[libvirt] [PATCH 0/2] Expose virNodeGetCPUStats and virNodeGetMemoryStats in python
by Peter Krempa 05 Dec '11

05 Dec '11

These patches add two API functions to the libvirt python bindings, that were missing. The constants denoting a summary stat value instead of a separate per-node values was declared using a preprocessor macro: ... #define VIR_NODE_MEMORY_STATS_ALL_CELLS (-1) #define VIR_NODE_CPU_STATS_ALL_CPUS (-1) ... This inhibits automatic generation of these constants in the automaticaly generated python library code. If this change is too controversial, there's another option: Including these constants in the python library (using libvirt-override.py). Please let me know which of those options you prefer. Thanks Peter Peter Krempa (2): python: Expose binding for virNodeGetCPUStats() python: Expose binding for virNodeGetMemoryStats() include/libvirt/libvirt.h.in | 12 +++-- - change macro definitions to enums python/libvirt-override-api.xml | 14 ++++++ - add doc's about newly added functions python/libvirt-override.c | 95 +++++++++++++++++++++++++++++++++++++++ - add code for calling those functions and reclaiming return values. 3 files changed, 117 insertions(+), 4 deletions(-) -- 1.7.3.4

[libvirt] domjobabort return the same error in distinct cases
by Shahar Havivi 05 Dec '11

05 Dec '11

Hi, I am using the python api: domain.abortjob(), if there is no job I get exception with error code: VIR_ERR_OPERATION_INVALID with the error message: 'Requested operation is not valid: no job is active on the domain' when there is a job I get the same exception code with the same error message, in addition I get another exception: libvirtError ('virDomainMigrateToURI2() failed', dom=self) libvirtError: operation failed: migration job: canceled by client the migration thread is throwing as well: libvirtError ('virDomainMigrateToURI2() failed', dom=self) libvirtError: operation failed: migration job: canceled by client Should the same error should be for this two cases?

[libvirt] implementing locking with libvirt on ubuntu
by Upendra Moturi 05 Dec '11

05 Dec '11

Hi I am trying to implement locking i,e two vms are not started with same disk on ubuntu. Using libvirt 0.9.7 (Installed it from source) qemu-kvm 0.14.1 kernel 3.0.0-13-server Steps followed while installing from source cd libvirt-0.9.7 ./configure make make install I found that sanlock or virtlockd (fcntl) daemons can do that,but not able implement it. I dont find virtlockd daemon running. >From below link http://www.redhat.com/archives/libvir-list/2011-July/msg00337.html it is said to create lockd directory under /var/lib/libvirt I dont find this directory after installation from source Am i missing something ? Please guide me in implementing locking on ubuntu. -- Thanks and Regards, Upendra.M

[libvirt] [PATCH] build: fix build at -O2 on rawhide
by Eric Blake 03 Dec '11

03 Dec '11

I had previously tested commit 059d746 with -O intentionally omitted from my CFLAGS; but that means that I missed out on this warning from gcc 4.6.2 when optimizations are enabled: util/buf.c: In function 'virBufferGetIndent': util/buf.c:86:1: error: function might be candidate for attribute 'pure' [-Werror=suggest-attribute=pure] While it is probably a good idea to add the attributes and silence this warning, it's also invasive; 'make -k' found more than 75 such complaints. And it doesn't help that gcc 4.6.2 is still buggy (coreutils reported a case where gcc 4.6.2 incorrectly suggested marking a function pure that incremented a global variable; fixed in gcc 4.7). So the best fix for now is to disable the warning. It also doesn't help that I stumbled across another problem - gcc documents that -Wsuggest-attribute=pure only warns if you use -O, or if you use -fipa-pure-const. But in practice, when I omitted -O but added -fipa-pure-const, the warnings are fickle - I got warnings for simple compilation that disappeared when I also added -fPIC. And the way libtool compiles things is with -fPIC first, then without -fPIC but with errors sent to /dev/null - which meant that without disabling -Wsuggest-attribute=pure, I got a compile error with no message. :( See http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10197 * m4/virt-compile-warnings.m4 (LIBVIRT_COMPILE_WARNINGS): Silence -Wsuggest-attribute warnings for now. --- Pushing under the build-breaker rule. m4/virt-compile-warnings.m4 | 8 ++++++++ 1 files changed, 8 insertions(+), 0 deletions(-) diff --git a/m4/virt-compile-warnings.m4 b/m4/virt-compile-warnings.m4 index 213b3db..34a89c9 100644 --- a/m4/virt-compile-warnings.m4 +++ b/m4/virt-compile-warnings.m4 @@ -116,2 +116,2 @@ AC_DEFUN([LIBVIRT_COMPILE_WARNINGS],[ gl_WARN_ADD([-fdiagnostics-show-option]) gl_WARN_ADD([-funit-at-a-time]) + # Need -fipa-pure-const in order to make -Wsuggest-attribute=pure + # fire even without -O. + gl_WARN_ADD([-fipa-pure-const]) + # We should eventually enable this, but right now there are at + # least 75 functions triggering warnings. + gl_WARN_ADD([-Wno-suggest-attribute=pure]) + gl_WARN_ADD([-Wno-suggest-attribute=const]) + if test "$enable_compile_warnings" = "error" then gl_WARN_ADD([-Werror]) -- 1.7.7.3
