[libvirt] [PATCH] storage: Revert volume obj list updating after volume creation (4749d82a)
by Erik Skultety 09 Jul '15

09 Jul '15

This patch reverts commit 4749d82a which tried to tweak the logic in volume creation. We did realloc and update our object list before we executed volume building within a specific storage backend. If that failed, we had to update (again) our object list to the original state as it was before the build and delete the volume from the pool (even though it didn't exist - this truly depends on the backend). I misunderstood the base idea to be able to poll the status of the volume creation using vol-info. After commit 4749d82a this wasn't possible anymore, although no BZ has been reported yet. Commit 4749d82a also claimed to fix https://bugzilla.redhat.com/show_bug.cgi?id=1223177, but commit c8be606b of the same series as 4749d82ad (which was more of a refactor than a fix) fixes the same issue so the revert should be pretty straightforward. Further more, BZ https://bugzilla.redhat.com/show_bug.cgi?id=1241454 can be fixed with this revert. --- src/storage/storage_driver.c | 28 ++++++++++++++++++---------- 1 file changed, 18 insertions(+), 10 deletions(-) diff --git a/src/storage/storage_driver.c b/src/storage/storage_driver.c index d3cdbc5..b67a5d8 100644 --- a/src/storage/storage_driver.c +++ b/src/storage/storage_driver.c @@ -1803,6 +1803,9 @@ storageVolCreateXML(virStoragePoolPtr obj, goto cleanup; } + if (VIR_REALLOC_N(pool->volumes.objs, + pool->volumes.count+1) < 0) + goto cleanup; if (!backend->createVol) { virReportError(VIR_ERR_NO_SUPPORT, @@ -1817,6 +1820,14 @@ storageVolCreateXML(virStoragePoolPtr obj, if (backend->createVol(obj->conn, pool, voldef) < 0) goto cleanup; + pool->volumes.objs[pool->volumes.count++] = voldef; + volobj = virGetStorageVol(obj->conn, pool->def->name, voldef->name, + voldef->key, NULL, NULL); + if (!volobj) { + pool->volumes.count--; + goto cleanup; + } + if (VIR_ALLOC(buildvoldef) < 0) { voldef = NULL; goto cleanup; @@ -1845,18 +1856,15 @@ storageVolCreateXML(virStoragePoolPtr obj, voldef->building = false; pool->asyncjobs--; - if (buildret < 0) + if (buildret < 0) { + VIR_FREE(buildvoldef); + storageVolDeleteInternal(volobj, backend, pool, voldef, + 0, false); + voldef = NULL; goto cleanup; - } - - if (VIR_REALLOC_N(pool->volumes.objs, - pool->volumes.count+1) < 0) - goto cleanup; + } - pool->volumes.objs[pool->volumes.count++] = voldef; - if (!(volobj = virGetStorageVol(obj->conn, pool->def->name, voldef->name, - voldef->key, NULL, NULL))) - goto cleanup; + } if (backend->refreshVol && backend->refreshVol(obj->conn, pool, voldef) < 0) -- 1.9.3

[libvirt] [PATCH v4 0/3] Allow PCI virtio on ARM "virt" machine
by Pavel Fedin 09 Jul '15

09 Jul '15

Virt machine in qemu since v2.3.0 has PCI generic host controller, and can use PCI devices. This provides performance improvement as well as vhost-net with irqfd support for virtio-net. However libvirt currently does not allow ARM virt machine to have PCI devices. This patchset adds the necessary support. Changes since v3: - Capability is based not on qemu version but on support of "gpex-pcihost" device by qemu - Added a workaround, allowing to pass "make check". The problem is that test suite does not build capabilities cache. Unfortunately this means that correct unit-test for the new functionality currently cannot be written. Test suite framework needs to be improved. Changes since v2: Complete rework, use different approach - Correctly model PCI Express bus on the machine. It is now possible to explicitly specify <address-type='pci'> with attributes. This allows to attach not only virtio, but any other PCI device to the model. - Default is not changed and still mmio, for backwards compatibility with existing installations. PCI bus has to be explicitly specified. - Check for the capability in correct place, in v2 it actually did not work Changes since v1: - Added capability based on qemu version number - Recognize also "virt-" prefix Pavel Fedin (3): Introduce QEMU_CAPS_OBJECT_GPEX Add PCI-Express root to ARM virt machine Build correct command line for PCI NICs on ARM src/qemu/qemu_capabilities.c | 2 ++ src/qemu/qemu_capabilities.h | 1 + src/qemu/qemu_command.c | 3 ++- src/qemu/qemu_domain.c | 17 +++++++++++++---- 4 files changed, 18 insertions(+), 5 deletions(-) -- 1.9.5.msysgit.0

[libvirt] [PATCH] conf: Don't allow duplicated targets regardless of bus
by John Ferlan 09 Jul '15

09 Jul '15

https://bugzilla.redhat.com/show_bug.cgi?id=1142631 Commit id 'e0e290552' added a check to determine if the same bus had the same target value. It seems that's not quite good enough as the check should check the target name value regardless of bus type.

[libvirt] [PATCH v3 0/4] Followup for unpriv_sgio changes
by John Ferlan 09 Jul '15

09 Jul '15

v2: http://www.redhat.com/archives/libvir-list/2015-July/msg00204.html I pushed the first 3 patches already since they were ACK'd This is patches 4-8 adjusted for code review comments Patch1 (former patch4) - change the function to use qemuCheckUnprivSGIO not qemuCheckUnprivSGIO. Also used a -1 or -2 return value for handling the mismatched sgio setting error which requires the caller to have a message including the device with the issue Former patch 5 abandoned Patch2 (former patch6) - completely removed qemuGetSharedHostdevKey and replaced with inline code. Although this looks odd now, a future patch will use the device name on the add side. Patch3 (former patch7) - restored the {} in the right place Patch4 (former patch8) - remove val initialization - already ACK'd, but easier for me to just keep in the current order. Former patches 9 & 10 - keeping separate for downstream John Ferlan (4): qemu: Refactor qemuCheckSharedDisk to create qemuCheckUnprivSGIO qemu: Inline qemuGetHostdevPath qemu: Refactor qemuSetUnprivSGIO return values qemu: Fix integer/boolean logic in qemuSetUnprivSGIO src/qemu/qemu_conf.c | 151 ++++++++++++++++++++++++++++++--------------------- 1 file changed, 89 insertions(+), 62 deletions(-) -- 2.1.0

[libvirt] [PATCH] qemu: fix no error settings if fail to find a disk match path

When we use get blockjob info to a unexist disk path, we will get a error like this: # virsh blockjob r7 vdc error: An error occurred, but the cause is unknown This is because we do not set the error when jump to endjob.
