[libvirt] [PATCH v4] storage: netfs and iscsi need option srcSpec for resource discovery
by Guannan Ren 02 Aug '12

02 Aug '12

The option 'srcSpec' to virsh command find-storage-pool-sources is optional for logical type of storage pool, but mandatory for netfs and iscsi type. When missing the option for netfs and iscsi, libvirt reports XML parsing error due to null string option srcSpec. before error: Failed to find any netfs pool sources error: (storage_source_specification):1: Document is empty (null) after: error: pool type 'iscsi' requires option --srcSpec for source discovery --- src/remote/remote_driver.c | 14 +------------- src/storage/storage_backend_fs.c | 13 +++++++++---- src/storage/storage_backend_iscsi.c | 7 +++++++ tools/virsh-pool.c | 6 ++++++ 4 files changed, 23 insertions(+), 17 deletions(-) diff --git a/src/remote/remote_driver.c b/src/remote/remote_driver.c index 9ac27b2..9354cb4 100644 --- a/src/remote/remote_driver.c +++ b/src/remote/remote_driver.c @@ -2648,23 +2648,11 @@ remoteFindStoragePoolSources (virConnectPtr conn, remote_find_storage_pool_sources_args args; remote_find_storage_pool_sources_ret ret; struct private_data *priv = conn->storagePrivateData; - const char *emptyString = ""; remoteDriverLock(priv); args.type = (char*)type; - /* - * I'd think the following would work here: - * args.srcSpec = (char**)&srcSpec; - * since srcSpec is a remote_string (not a remote_nonnull_string). - * - * But when srcSpec is NULL, this yields: - * libvir: Remote error : marshaling args - * - * So for now I'm working around this by turning NULL srcSpecs - * into empty strings. - */ - args.srcSpec = srcSpec ?

[libvirt] [PATCH] shutting down guest vms on host shutdown does not work
by Gerd v. Egidy 02 Aug '12

02 Aug '12

Hi, I originally postet this into the Fedora bugzilla https://bugzilla.redhat.com/show_bug.cgi?id=843836 but was asked by Eric to post it here for review. Currently gracefully shutting down guest vms on host shutdown does not work on Fedora 17, the guests are killed hard on system shutdown. I use: fedora-release-17-1.noarch libvirt-client-0.9.11.4-3.fc17.x86_64 systemd-44-17.fc17.x86_64 But I have looked into current libvirt git and see the same code there so I don't think it is any different with current git, but I have not verified this. The reason is systemd considers libvirt-guests.service to be stopped when the system is running: $ systemctl status libvirt-guests.service libvirt-guests.service - Suspend Active Libvirt Guests Loaded: loaded (/usr/lib/systemd/system/libvirt-guests.service; enabled) Active: deactivating (stop) since Fri, 27 Jul 2012 15:47:31 +0200; 2min 48s ago Process: 1085 ExecStart=/etc/init.d/libvirt-guests start (code=exited, status=0/SUCCESS) Control: 1150 (libvirt-guests) CGroup: name=systemd:/system/libvirt-guests.service └ control ├ 1150 /bin/sh /etc/init.d/libvirt-guests stop └ 2257 sleep 1 libvirt-guests.service is defined as type "simple" in systemd (the default). That means systemd will shut down the service when the start executable is terminated after starting is done. Systemd will not call stop again on system shutdown because it thinks it is already stopped. The solution is to define it as type "oneshot" and set the flag "RemainAfterExit". Then systemd will consider the service as active after startup and will call the stop function on host shutdown. With the attached patch everything works as expected. Please consider merging. Kind regards, Gerd

[libvirt] [PATCH] daemon: Fix crash in virTypedParameterArrayClear
by Jiri Denemark 02 Aug '12

02 Aug '12

Daemon uses the following pattern when dispatching APIs with typed parameters: VIR_ALLOC_N(params, nparams); virDomain*(dom, params, &nparams, flags); virTypedParameterArrayClear(params, nparams); In case nparams was originally set to 0, virDomain* API would fill it with the number of typed parameters it can provide and we would use this number (rather than zero) to clear params. Because VIR_ALLOC* returns non-NULL pointer even if size is 0, the code would end up walking through random memory. If we were lucky enough and the memory contained 7 (VIR_TYPED_PARAM_STRING) at the right place, we would try to free a random pointer and crash. Let's make sure params stays NULL when nparams is 0. --- daemon/remote.c | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/daemon/remote.c b/daemon/remote.c index 80626a2..d25717c 100644 --- a/daemon/remote.c +++ b/daemon/remote.c @@ -989,7 +989,7 @@ remoteDispatchDomainGetSchedulerParameters(virNetServerPtr server ATTRIBUTE_UNUS virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("nparams too large")); goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) + if (nparams && VIR_ALLOC_N(params, nparams) < 0) goto no_memory; if (!(dom = get_nonnull_domain(priv->conn, args->dom))) @@ -1098,7 +1098,7 @@ remoteDispatchDomainGetSchedulerParametersFlags(virNetServerPtr server ATTRIBUTE virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("nparams too large")); goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) + if (nparams && VIR_ALLOC_N(params, nparams) < 0) goto no_memory; if (!(dom = get_nonnull_domain(priv->conn, args->dom))) @@ -1279,7 +1279,7 @@ remoteDispatchDomainBlockStatsFlags(virNetServerPtr server ATTRIBUTE_UNUSED, virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("nparams too large")); goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) { + if (nparams && VIR_ALLOC_N(params, nparams) < 0) { virReportOOMError(); goto cleanup; } @@ -1753,7 +1753,7 @@ remoteDispatchDomainGetMemoryParameters(virNetServerPtr server ATTRIBUTE_UNUSED, virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("nparams too large")); goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) { + if (nparams && VIR_ALLOC_N(params, nparams) < 0) { virReportOOMError(); goto cleanup; } @@ -1818,7 +1818,7 @@ remoteDispatchDomainGetNumaParameters(virNetServerPtr server ATTRIBUTE_UNUSED, virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("nparams too large")); goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) { + if (nparams && VIR_ALLOC_N(params, nparams) < 0) { virReportOOMError(); goto cleanup; } @@ -1883,7 +1883,7 @@ remoteDispatchDomainGetBlkioParameters(virNetServerPtr server ATTRIBUTE_UNUSED, virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("nparams too large")); goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) { + if (nparams && VIR_ALLOC_N(params, nparams) < 0) { virReportOOMError(); goto cleanup; } @@ -2143,7 +2143,7 @@ remoteDispatchDomainGetBlockIoTune(virNetServerPtr server ATTRIBUTE_UNUSED, goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) { + if (nparams && VIR_ALLOC_N(params, nparams) < 0) { virReportOOMError(); goto cleanup; } @@ -3646,7 +3646,7 @@ remoteDispatchDomainGetInterfaceParameters(virNetServerPtr server ATTRIBUTE_UNUS virReportError(VIR_ERR_INTERNAL_ERROR, "%s", _("nparams too large")); goto cleanup; } - if (VIR_ALLOC_N(params, nparams) < 0) { + if (nparams && VIR_ALLOC_N(params, nparams) < 0) { virReportOOMError(); goto cleanup; } -- 1.7.11.1
