[libvirt] [PATCH 0/6] add fields to virStorageFileMetadata
by Eric Blake 09 Apr '14

09 Apr '14

I'm finally happy enough that I'm populating new fields correctly; I still need to visit uses of the old fields to swap them over to using the new fields before I can finally merge the virStorageFileMetadata and virStorageSource structs into one. I posted an RFC version of patch 4 earlier: https://www.redhat.com/archives/libvir-list/2014-April/msg00047.html since then, I've cleaned things up so that it passes the testsuite the first time through.

[libvirt] [PATCH] storage: Don't update pool available/allocation pool if vol-create-as fails
by John Ferlan 09 Apr '14

09 Apr '14

https://bugzilla.redhat.com/show_bug.cgi?id=1024159 If adding a volume to a storage pool fails during the CreateXML or CreateXMLFrom API's, we don't want to adjust the available and allocation values for the storage pool during storageVolDelete since we haven't adjusted the values for the create. Refactor storageVolDelete() a bit to create a storageVolDeleteInternal() which will handle the primary deletion activities. Add a parameter updateMeta which will signify whether to update the values or not. Adjust the calls from CreateXML and CreateXMLFrom to directly call the DeleteInternal with the pool lock held. This does bypass the call to virStorageVolDeleteEnsureACL(). Signed-off-by: John Ferlan <jferlan(a)redhat.com> --- I did try to make storageVolDelete() just be a shim to storageVolDeleteInternal(), but ran afoul of check-aclrules.pl since the EnsureAcl wasn't in storageVolDelete(). src/storage/storage_driver.c | 83 +++++++++++++++++++++++++++----------------- 1 file changed, 52 insertions(+), 31 deletions(-) diff --git a/src/storage/storage_driver.c b/src/storage/storage_driver.c index 2f98f78..6b14b1b 100644 --- a/src/storage/storage_driver.c +++ b/src/storage/storage_driver.c @@ -1553,6 +1553,51 @@ storageVolLookupByPath(virConnectPtr conn, static int +storageVolDeleteInternal(virStorageVolPtr obj, + virStorageBackendPtr backend, + virStoragePoolObjPtr pool, + virStorageVolDefPtr vol, + unsigned int flags, + bool updateMeta) +{ + size_t i; + int ret = -1; + + if (!backend->deleteVol) { + virReportError(VIR_ERR_NO_SUPPORT, + "%s", _("storage pool does not support vol deletion")); + + goto cleanup; + } + + if (backend->deleteVol(obj->conn, pool, vol, flags) < 0) + goto cleanup; + + /* Update pool metadata - don't update meta data from error paths + * in this module since the allocation/available weren't adjusted yet + */ + if (updateMeta) { + pool->def->allocation -= vol->target.allocation; + pool->def->available += vol->target.allocation; + } + + for (i = 0; i < pool->volumes.count; i++) { + if (pool->volumes.objs[i] == vol) { + VIR_INFO("Deleting volume '%s' from storage pool '%s'", + vol->name, pool->def->name); + virStorageVolDefFree(vol); + + VIR_DELETE_ELEMENT(pool->volumes.objs, i, pool->volumes.count); + break; + } + } + ret = 0; + + cleanup: + return ret; +} + +static int storageVolDelete(virStorageVolPtr obj, unsigned int flags) { @@ -1560,7 +1605,6 @@ storageVolDelete(virStorageVolPtr obj, virStoragePoolObjPtr pool; virStorageBackendPtr backend; virStorageVolDefPtr vol = NULL; - size_t i; int ret = -1; storageDriverLock(driver); @@ -1602,30 +1646,9 @@ storageVolDelete(virStorageVolPtr obj, goto cleanup; } - if (!backend->deleteVol) { - virReportError(VIR_ERR_NO_SUPPORT, - "%s", _("storage pool does not support vol deletion")); - - goto cleanup; - } - - if (backend->deleteVol(obj->conn, pool, vol, flags) < 0) + if (storageVolDeleteInternal(obj, backend, pool, vol, flags, true) < 0) goto cleanup; - /* Update pool metadata */ - pool->def->allocation -= vol->target.allocation; - pool->def->available += vol->target.allocation; - - for (i = 0; i < pool->volumes.count; i++) { - if (pool->volumes.objs[i] == vol) { - VIR_INFO("Deleting volume '%s' from storage pool '%s'", - vol->name, pool->def->name); - virStorageVolDefFree(vol); - - VIR_DELETE_ELEMENT(pool->volumes.objs, i, pool->volumes.count); - break; - } - } ret = 0; cleanup: @@ -1634,7 +1657,6 @@ storageVolDelete(virStorageVolPtr obj, return ret; } - static virStorageVolPtr storageVolCreateXML(virStoragePoolPtr obj, const char *xmldesc, @@ -1738,9 +1760,9 @@ storageVolCreateXML(virStoragePoolPtr obj, voldef = NULL; if (buildret < 0) { - virStoragePoolObjUnlock(pool); - storageVolDelete(volobj, 0); - pool = NULL; + storageVolDeleteInternal(volobj, backend, pool, buildvoldef, + 0, false); + buildvoldef = NULL; goto cleanup; } @@ -1908,7 +1930,6 @@ storageVolCreateXMLFrom(virStoragePoolPtr obj, origvol->building = 0; newvol->building = 0; allocation = newvol->target.allocation; - newvol = NULL; pool->asyncjobs--; if (origpool) { @@ -1918,11 +1939,11 @@ storageVolCreateXMLFrom(virStoragePoolPtr obj, } if (buildret < 0) { - virStoragePoolObjUnlock(pool); - storageVolDelete(volobj, 0); - pool = NULL; + storageVolDeleteInternal(volobj, backend, pool, newvol, 0, false); + newvol = NULL; goto cleanup; } + newvol = NULL; /* Updating pool metadata */ pool->def->allocation += allocation; -- 1.9.0

[libvirt] [PATCH 1/1] Set pci-ohci as the USB default controller for PPC64.
by Li Zhang 09 Apr '14

From: Li Zhang <zhlcindy(a)linux.vnet.ibm.com> PPC64 prefers to set pci-ohci controller as default USB controller. Currently, libvirt is using legacy USB controller as default.

Some enhancements and fixes with domain management. 1. Create stub for domainResume. Since bhyve does not support suspending, this one works a little different. If domain is already running, it reports success, but fails in all other cases. 2. add domainCreateXML routine 3. Fix persistency: when domain is not persistent, it should be forgotten upon domainDestroy.

[libvirt] How to pass -no-kvm-irqchip to KVM/QEMU guests
by Brody Wong 09 Apr '14

09 Apr '14

Hi, experts, I am using libvirt 0.10.2, and doing some tests against guest IO performance. Can I have a way to pass -no-kvm-irqchip in libvirt xml files to qemu-kvm? I did some search in google, it hits: http://www.redhat.com/archives/libvir-list/2009-September/msg00495.html But it seems it does not work on CentOS, after I used this wrapper script, qemu-kvm will crash.. and I did not find libvirt upstream solved this problem, is there anther way to solve this? Thanks a lot.
