[libvirt] [PATCH] qemu: don't refuse to undefine a guest with NVRAM file
by Daniel P. Berrange 24 May '16

24 May '16

The undefine operation should always be allowed to succeed regardless of whether any NVRAM file exists. ie we should not force the application to use the VIR_DOMAIN_UNDEFINE_NVRAM flag. It is valid for the app to decide it wants the NVRAM file left on disk, in the same way that disk images are left on disk at undefine. --- src/qemu/qemu_driver.c | 20 +++++++------------- 1 file changed, 7 insertions(+), 13 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index bec05d4..302bf48 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -6985,19 +6985,13 @@ qemuDomainUndefineFlags(virDomainPtr dom, if (!virDomainObjIsActive(vm) && vm->def->os.loader && vm->def->os.loader->nvram && - virFileExists(vm->def->os.loader->nvram)) { - if (!(flags & VIR_DOMAIN_UNDEFINE_NVRAM)) { - virReportError(VIR_ERR_OPERATION_INVALID, "%s", - _("cannot delete inactive domain with nvram")); - goto cleanup; - } - - if (unlink(vm->def->os.loader->nvram) < 0) { - virReportSystemError(errno, - _("failed to remove nvram: %s"), - vm->def->os.loader->nvram); - goto cleanup; - } + virFileExists(vm->def->os.loader->nvram) && + (flags & VIR_DOMAIN_UNDEFINE_NVRAM) && + (unlink(vm->def->os.loader->nvram) < 0)) { + virReportSystemError(errno, + _("failed to remove nvram: %s"), + vm->def->os.loader->nvram); + goto cleanup; } if (virDomainDeleteConfig(cfg->configDir, cfg->autostartDir, vm) < 0) -- 2.1.0

[libvirt] [PATCH v2 0/8] PCI Multifunction device hotplug support
by Shivaprasad G Bhat 23 May '16

23 May '16

V1 was posted here. http://www.redhat.com/archives/libvir-list/2016-May/msg01178.html Changes from V1 Fixed couple of issues in address validation and assignment. Added Rollback of the hotplug if anything fails in between. Removed Patch 6 completely as it exposed way too many bugs. Changed the approach a bit by introducing 2 new patches which take care of hostdevice preparation and help reverting. Todo: 1) Hardening the hotplug checks to disallow multifunction cards hotplug as though they are single function cards. 2) Documentation update. 3) Test cases. 4) Should the events be delayed till all the functions are hotplugged/unplugged? Something can fail and the revert may not be possible Or the guest may refuse to free the device. If we show events for those which got free, the rest of them may never be freed and also that may not be usable by guest if the function 0 is not part of it. Need to think more on this. Any suggestions ? --- Shivaprasad G Bhat (8): Revert "prevent hot unplugging multi function PCI device" Release address in function granularity than slot Validate address in virDomainPCIAddressReleaseAddr Introduce PCI Multifunction device parser Introduce virDomainPCIMultifunctionDeviceAddressAssign Separate the hostdevice preparation and checks to a new funtion Move the detach of PCI device to the beginnging of live hotplug Enable PCI Multifunction hotplug/unplug src/conf/domain_addr.c | 239 ++++++++++++++++++++++++++++-- src/conf/domain_addr.h | 4 src/conf/domain_conf.c | 236 +++++++++++++++++++++++++++++ src/conf/domain_conf.h | 22 +++ src/libvirt_private.syms | 5 + src/qemu/qemu_domain_address.c | 2 src/qemu/qemu_driver.c | 321 ++++++++++++++++++++++++++++++++-------- src/qemu/qemu_hotplug.c | 161 ++++++++------------ src/qemu/qemu_hotplug.h | 5 + 9 files changed, 818 insertions(+), 177 deletions(-) -- Signature

[libvirt] [PATCH] storage: do not clear vols before volume upload
by Ján Tomko 23 May '16

23 May '16

Commit 5e54361c added virStoragePoolObjClearVols before refreshPool to prevent duplicate volume entries. However it is not needed here because we're not refreshing the pool yet, just checking for the existence of the refresh callback. The actual refresh is done via virStorageVolFDStreamCloseCb in virStorageVolPoolRefreshThread, which already calls virStoragePoolObjClearVols. --- src/storage/storage_driver.c | 1 - 1 file changed, 1 deletion(-) diff --git a/src/storage/storage_driver.c b/src/storage/storage_driver.c index ce31e38..eb5f688 100644 --- a/src/storage/storage_driver.c +++ b/src/storage/storage_driver.c @@ -2353,15 +2353,14 @@ storageVolUpload(virStorageVolPtr obj, /* If we have a refreshPool, use the callback routine in order to * refresh the pool after the volume upload stream closes.

Hmm, maybe something like networkGetDHCPLeasesAll() is a better name. Regardless of the name, I see that other functions in bridge_driver.c take a virDomainDefPtr, so maybe extracting the code to bridge_driver.c is acceptable. Laine (cc'd) is generally regarded as the libvirt networking expert :-). Let's see if he has an opinion. Regards, Jim
