Note: I am not using brcompat, I believe it's obsolete in the OVS version I'm running). Thanks, Chris.

[libvirt-users] Way for a VM to reboot from a snapshot?
by Ken Coar 11 May '13

11 May '13

Using the koan command, a VM can essentially request that it be reprovisioned. Is there any way for a VM to request that it reboot from a snapshot taken with virsh? Thanks.. -- #ken B-)} Ken Coar, RHCE, RHCSA, Sanagendamgagwedweinini IT Engineering Tower, Red Hat/RDU "Millennium hand and shrimp!"

[libvirt-users] latency between LIFECYCLE event and notification generation
by nishant burte 10 May '13

10 May '13

Hi, I have registered for LIFECYCLE events of libvirt. But I don't know, 1. about the the latency of these events happening and notification generation. e.g. suppose a VM goes down. How much time it takes to realize that the particular VM has gone down(going to say, DEFINED state) and then notification is generated? 2. Second question is, can someone please explain what are the sequence of steps happen between a VM going down and the notification is generated? Coul you please answer both the queries? Thanks Nishant

[libvirt-users] libvirt daemon and numad daemon
by Gao Yongwei 09 May '13

09 May '13

Hello all, I installed libvirt-0.10.2-18.el6.x86_64 ,is there any relationship between libvirtd and numad ? I found that when I started numad daemon , the vm can start in a shorter time, but when numad daemon stoped , vm could still start ,just with a longer start time. how does this work with the two daemons? thanks.

[libvirt-users] unable to do kerberos authentication

Hello, I am trying to do kerberos (sasl+gssapi) authentication for a hypervisor running libvirt. When I have valid kerberos credentials these errors end up in my logs.

[libvirt-users] migration job: unexpectedly failed
by Daniele 09 May '13

09 May '13

Hi, I am trying to run some test and analysis while performing a wide live migration of a VM between two different network location. I use libvirt and qemu-kvm as hypervisor on Linux. The live wide migration from A to B completes successfully, instead I can't achieve the reverse path, from B to A (and that is right what I am interested to). To perform the migration I run this command in virsh: *"migrate --live --verbose uno qemu+ssh://root@ip.address/system"* * * Even if dramatically slow (i guess due to some network bottleneck) the migration starts correctly, but it gets stuck at 96% and after some minute it returns this error: *"Migration: [ 96 %]error: operation failed: migration job: unexpectedly failed" *without further details. The libvirtd.log file in the source host says: *2013-05-07 11:01:18.739+0000: 9538: error : qemuMigrationUpdateJobStatus:945 : operation failed: migration job: unexpectedly failed* * * Apparently i can't find any clue of what is causing the error, do you have any idea/solution? * * (I'm not sure if this is the appropriate mailing-list, maybe it was better the devs list?) Thanks for your help Daniele

[libvirt-users] Java client error on Windows 7 64 bit for Libvirt on KVM
by george john 08 May '13

08 May '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. Is my assumption correct? 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?

Hi, Are there packages of "libvirt-snmp" for Ubuntu? Or instructions to compile libvirt-snmp on Ubuntu? Looks like the instructions given at http://wiki.libvirt.org/page/Libvirt-snmp are for RedHat. Thank you, George

[libvirt-users] libvirt API reference disappeared from website
by Ulrich Hochholdinger 07 May '13

07 May '13

Hi, I think the API Reference for libvirt disappeared from libvirt.org: browsing to http://libvirt.org/html/libvirt-libvirt.html delivers no content. The content is still available via google cache http://webcache.googleusercontent.com/search?q=cache:libvirt.org/html/libvi… So, is this removed on purpose? Or is this some bluff from my browser (but I checked this from different sites with different browsers ;-/ )? Cheers, Ulli -- Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us. (calvin)
