[libvirt] [PATCH] xen config: No vfb in HVM guest configuration
by Stefan Bader 06 Apr '12

06 Apr '12

This causes an implicit vkbd device to be added which takes 6min to finally fail being initialized in the guest. http://lists.xen.org/archives/html/xen-devel/2012-04/msg00409.html Signed-off-by: Stefan Bader <stefan.bader(a)canonical.com> --- src/xenxs/xen_sxpr.c | 11 ++++------- src/xenxs/xen_xm.c | 2 +- 2 files changed, 5 insertions(+), 8 deletions(-) diff --git a/src/xenxs/xen_sxpr.c b/src/xenxs/xen_sxpr.c index b26b2bc..b2f98f6 100644 --- a/src/xenxs/xen_sxpr.c +++ b/src/xenxs/xen_sxpr.c @@ -2464,9 +2464,8 @@ xenFormatSxpr(virConnectPtr conn, } } - /* PV graphics for xen <= 3.0.4, or HVM graphics for xen <= 3.1.0 */ - if ((!hvm && xendConfigVersion < XEND_CONFIG_MIN_VERS_PVFB_NEWCONF) || - (hvm && xendConfigVersion < XEND_CONFIG_VERSION_3_1_0)) { + /* PV graphics for xen <= 3.0.4, or HVM graphics */ + if (hvm || (xendConfigVersion < XEND_CONFIG_MIN_VERS_PVFB_NEWCONF)) { if ((def->ngraphics == 1) && xenFormatSxprGraphicsOld(def->graphics[0], &buf, xendConfigVersion) < 0) @@ -2578,10 +2577,8 @@ xenFormatSxpr(virConnectPtr conn, if (xenFormatSxprAllPCI(def, &buf) < 0) goto error; - /* New style PV graphics config xen >= 3.0.4, - * or HVM graphics config xen >= 3.0.5 */ - if ((xendConfigVersion >= XEND_CONFIG_MIN_VERS_PVFB_NEWCONF && !hvm) || - (xendConfigVersion >= XEND_CONFIG_VERSION_3_1_0 && hvm)) { + /* New style PV graphics config xen >= 3.0.4 */ + if (!hmv && (xendConfigVersion >= XEND_CONFIG_MIN_VERS_PVFB_NEWCONF)) { if ((def->ngraphics == 1) && xenFormatSxprGraphicsNew(def->graphics[0], &buf) < 0) goto error; diff --git a/src/xenxs/xen_xm.c b/src/xenxs/xen_xm.c index 8e24fd52..d65e97a 100644 --- a/src/xenxs/xen_xm.c +++ b/src/xenxs/xen_xm.c @@ -1779,7 +1779,7 @@ virConfPtr xenFormatXM(virConnectPtr conn, } if (def->ngraphics == 1) { - if (xendConfigVersion < (hvm ?

[libvirt] [PATCH] test: fix build errors with gcc 4.7.0 and -O0
by Laine Stump 06 Apr '12

06 Apr '12

When building on Fedora 17 (which uses gcc 4.7.0) with -O0 in CFLAGS, three of the tests failed to compile. cputest.c and qemuxml2argvtest.c had non-static structs defined inside the macro that was being repeatedly invoked. Due to some so-far unidentified change in gcc, the stack space used by variables defined inside { } is not recovered/re-used when the block ends, so all these structs have become additive (this is the same problem worked around in commit cf57d345b). Fortunately, these two files could be fixed with a single line addition of "static" to the struct definition in the macro. virnettlscontexttest.c was a bit different, though. The structs were all defined inline as static already, but for some reason now take up space on the stack. The only reasonable solution here was to move all of the struct definitions outside of the function. In an ideal world, none of these changes should be necessary, but not knowing how long it will be until the gcc regressions are fixed, and since the code is just as correct after this patch as before, it makes sense to fix libvirt's build for -O0 while also reporting the gcc problem. --- tests/cputest.c | 2 +- tests/qemuxml2argvtest.c | 2 +- tests/virnettlscontexttest.c | 168 ++++++++++++++++++++++-------------------- 3 files changed, 91 insertions(+), 81 deletions(-) diff --git a/tests/cputest.c b/tests/cputest.c index 9928e5d..01db8f1 100644 --- a/tests/cputest.c +++ b/tests/cputest.c @@ -512,7 +512,7 @@ mymain(void) #define DO_TEST(arch, api, name, host, cpu, \ models, nmodels, preferred, result) \ do { \ - struct data data = { \ + static struct data data = { \ arch, api, host, cpu, models, \ models == NULL ?

[libvirt] [PATCH] test: fix segfault in networkxml2argvtest
by Laine Stump 05 Apr '12

05 Apr '12

This bug resolves https://bugzilla.redhat.com/show_bug.cgi?id=810100 rpm builds for i686 were failing with a segfault in networkxml2argvtest. Running under valgrind showed that a region of memory was being referenced after it had been freed (as the result of realloc - see the valgrind report in the BZ). The problem (in replaceTokens() - added in commit 22ec60, meaning this bug was in 0.9.10 and 0.9.11) was that the pointers token_start and token_end were being computed based on the value of *buf, then *buf was being realloc'ed (potentially moving it), then token_start and token_end were used without recomputing them to account for movement of *buf. The solution is to change the code so that token_start and token_end are offsets into *buf rather than pointers. This way there is only a single pointer to the buffer, and nothing needs readjusting after a realloc. (You may note that some uses of token_start/token_end didn't need to be changed to add in "*buf +" - that's because there ended up being a +*buf and -*buf which canceled each other out).

[libvirt] [test-API] RFC: Stabilization of libvirt-test-API
by Martin Kletzander 05 Apr '12

05 Apr '12

Hi everyone, following our minutes, I'd like to start a discussion on what should be done with libvirt-test-API so we can say it's stable and usable. I would like to stress out that everything mentioned here is just an opinion and I don't mean to talk down to someone as it may have seemed earlier. I think we should get some ideas from everyone, mostly QE as they will be (are) the ones using this the most (if I understood correctly), and then I'll be happy to help getting the code to the agreed status. I was thinking about this from the wrong way probably and changing the angle from what I look at it (and knowing there is some deadline) makes me think of few levels of changes, which when introduced, could speed up the test development and code understandability. So here are the things I would like to do definitely (the optional things follow later on): - fix hard-coded options into real options (e.g. commit 65449e) - fix some env_* and util* code (functions duplicated with different behavior) - fix or remove harmful and pointless code (at this point, when creating domain on remote machine, be prepared for the test to fail with any other user then root and with root, have backup of both local and remote '/root/.ssh' directories as the contents will be erased!) - fix method names for the {connect,domain,etc.}API (get_host_name vs. lookupByUUID etc.) The optional things: - get rid of classes in lib and make just few utility functions covering *only* the methods that do something else than call the same method in underlying class from the libvirt module. - get rid of the new exception (I don't see any other difference than in the name, which can make a difference in "except:" clause, but it's converted everywhere) - be able to share variables between tests (connection object and anything else) - introduce new config file for tests (.ini format, can be parsed by ConfigParser, same as env.cfg, define variables used throughout the test specifications - update the documentation - use some python code style (PEP-8?), make use of True/False, None - eliminate duplicated (and x-plicated) code (append_path in all the files, etc.) I have all of these figured out, so I'm willing to discuss all of them, but in most cases changing it in the current code seems very time-consumable to me. Please, feel free to comment on any of these, add yours, discuss, shout at me, etc. =) Regards, Martin P.S.: I don't see any point in sending my patches until some of these points are resolved as that could mean rewriting more code.

[libvirt] [PATCH V2] nwfilter: Add support for ipset
by Stefan Berger 05 Apr '12

05 Apr '12

This patch adds support for the recent ipset iptables extension to libvirt's nwfilter subsystem. Ipset allows to maintain 'sets' of IP addresses, ports and other packet parameters and allows for faster lookup (in the order of O(1) vs. O(n)) and rule evaluation to achieve higher throughput than what can be achieved with individual iptables rules. On the command line iptables supports ipset using iptables ... -m set --match-set <ipset name> <flags> -j ... where 'ipset name' is the name of a previously created ipset and flags is a comma-separated list of up to 6 flags. Flags use 'src' and 'dst' for selecting IP addresses, ports etc. from the source or destination part of a packet. So a concrete example may look like this: iptables -A INPUT -m set --match-set test src,src -j ACCEPT Since ipset management is quite complex, the idea was to leave ipset management outside of libvirt but still allow users to reference an ipset. The user would have to make sure the ipset is available once the VM is started so that the iptables rule(s) referencing the ipset can be created. Using XML to describe an ipset in an nwfilter rule would then look as follows: <rule action='accept' direction='in'> <all ipset='test' ipsetflags='src,src'/> </rule> The two parameters on the command line are also the two distinct XML attributes 'ipset' and 'ipsetflags'. FYI: Here is the man page for ipset: https://ipset.netfilter.org/ipset.man.html Regards, Stefan --- v2: - split ipset description into ipset and ipsetflags attribute - improved on documentation --- docs/formatnwfilter.html.in | 64 ++++++++++++++ docs/schemas/nwfilter.rng | 23 +++++ src/conf/nwfilter_conf.c | 135 +++++++++++++++++++++++++++++- src/conf/nwfilter_conf.h | 12 ++ src/nwfilter/nwfilter_ebiptables_driver.c | 71 +++++++++++++++ tests/nwfilterxml2xmlin/ipset-test.xml | 15 +++ tests/nwfilterxml2xmlout/ipset-test.xml | 15 +++ tests/nwfilterxml2xmltest.c | 2 8 files changed, 332 insertions(+), 5 deletions(-) Index: libvirt/src/conf/nwfilter_conf.c =================================================================== --- libvirt.orig/src/conf/nwfilter_conf.c +++ libvirt/src/conf/nwfilter_conf.c @@ -183,6 +183,8 @@ static const char dstportstart_str[] = " static const char dstportend_str[] = "dstportend";

[libvirt] patch for openvz driver to support vzctl 3.1
by Ilja Livenson 04 Apr '12

04 Apr '12

Hi, there was a recent update of vzctl from openvz, which made openvz driver crash: https://www.redhat.com/archives/libvirt-users/2012-March/msg00203.html Not sure about the correct procedure, but the patch is very simple and is shown here: https://bugzilla.redhat.com/show_bug.cgi?id=809895 . Basically, openvz dropped strict version numbering (3.1 vs 3.1.0), which caused parsing to fail. cheers, Ilya
