[libvirt] routed networking
by Ben Guthro 09 Jul '08

09 Jul '08

Hello Perhaps this is my limited understanding of bridging, and I would appreciate someone to educate me in the way this is supposed to work, and/or point me to the documentation on where this is covered. If I create a routed network using the following xml: <network> <name>mybr0</name> <bridge name="mybr0" /> <ip address="10.1.220.1" netmask="255.255.255.0" /> <forward type="route" dev="eth1"/> </network> I would expect to see the eth1 interface enslaved to this bridge. However, "brctl show" does not show any devices enslaved. My goal is to have the guest get its IP address from a DHCP server not on dom0, but out on the network attached to by eth1, but as my guest comes up, I see its virtual NIC added to the bridge, but without the connection to eth1, it never has the proper connectivity. Any help understanding this would be appreciated. Ben

[libvirt] PATCH: Fix booting QEMU off CDROM
by Daniel P. Berrange 08 Jul '08

08 Jul '08

KVM supports an alternate syntax for indicating a boot device when the -drive parameter is available. Instead of -boot c, it allow 'boot=on' to be set for the -drive parameter. Unfortauntely it turns that this doesn't work with certain CDROM images, in particular Fedora 9 https://bugzilla.redhat.com/show_bug.cgi?id=452355 Discussion with upstream indicates we're lucky it ever worked at all for CDROM media. So this patch removes use of the boot=on flag for CDROM devices. NB, even when we added boot=on, we always still added -boot d param too, so merely removing the boot=on flag is sufficient to make it work again. src/qemu_conf.c | 3 - tests/qemuxml2argvdata/qemuxml2argv-disk-drive-boot-cdrom.args | 1 tests/qemuxml2argvdata/qemuxml2argv-disk-drive-boot-cdrom.xml | 26 ++++++++++ tests/qemuxml2argvdata/qemuxml2argv-disk-drive-boot-disk.args | 1 tests/qemuxml2argvdata/qemuxml2argv-disk-drive-boot-disk.xml | 26 ++++++++++ tests/qemuxml2argvtest.c | 4 + 6 files changed, 60 insertions(+), 1 deletion(-) Daniel diff -rupN libvirt-0.4.4.orig/src/qemu_conf.c libvirt-0.4.4.new/src/qemu_conf.c --- libvirt-0.4.4.orig/src/qemu_conf.c 2008-06-19 14:15:02.000000000 +0100 +++ libvirt-0.4.4.new/src/qemu_conf.c 2008-07-08 12:24:07.000000000 +0100 @@ -2616,7 +2616,8 @@ int qemudBuildCommandLine(virConnectPtr disk->src, qemudBusIdToName(disk->bus, 1), media ? media : "", idx, - bootable ?

[libvirt] MinGW Windows cross-compiler in Fedora, compiling libvirt
by Richard W.M. Jones 08 Jul '08

08 Jul '08

We've set up a SIG (Special Interest Group) for people interested in adding a Windows cross-compiler to Fedora: https://fedoraproject.org/wiki/SIGs/MinGW The primary target at the moment is to allow libvirt to be cross- compiled on a Fedora machine, targetting Windows. This will allow us to do more regular testing on the Windows build and ensure it doesn't break so often. At the moment you can already build all dependencies of libvirt, and libvirt itself, but only statically (see detailed reasons below). I also got virsh.exe working, and there seems to be no reason why other C programs linked to libvirt wouldn't work too. For the dependencies, start with the README file here: http://hg.et.redhat.com/misc/fedora-mingw--devel Building libvirt ---------------- After building and installing the dependencies, you will be able to build libvirt from CVS (*not* libvirt 0.4.4 since that had a MinGW bug which was subsequently patched): CC="i686-pc-mingw32-gcc -I/usr/i686-pc-mingw32/sys-root/mingw/include/libxml2" \ ./configure \ --host=i686-pc-mingw32 \ --prefix=/usr/i686-pc-mingw32/sys-root/mingw \ --without-xen \ --without-qemu \ --without-libvirtd \ --without-sasl \ --disable-shared make Running programs under Wine --------------------------- If Wine is installed, you can just run programs like virsh.exe directly. Make sure any required DLLs are on your path. It's possible we could get the test suite running using Wine, but I haven't tried this. Current problems for libvirt on Windows/MinGW --------------------------------------------- No python. Either it was my imagination, or we've lost the '--disable-python' configure option. In any case we should be able to detect that Python isn't going to work or disable it completely, so the build doesn't fail at this point. Libxml2 detection is broken (again?). The configure script insists on finding the system library, not the MinGW sys-root library. Hence the strange $CC variable above. Static linking only: The problem here is that PortableXDR uses a Windows library called Winsock (ws2_32.dll). MinGW doesn't provide a dynamic version of this library, only a static version -- I'm not sure why this is, obviously though if you were running on Windows then you'd have the MSFT binary DLL. Hence PortableXDR can only be linked statically. This implies that libvirt can also only be linked statically. I think this is easy to solve: PortableXDR only uses a handful of simple functions from Winsock, which we can just get from Gnulib or some other source instead. ----------- Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-top is 'top' for virtual machines.

[libvirt] trying to 'destroy' a domain with Python bindings...
by Michael March 08 Jul '08

08 Jul '08

When I do this: conn.lookupByName('myDomU').destroy() ... I get this: Traceback (most recent call last): File "test.py", line 30, in ? print conn.lookupByName('myDomU').destroy() File "/usr/lib64/python2.4/site-packages/libvirt.py", line 238, in destroy if ret == -1: raise libvirtError ('virDomainDestroy() failed', dom=self) libvirt.libvirtError: virDomainDestroy() failed What am I missing here? Destroy should do the equivalent of 'Delete' on virt-manager, correct? thanks! (BTW... I'm running stock RH5.2.)

[libvirt] [PATCH] update libvirt.rng
by John Levon 07 Jul '08

07 Jul '08

The below patch makes a significant update to libvirt.rng to bring it into line with reality. This is an incremental improvement rather than a full fix. In particular, various parts are still under-specified (e.g. qemu char devices). This version lets almost all of the XML files in tests/ validate. I'd appreciate help getting the last few to validate - any volunteers? One possible idea might be virsh validate: split out both the schema validation and the additional checks in libvirt into one consolidated place. This would help people check their definitions. The question also arises on how to help avoid the schema getting so badly out of date again. Some suggestions: - add a validation phase to the test suite, and mark failures - require any changes to the implicit schema to add a test suite entry - and require such changes to update the schema too Comments? thanks, john Index: docs/libvirt.rng =================================================================== RCS file: /data/cvs/libvirt/docs/libvirt.rng,v retrieving revision 1.7 diff -u -r1.7 libvirt.rng --- docs/libvirt.rng 14 Mar 2008 11:08:03 -0000 1.7 +++ docs/libvirt.rng 4 Jul 2008 22:22:52 -0000 @@ -50,6 +50,7 @@ </optional> </group> </choice> + <ref name='clock'/> <ref name='resources'/> <ref name='features'/> <ref name='termination'/> @@ -82,8 +83,13 @@ </choice> <value>hvm</value> </element> + <optional> + <ref name='bootdev'/> + </optional> </element> + <ref name='clock'/> <ref name='resources'/> + <ref name='termination'/> <ref name='devices'/> </interleave> </group> @@ -157,8 +163,14 @@ <interleave> <element name='os'> <element name='type'> -

[libvirt] Re: Libvir-list Digest, Vol 32, Issue 7
by Tóth István 07 Jul '08

07 Jul '08

I took at a look at that code. The JNI code is basically unchanged from the 0.1 version. The interesting part is the code is for handling the XML structures used by libvirt. You can see how Daniel Schweger's added functionality is meant to be used in the srtc/testclient/org/libvirt/TestXen.java file. The way I imagined the java-libvirt architecture is that there is a lower 'core' level, which is basically a function-for function equivalent of the C libvirt functionality, with the bare minimum of object-orientedness thrown in to pass for a proper java library (the current libvirt in CVS) Plus, there should/can be anotherl API, that exposes the XML files as java objects with get/set functions, etc. (It's in the org.libvirt.schema package in Daniel Schweger's code) Optionally, there could be higher level API that uses the core and XML api, and provides a really clean java-style object model, but IO haven't given it much thought yet. I think these two or three layers should be clearly demarcated, maybe even shipped as separate packages, becuse anything that layers on more functionaity that what the current cvs provides represents design decisions that are not inherent to libvirt. One may not want to use the XML technology/object model/whatever that libvirt-java ships, but rather add their own XML handling stuff/ higher level abstractions on top of the core libvirt bindings. (for example, Daniel Schweger's code uses XMLBeans, my original idea was to use JAXB for the same purpose). BTW I am working on adding the core bindings for the storage stuff, but don't expect anything soon, as my day job is currently eating all my time. regards István libvir-list-request(a)redhat.com wrote: > Send Libvir-list mailing list submissions to > libvir-list(a)redhat.com > > To subscribe or unsubscribe via the World Wide Web, visit > https://www.redhat.com/mailman/listinfo/libvir-list > or, via email, send a message with subject or body 'help' to > libvir-list-request(a)redhat.com > > You can reach the person managing the list at > libvir-list-owner(a)redhat.com > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Libvir-list digest..." > > > Today's Topics: > > 1.

[libvirt] Xen config files again
by Thomas Moyer 07 Jul '08

07 Jul '08

I've seen in the src tree that there are functions to read and use Xen configuration files. Are these functions available in the Python bindings or do I need to use C to get access to them? What I am mostly interested in doing is parsing the Xen config file and getting back the XML version that I can store and use later on. -- Thomas Moyer Graduate Student CSE Department Penn State University tmmoyer(a)cse.psu.edu http://www.cse.psu.edu/~tmmoyer

[libvirt] 'starting' a domain using Python libvirt..
by Michael March 07 Jul '08

07 Jul '08

I'm trying to figure out how to start a domain .. and I can't figure out what method to use.. When I do this: >>> dir(conn.lookupByName('my-vm-1')) I get these options: ['ID', 'OSType', 'UUID', 'UUIDString', 'XMLDesc', '__del__', '__doc__', '__init__', '__module__', '_conn', '_o', 'attachDevice', 'autostart', 'blockStats', 'connect', 'coreDump', 'create', 'destroy', 'detachDevice', 'info', 'interfaceStats', 'maxMemory', 'maxVcpus', 'migrate', 'name', 'pinVcpu', 'reboot', 'resume', 'save', 'setAutostart', 'setMaxMemory', 'setMemory', 'setVcpus', 'shutdown', 'suspend', 'undefine'] I don't see a method to start a domain up.. What am I missing here? thanks!
