/doc/libxm l2-python-2.9.0/examples' /bin/install -c -m 644 validDTD.py validSchemas.py validRNG.py compareNodes.py xpathns.py xpathleak.py tst.xml valid.xml invalid.xml test.dtd '/share/doc/libxm l2-python-2.9.0/examples' make[5]: Leaving directory `/src/libxml2/libxml2-2.9.0-0/python/tests' make[4]: Leaving directory `/src/libxml2/libxml2-2.9.0-0/python/tests' make[3]: Leaving directory `/src/libxml2/libxml2-2.9.0-0/python' make[2]: Leaving directory `/src/libxml2/libxml2-2.9.0-0/python' make[1]: Leaving directory `/src/libxml2/libxml2-2.9.0-0' + cp /python/Lib/site-packages/libxml2mod.dll /python/DLLs/libxml2mod.pyd cp: cannot stat `/python/Lib/site-packages/libxml2mod.dll': No such file or dire ctory >>>>>>>>>>>>>>>>>> Do you know how this error could be resolved?
