[libvirt] libxl: expose and control xen device model versions
by David Scott 30 Apr '13

30 Apr '13

Hi, These patches expose multiple xen device model options in the capabilities XML and allow the user to select a specific device model via the domain XML's <emulator> tag. It is important to control the device model per VM, since the default is changing from xen-4.2 "qemu traditional" to xen-4.3 "qemu upstream". In this proposal, the capabilities XML now has multiple <domain> elements per <arch> as follows: <arch name='i686'> <wordsize>32</wordsize> <machine>xenfv</machine> <domain type='xen'> <emulator>/usr/lib64/xen/bin/qemu-dm</emulator> <loader>/usr/lib/xen/boot/hvmloader</loader> </domain> <domain type='xen'> <emulator>/usr/lib64/xen/bin/qemu-system-i386</emulator> <loader>/usr/lib/xen/boot/hvmloader</loader> </domain> </arch> -- is it valid/ sensible to have multiple <domain>'s with the same 'type'? Let me know if you can think of a better mapping. Comments, criticism welcome. Cheers, Dave

[libvirt] Java client error on Windows 7 64 bit for Libvirt on KVM
by george john 30 Apr '13

30 Apr '13

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?

[libvirt] [PATCH v2] qemu: Generate agent socket path if missing

[libvirt] RFE: Ability to freeze/thaw guest using libvirt/virsh APIs
by Deepak C Shetty 30 Apr '13

30 Apr '13

I am sending this mail based on the below IRC discussion. Apr 23 18:55:02 <deepakcs> Hi all, is there a way to just do a fsfreeze (and un-freeze) of VM usign virsh. I don't see any option today.... Apr 23 18:55:52 <deepakcs> there is option to take snapshot (which in turn would do freeze/un-freeze), but i want to exercise the freeze/un-freeze only.. w/o the snapshot Apr 23 19:23:57 <eblake> deepakcs: virsh qemu-agent-command can trigger any agent command Apr 23 19:24:35 <eblake> but it is officially unsupported - more of a development aid Apr 23 19:26:38 <eblake> if it turns out that freezing the guest with libvirt commands is worth promoting into a supported api, instead of the qemu-agent-command backdoor, then report that as an RFE to the list Apr 23 19:27:14 <deepakcs> eblake, sorry was in a mtg.. Apr 23 19:28:03 <deepakcs> eblake, yeah.. i was wondering that it would be good to have freeze/un-freeze as supported virsh ops.. then it helps users exploit snapshot functionality provided by things like storage arrays (as an example) Apr 23 19:28:47 <eblake> well, as qemu continues to add more snapshot building blocks, it may make sense
