[libvirt] nwfilter: limit VM traffic to specific MAC
by Shahar Havivi 20 Jun '11

20 Jun '11

Hi, I am trying to add custom filter to block VM traffic to other VMs by limiting the traffic only to the gateways MAC address. The filter XML: <filter name='rhev' chain='root'> <uuid>cd4e5890-ccc9-1b0f-303f-e7fe7123646d</uuid> <filterref filter='allow-dhcp'/> <rule action='drop' direction='out' priority='500'> <mac match='no' dstmacaddr='$MAC'/> </rule> </filter> The MAC is not the interface MAC address it's the gateways MAC that pass as a parameter (I use the gateway address hardcoded as well). The VM is getting DHCP ip but cannot get any traffic, I notice that when I edit (comment and uncomment) the drop rule, the filter is working fine, ie no traffic other then the gateway. 1. Am I doing something wrong? 1. What is the table name that libvirt use for ebtables? Shahar.

[libvirt] Availability of patchchecker
by Daniel Veillard 20 Jun '11

20 Jun '11

As some may have noticed, I'm often behind on patch review and it happens I notice patches way too late i.e. just before a release. For some time I though that having something automatic to remind me about unreviewed/unapplied patches would be a good way to fight this. I know that Eric, Matthias, Dan ... scans mostly everything but well are all getting quite busy and sometime things get forgotten and that's bad for the person who spent time on it and it's bad for the community. Asking to resend old patches tend to inflate the problem it's not a solution and humanly it's poor taste. So I spent most part of the week writing patchchecker, it's an automated tool, working out of the public mail archives and a git checkout, and was tested only with libvirt but should work also with other projects using MHonarc for mail archives and git (or could be made more flexible, yadda yadda ...) http://www.libvirt.org/git/?p=patchchecker.git git clone git://libvirt.org/patchchecker.git Check the README, there is an indexer to run regulary to extract from the mail archives, and a command to try to show intereting things, right now it reports only patches which didn't get any comments or acks. It detects patchset but doesn't fully use them yet. It's crude but it's automatic ! Next step is to so a bit of XML output and XSLT to export the output as a web page on libvirt.org , I will also need to add support for patch versioning i.e. being able to obsolete an older version with a newer mail (or patch set). I guess discussion and patches should be held and sent to this list, which already raises a limitation of this tool: it currently support only one git checkout, and if you send a patch for it it will complain if it doesn't get applied after being ACK'ed :-) BTW one of the results is that we should try to use the formal ACK keyword all the time (capital) when accepting and commiting a patch and I may occasionally send reply mail to threads with ACK or something like COMMITED if the algorithm of the checker get stuck on one patch. I really expect the amount of manual intervention to be limited to this I want the tool to help me, not give me/us more work :-) Hopefully it may prove useful to a few of us, and possibly be adapted to other projects (as usual I take patches :-) Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

Hi Henrik, what exactly did you to do to get the error page? I never run into those in any version I'm having in libvirt-php git repository since I always check but it may be Apache & PHP version connected and I'm running it as a module. Could you please provide me more information about this or at least provide me the results of `make check` command in the libvirt-php directory as cloned from git? Please note that to try to `make check` you need to install it first so you need to do `make`, then `(sudo) make install` and then `make check`. The `make check` command is running the tests and you shouldn't be seeing any segmentation fault there otherwise there's some bug in the code which obviously seems to be reproducible only on your environment since it's not reproducible on my environment at all. All the tests pass in my case: $ make check ... Making check in tests make[1]: Entering directory `tests' ./runtests.sh Test test-connect.phpt has been completed successfully Test test-version-check.phpt has been completed successfully Test test-version-get.phpt has been completed successfully Test test-domain-define-undefine.phpt has been completed successfully Test test-domain-define-create-destroy.phpt has been completed successfully Test test-domain-create.phpt has been completed successfully Test test-domain-create-and-get-xpath.phpt has been completed successfully Test test-domain-create-and-coredump.phpt has been completed successfully Test test-domain-snapshot.phpt has been completed successfully All tests passed successfully ... $ Could you please provide me with the Apache logs as well and also the Apache and PHP version numbers? You mention Drupal, did you integrate libvirt-php functionality into Drupal? The backtraces using xdebug should be sufficient. Please provide me with them.

[libvirt] [PATCH] Move XenAPI driver to correct spec file section
by Matthias Bolte 20 Jun '11

20 Jun '11

The XenAPI driver works like the ESX and PHyp driver by using its own HTTPS based remote protocol. --- libvirt.spec.in | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/libvirt.spec.in b/libvirt.spec.in index 97ebd65..75b145a 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -44,13 +44,13 @@ %define with_lxc 0%{!?_without_lxc:%{server_drivers}} %define with_vbox 0%{!?_without_vbox:%{server_drivers}} %define with_uml 0%{!?_without_uml:%{server_drivers}} -%define with_xenapi 0%{!?_without_xenapi:%{server_drivers}} %define with_libxl 0%{!?_without_libxl:%{server_drivers}} %define with_vmware 0%{!?_without_vmware:%{server_drivers}} # Then the hypervisor drivers that talk a native remote protocol %define with_phyp 0%{!?_without_phyp:1} %define with_esx 0%{!?_without_esx:1} +%define with_xenapi 0%{!?_without_xenapi:1} # Then the secondary host drivers %define with_network 0%{!?_without_network:%{server_drivers}} -- 1.7.0.4

[libvirt] [PATCH v4 RESEND 0/3] Add filesystem pool formatting
by Osier Yang 20 Jun '11

20 Jun '11

Hi, The following patches add the ability to format filesystem pools when the appropriate flags are passed to pool build. This patch set introduces two new flags: VIR_STORAGE_POOL_BUILD_NO_OVERWRITE causes the build to probe for an existing pool of the requested type. The build operation formats the filesystem if it does not find an existing filesystem of that type. VIR_STORAGE_POOL_BUILD_OVERWRITE causes the build to format unconditionally. [PATCH 1/3] storage: Add mkfs and libblkid to build system [PATCH 2/3] storage: Add fs pool formatting [PATCH 3/3] storage: Add virsh support for fs pool formating Regards Osier

[libvirt] [PATCH] build: fix building error when building without libvirtd
by Wen Congyang 20 Jun '11

20 Jun '11

When building libvirt without libvirtd, we will receive the following error message: make[3]: Entering directory `/home/wency/rpmbuild/BUILD/libvirt-0.9.2/tools' CC virsh-virsh.o CC virsh-console.o GEN virt-xml-validate GEN virt-pki-validate CCLD virsh ../src/.libs/libvirt.so: undefined reference to `numa_available' ../src/.libs/libvirt.so: undefined reference to `numa_max_node' collect2: ld returned 1 exit status The reason is that: we check numactl only when building qemu driver, and qemu driver will not be built when bulding without libvirtd. So with_numactl's value is check and we will not link libnuma.so. In the other function, we call numa_available() and numa_max_node() only when HAVE_NUMACTL is 1. We should do the same check in the function nodeGetMemoryStats(). --- src/nodeinfo.c | 6 ++++++ 1 files changed, 6 insertions(+), 0 deletions(-) diff --git a/src/nodeinfo.c b/src/nodeinfo.c index 647cb1e..c6dbb84 100644 --- a/src/nodeinfo.c +++ b/src/nodeinfo.c @@ -685,17 +685,23 @@ int nodeGetMemoryStats(virConnectPtr conn ATTRIBUTE_UNUSED, return -1; } } else { +#if HAVE_NUMACTL if (numa_available() < 0) { +#endif nodeReportError(VIR_ERR_NO_SUPPORT, "%s", _("NUMA not supported on this host")); return -1; +#if HAVE_NUMACTL } +#endif +#if HAVE_NUMACTL if (cellNum > numa_max_node()) { nodeReportError(VIR_ERR_INVALID_ARG, "%s", _("Invalid cell number")); return -1; } +#endif if (virAsprintf(&meminfo_path, "%s/node%d/meminfo", NODE_SYS_PATH, cellNum) < 0) { -- 1.7.1
