[libvirt] [PATCH libvirt-python v3 00/40] Split python binding into separate repo
by Daniel P. Berrange 25 Nov '13

25 Nov '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> This patch series is a followup to https://www.redhat.com/archives/libvir-list/2013-November/msg00712.html This series is what I consider ready to declare final, ready for the real GIT repo split to be done. Starting from libvirt GIT master as of commit bae383f29194b9c61f9ab245f493ce7d654868d1 Author: Daniel P. Berrange <berrange(a)redhat.com> Date: Fri Nov 22 14:32:23 2013 +0000 I did the following $ git clone libvirt libvirt-python $ cd libvirt-python $ git mv examples/python python/examples $ git mv examples/domain-events/events-python/event-test.py python/examples $ git commit $ git filter-branch --subdirectory-filter python --tag-name-filter cat -- --all $ git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d $ git reflog expire --expire=now --all $ git gc --prune=now Then applied the following 40 patches using git am -3 You should now have a repo that's a couple of MB in size, showing only the files from python/ dir, in the root. The tags have been re-written to show content from the python/ directory. All the GPG signatures from tags are removed, since they are invalid after rewriting history. This was previously agreed to be the right way to handle this. The build system uses python distutils instead of autoconf/automake. It still uses the code generator as before though, pulling the XML files from /usr/share/libvirt/api (or whever you installed libvirt, as indicated by pkg-config). created a simple autobuild.sh to do an end-to-end build, including the RPM generation. Or you can just do python setup.py build ('make' equiv) python setup.py test ('make check' equiv) python setup.py rpm ('make rpm' equiv) python setup.py clean ('make clean' equiv) Historically libvirt python only worked with the exact matching libvirt binary. With this series, it is now possible to compile against any version back to 0.9.11. It is not possible to go back further than this, since the libvirt-api.xml file we need was not installed into /usr/share prior to 0.9.11. As such I removed Doug's patches which dealt with 0.9.6->0.9.10 Fortunately it seems 0.9.11 is in fact sufficient for OpenStack's targetted distros. The full GIT tree is git clone git://fedorapeople.org/~berrange/libvirt-python-v9.git Please take a moment to examine this. Unless bugs are found, this GIT repo will be moved as-is onto libvirt.org GIT. For doing releases, the following process would be needed ...build and install the new libvirt release RPM first... $ cd libvirt-python.git $ git tag -s -m 'Release 1.2.0' v1.2.0 $ ./autobuild.sh $ git push master v1.2.0 Now the 'dist/libvirt-python-X.y.z.tar.gz' file should be copied to http://libvirt.org/sources/python/ and also uploaded to PyPI Distutils can do the upload, but is deprecated since it passes your passwd in cleartext over the net :-( Instead OpenStack guys recommend use of twine https://pypi.python.org/pypi/twine eg $ twine upload dist/libvirt-python-x.y.z.tar.gz Unfortunately 'twine' isn't in Fedora repos, but is easy to install it locally using 'pip install twine' Daniel Daniel P.

[libvirt] Libvirt, nwfilter, openvswitch
by Jan De Landtsheer 23 Nov '13

23 Nov '13

Hello, I _was_ trying to set up an nwfilter for our networking set-up with VXLAN and openvswitch, where we use VXLAN as carrier for separate networks (unlike OpenStack gre-tunnels). But with OVS, ebtables do not work, and the basic setup of nwfilter rules are based on this premise... or so I understand... Now.. Is there a way to define nwfilter rules _without_ ebtables ? What I would like to do is quite simple (block out dhcp{4,6} services from VM's, and ipv6 router advertisements ) Thanks

OK. Let's see where the qemu patch goes (I'll have to fix the comment typo that Eric found), and if it is accepted (maybe with modifications), we can return to the OVMF patch. > Many of these scenarios were discussed in the past on qemu-devel, but > a single -pflash was the only thing that stuck. But (thanks to you) we now have a flash driver in OVMF that works *in practice*. The discussion about multiple -pflash flags is not academic any longer. (Hm, sorry, that's maybe too strong -- I can't really say if the discussion used to be academic before. But it cannot have been this practical.) We also know that the libvirt developers prefer the split file. Plus: > This has made me just > focus on making the single file pflash work. You also can't deny that > the QEMU command line gets ugly real fast. We're in violent agreement on that -- which emphasizes the need for good libvirt support all the more. Seriously, I refuse to work with the qemu command line day to day. I have an elaborate wrapper script that I insert between qemu and libvirt (specified in the <emulator> libvirt domain XML) that post-processes the arguments composed by libvirt. I need this to test out features that libvirt doesn't yet support. For example, I can set various filenames in the <loader> element -- it specifies the argument to the -bios option. In the script I check the argument against various patterns, and I can turn it into: - -bios "$ARG" - -pflash "$ARG" - -pflash "$ARG" -pflash "$(manipulate "$ARG")" The script handles CSM vs. pure-UEFI for Windows 2008, it can honor upstream vs. RHEL qemu differences, it can turn off the iPXE virtio-net driver. In the single -pflash option case, it does refresh the code part in the VM's copy of OVMF (with dd) from my most recent build. It sets a name-dependent output file for the debug port. Etc. Maintaining this script over months has paid off orders of magnitude better than working with the raw qemu command line would have. (I can compare: on my (occasionally used) AMD desktop that runs Debian I have not bothered to install libvirt, and each time I need to modify the forty line qemu command that I keep in a script file, I cringe. And I can't bring myself to install a second guest.) The convenience/efficiency libvirt gives me is critical. Changing boot order, adding or removing devices, starting & stopping -- these are very fast in virt-manager. Editing the configuration with virsh is nice (and it has some level of automatic verification when you save and exit). Comparing guest configs against each other (using the XMLs) is very convenient. And so on. I depend on these every day, but I need to modify the wrapper script only occasionally. Libvirt still allows me to send custom monitor commands, and I can set it to log all of its *own* commands that it sends to the monitor or the guest agent. I've always wondered how other developers (for example, you :)) can exist without libvirt at all! That is why "keep the qemu command line simple" (== approx. "two -pflash options are inconvenient") is no concern of mine. That ship has sailed. Thanks, Laszlo

[libvirt] [PATCH] storage: allow interleave in volume XML

[libvirt] [PATCH] virsh domxml-from-native to treat SCSI as the bus type for pseries by default
by Shivaprasad G Bhat 22 Nov '13

22 Nov '13

From: Shivaprasad G Bhat <shivaprasadbhat(a)gmail.com> The bus type IDE being enum Zero, the bus type on pseries system appears as IDE for all the -hda/-cdrom and for disk drives with if="none" type. Pseries platform needs this to appear as SCSI instead of IDE. The ide being not supported, the explicit requests for ide devices will return an error.

[libvirt] Planning for next release
by Daniel Veillard 22 Nov '13

22 Nov '13

If we want to land a release on Mon Dec 2, I would suggest entering freeze next week. The amount of patches since 1.1.4 is not very large so we could start the freeze say on Wed 27, but IMHO it all depennds if Dan patches about splitting out the python bindings gets in for that release. If yes I would probably prefer to freeze one more day (start Tues 26), and bump release name to 1.2.0 as this is a significant change from an user perspective, otherwise 1.1.5 and freeze next Wed. Opinions ? Dan do you think you can/want to land this set in the coming week ?

[libvirt] [PATCH] Mostly revert "python: remove virConnectGetCPUModelNames from globals"
by Daniel P. Berrange 22 Nov '13

22 Nov '13

From: "Daniel P. Berrange" <berrange(a)redhat.com> This reverts commit 6b90d7428d72e92db292a9228c44701bfd5003c9. The original problem was that libvirt_virConnectGetCPUModelNames was listed twice in the exports table, once automatically from the generator and once from the manual override. We merely needed to list it in the skip_impl list, and not delete the manually written code entirely. --- python/libvirt-override.c | 53 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 53 insertions(+) diff --git a/python/libvirt-override.c b/python/libvirt-override.c index 2f520c1..6546dd1 100644 --- a/python/libvirt-override.c +++ b/python/libvirt-override.c @@ -2276,6 +2276,58 @@ libvirt_virConnectGetVersion(PyObject *self ATTRIBUTE_UNUSED, return PyInt_FromLong(hvVersion); } +PyObject * +libvirt_virConnectGetCPUModelNames(PyObject *self ATTRIBUTE_UNUSED, + PyObject *args) +{ + int c_retval; + virConnectPtr conn; + PyObject *rv = NULL, *pyobj_conn; + char **models = NULL; + size_t i; + int flags = 0; + const char *arch = NULL; + + if (!PyArg_ParseTuple(args, (char *)"Osi:virConnectGetCPUModelNames", + &pyobj_conn, &arch, &flags)) + return NULL; + conn = (virConnectPtr) PyvirConnect_Get(pyobj_conn); + + LIBVIRT_BEGIN_ALLOW_THREADS; + + c_retval = virConnectGetCPUModelNames(conn, arch, &models, flags); + + LIBVIRT_END_ALLOW_THREADS; + + if (c_retval == -1) + return VIR_PY_INT_FAIL; + + if ((rv = PyList_New(c_retval)) == NULL) + goto error; + + for (i = 0; i < c_retval; i++) { + PyObject *str; + if ((str = PyString_FromString(models[i])) == NULL) + goto error; + + PyList_SET_ITEM(rv, i, str); + } + +done: + if (models) { + for (i = 0; i < c_retval; i++) + VIR_FREE(models[i]); + VIR_FREE(models); + } + + return rv; + +error: + Py_XDECREF(rv); + rv = VIR_PY_INT_FAIL; + goto done; +} + static PyObject * libvirt_virConnectGetLibVersion(PyObject *self ATTRIBUTE_UNUSED, PyObject *args) @@ -7176,6 +7228,7 @@ static PyMethodDef libvirtMethods[] = { #include "libvirt-export.c" {(char *) "virGetVersion", libvirt_virGetVersion, METH_VARARGS, NULL}, {(char *) "virConnectGetVersion", libvirt_virConnectGetVersion, METH_VARARGS, NULL}, + {(char *) "virConnectGetCPUModelNames", libvirt_virConnectGetCPUModelNames, METH_VARARGS, NULL}, {(char *) "virConnectGetLibVersion", libvirt_virConnectGetLibVersion, METH_VARARGS, NULL}, {(char *) "virConnectOpenAuth", libvirt_virConnectOpenAuth, METH_VARARGS, NULL}, {(char *) "virConnectListDomainsID", libvirt_virConnectListDomainsID, METH_VARARGS, NULL}, -- 1.8.3.1
