[libvirt] domjobabort return the same error in distinct cases
by Shahar Havivi 04 Dec '11

04 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 04 Dec '11

04 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 02 Dec '11

02 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

[libvirt] [PATCH 1/1] apparmor: allow tunnelled migrations.
by Serge Hallyn 02 Dec '11

02 Dec '11

The pathname for the pipe for tunnelled migration is unresolvable. The libvirt apparmor driver therefore refuses access, causing migration to fail. If we can't resolve the path, the worst that can happen is that we should have given permission to the file but didn't. Otherwise (especially since this is a /proc/$$/fd/N file) the file is already open and libvirt won't be refused access by apparmor anyway. Also adjust virt-aa-helper to allow access to the *.tunnelmigrate.dest.name files. Changelog: Dec 2: per jdstrand comment, also change the Error to a VIR_WARN. For more information, see https://launchpad.net/bugs/869553.

[libvirt] [PATCH] client: Check if other thread claims it has the buck before claiming it.
by Peter Krempa 02 Dec '11

02 Dec '11

Originaly, the code checked if another client is the queue and infered ownership of the buck from that. Commit fa9595003d043df9f2efe95521c008 added a separate variable to track the buck. That caused, that a new call might enter claiming it has the buck, while another thread was signalled to take the buck. This ends in two threads claiming they hold the buck and entering poll(). This happens due to a race on waking up threads on the client lock mutex. This caused multi-threaded clients to hang, most prominently visible and reproducible on python based clients, like virt-manager. This patch causes threads, that have been signalled to take the buck to re-check if buck is held by another thread. --- src/rpc/virnetclient.c | 9 ++++++++- 1 files changed, 8 insertions(+), 1 deletions(-) diff --git a/src/rpc/virnetclient.c b/src/rpc/virnetclient.c index 5165c8d..07d8a60 100644 --- a/src/rpc/virnetclient.c +++ b/src/rpc/virnetclient.c @@ -1545,6 +1545,7 @@ static int virNetClientIO(virNetClientPtr client, virNetClientCallQueue(&client->waitDispatch, thiscall); /* Check to see if another thread is dispatching */ +recheck: if (client->haveTheBuck) { char ignore = 1; @@ -1592,7 +1593,13 @@ static int virNetClientIO(virNetClientPtr client, goto cleanup; } - /* Grr, someone passed the buck onto us ... */ + /* Grr, someone might have passed the buck onto us ... */ + + /* We need to re-check if the buck has been passed to this thread + * as this thread might have been signalled to wake up, but the another + * call might acquire the lock before this thread manages to wake up. + * This could cause that two threads claim they have the buck */ + goto recheck; } VIR_DEBUG("We have the buck %p %p", client->waitDispatch, thiscall); -- 1.7.3.4
