[libvirt] [PATCH] Clarify the meaning of version in redirdev filters

[libvirt] [PATCH v3 00/15] Drop network driver lock
by Michal Privoznik 12 Mar '15

12 Mar '15

Well, this is interesting. I've turned the virNetworkObjList into using a virHash. And even though the performance in my testing (using the very same test program as in previous versions of the patch set) increased. Without these patches, the test program took 56s to finish. With these patches (that is with virHash table) it takes 46s, which is better. But previously, with network objects stored in flat array I was able to get somewhere around 23s! I wonder what may be the cause. NB, nearly all patches in the series have been ACKed already, but since I'm switching the virNetworkObjList internals, I'm posting them again.

[libvirt] [PATCH] virnetdev: fix build with old kernel
by Pavel Hrdina 11 Mar '15

11 Mar '15

Commit c9027d8f added a detection of NIC HW features, but some of them are not available in old kernel. Very old kernels lack enum ethtool_flags and even if this enum is present, not all values are available for all kernels. To be sure that we have everything in kernel that we need, we must check for existence of newest value which is ETH_FLAG_TXVLAN. Only then we can be sure that the feature detection can be successfully built.

[libvirt] [PATCH 0/4] parallels: fix different domain define parameters
by Maxim Nestratov 11 Mar '15

11 Mar '15

Actually our checking for unsupported parameters is too strict about cpumask, vcpupin and NUMA parameters and in general wrong. First of all, we do support cpumask and consequently we don't have to prevent domain definition in case cpumask is specified. Also we should allow vcpupin parameters if they don't contradict with common cpumask. NUMA checking was also wrong because def->numa is always allocated. Here we check that its content is not specified. Maxim Nestratov (4): parallels: cpumask support parallels: don't forget to unlock domain in parallelsDomainHasManagedSaveImage parallels: prevent domain define only if NUMA is really specified parallels: prevent domain define only if vcpupin is specified

[libvirt] [PATCH] {domain, network}_conf: disable autostart when deleting config
by Michael Chapman 11 Mar '15

11 Mar '15

Undefining a running, autostarted domain removes the autostart link, but dom->autostart is not cleared. If the domain is subsequently redefined, libvirt thinks it is already autostarted and will not create the link even if requested: # virsh dominfo example | grep Autostart Autostart: enable # ls /etc/libvirt/qemu/autostart/example.xml /etc/libvirt/qemu/autostart/example.xml # virsh undefine example Domain example has been undefined # virsh define example.xml Domain example defined from example.xml # virsh dominfo example | grep Autostart Autostart: enable # virsh autostart example Domain example marked as autostarted # ls /etc/libvirt/qemu/autostart/example.xml ls: cannot access /etc/libvirt/qemu/autostart/example.xml: No such file or directory This commit ensures dom->autostart is cleared whenever the config and autostart link (if present) are removed. The bridge network driver cleared this flag itself in networkUndefine. This commit moves this into virNetworkDeleteConfig for symmetry with virDomainDeleteConfig, and to ensure it is not missed in future network drivers.

[libvirt] CfP 10th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '15)
by VHPC 15 11 Mar '15

11 Mar '15

================================================================= CALL FOR PAPERS 10th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '15) held in conjunction with Euro-Par 2015, August 24-28, Vienna, Austria (Springer LNCS) ================================================================= Date: August 25, 2015 Workshop URL: http://vhpc.org Paper Submission Deadline: May 22, 2015 CALL FOR PAPERS Virtualization technologies constitute a key enabling factor for flexible resource management in modern data centers, cloud environments, and increasingly in HPC as well. Providers need to dynamically manage complex infrastructures in a seamless fashion for varying workloads and hosted applications, independently of the customers deploying software or users submitting highly dynamic and heterogeneous workloads. Thanks to virtualization, we have the ability to manage vast computing and networking resources dynamically and close to the marginal cost of providing the services, which is unprecedented in the history of scientific and commercial computing. Various virtualization technologies contribute to the overall picture in different ways: machine virtualization, with its capability to enable consolidation of multiple under-utilized servers with heterogeneous software and operating systems (OSes), and its capability to live-migrate a fully operating virtual machine (VM) with a very short downtime, enables novel and dynamic ways to manage physical servers; OS-level virtualization, with its capability to isolate multiple user-space environments and to allow for their co-existence within the same OS kernel, promises to provide many of the advantages of machine virtualization with high levels of responsiveness and performance; I/O Virtualization allows physical network adapters to take traffic from multiple VMs; network virtualization, with its capability to create logical network overlays that are independent of the underlying physical topology and IP addressing, provides the fundamental ground on top of which evolved network services can be realized with an unprecedented level of dynamicity and flexibility; These technologies have to be inter-mixed and integrated in an intelligent way, to support workloads that are increasingly demanding in terms of absolute performance, responsiveness and interactivity, and have to respect well-specified Service- Level Agreements (SLAs), as needed for industrial-grade provided services. Indeed, among emerging and increasingly interesting application domains for virtualization, we can find big-data application workloads in cloud infrastructures, interactive and real-time multimedia services in the cloud, including real-time big-data streaming platforms such as used in real-time analytics supporting nowadays a plethora of application domains. Distributed cloud infrastructures promise to offer unprecedented responsiveness levels for hosted applications, but that is only possible if the underlying virtualization technologies can overcome most of the latency impairments typical of current virtualized infrastructures (e.g., far worse tail-latency). The Workshop on Virtualization in High-Performance Cloud Computing (VHPC) aims to bring together researchers and industrial practitioners facing the challenges posed by virtualization in order to foster discussion, collaboration, mutual exchange of knowledge and experience, enabling research to ultimately provide novel solutions for virtualized computing systems of tomorrow. The workshop will be one day in length, composed of 20 min paper presentations, each followed by 10 min discussion sections, and lightning talks, limited to 5 minutes. Presentations may be accompanied by interactive demonstrations. TOPICS Topics of interest include, but are not limited to: - Virtualization in supercomputing environments, HPC clusters, cloud HPC and grids - Optimizations of virtual machine monitor platforms, hypervisors and OS-level virtualization - Hypervisor and network virtualization QoS and SLAs - Cloud based network and system management for SDN and NFV - Management, deployment and monitoring of virtualized environments - Performance measurement, modelling and monitoring of virtualized/cloud workloads - Programming models for virtualized environments - Cloud reliability, fault-tolerance, high-availability and security - Heterogeneous virtualized environments, virtualized accelerators, GPUs and co-processors - Optimized communication libraries/protocols in the cloud and for HPC in the cloud - Topology management and optimization for distributed virtualized applications - Cluster provisioning in the cloud and cloud bursting - Adaptation of emerging HPC technologies (high performance networks, RDMA, etc..) - I/O and storage virtualization, virtualization aware file systems - Job scheduling/control/policy in virtualized environments - Checkpointing and migration of VM-based large compute jobs - Cloud frameworks and APIs - Energy-efficient / power-aware virtualization Important Dates April 29, 2015 - Abstract registration May 22, 2015 - Full paper submission June 19, 2014 - Acceptance notification October 2, 2014 - Camera-ready version due August 25, 2014 - Workshop Date TPC CHAIR Michael Alexander (chair), TU Wien, Austria Anastassios Nanos (co-chair), NTUA, Greece Balazs Gerofi (co-chair), RIKEN Advanced Institute for Computational Science, Japan PROGRAM COMMITTEE Stergios Anastasiadis, University of Ioannina, Greece Costas Bekas, IBM Zurich Research Laboratory, Switzerland Jakob Blomer, CERN Ron Brightwell, Sandia National Laboratories, USA Roberto Canonico, University of Napoli Federico II, Italy Julian Chesterfield, OnApp, UK Patrick Dreher, MIT, USA William Gardner, University of Guelph, Canada Kyle Hale, Northwestern University, USA Marcus Hardt, Karlsruhe Institute of Technology, Germany Iftekhar Hussain, Infinera, USA Krishna Kant, Temple University, USA Eiji Kawai, National Institute of Information and Communications Technology, Japan Romeo Kinzler, IBM, Switzerland Kornilios Kourtis, ETH, Switzerland Nectarios Koziris, National Technical University of Athens, Greece Massimo Lamanna, CERN Che-Rung Roger Lee, National Tsing Hua University, Taiwan Helge Meinhard, CERN Jean-Marc Menaud, Ecole des Mines de Nantes France Christine Morin, INRIA, France Amer Qouneh, University of Florida, USA Seetharami Seelam, IBM Watson Research Center, USA Josh Simons, VMWare, USA Borja Sotomayor, University of Chicago, USA Kurt Tutschku, Blekinge Institute of Technology, Sweden Yasuhiro Watashiba, Osaka University, Japan Chao-Tung Yang, Tunghai University, Taiwan PAPER SUBMISSION-PUBLICATION Papers submitted to the workshop will be reviewed by at least two members of the program committee and external reviewers.

[libvirt] [PATCH] virQEMUCapsInitQMP: Don't dispose locked @vm
by Michal Privoznik 10 Mar '15

10 Mar '15

When creating qemu capabilities, a dummy virDomainObj is created just because our monitor code expects that. However, the object is created locked already. Then, under cleanup label, we simply unref the object which results in whole domain object to be disposed. The object lock is destroyed subsequently, but hey - it's still locked: ==24845== Thread #14's call to pthread_mutex_destroy failed ==24845== with error code 16 (EBUSY: Device or resource busy) ==24845== at 0x4C3024E: pthread_mutex_destroy (in /usr/lib64/valgrind/vgpreload_helgrind-amd64-linux.so) ==24845== by 0x531F72E: virMutexDestroy (virthread.c:83) ==24845== by 0x5302977: virObjectLockableDispose (virobject.c:237) ==24845== by 0x5302A89: virObjectUnref (virobject.c:265) ==24845== by 0x1DD37866: virQEMUCapsInitQMP (qemu_capabilities.c:3397) ==24845== by 0x1DD37CC6: virQEMUCapsNewForBinary (qemu_capabilities.c:3481) ==24845== by 0x1DD381E2: virQEMUCapsCacheLookup (qemu_capabilities.c:3609) ==24845== by 0x1DD30F8A: virQEMUCapsInitGuest (qemu_capabilities.c:744) ==24845== by 0x1DD31889: virQEMUCapsInit (qemu_capabilities.c:1020) ==24845== by 0x1DD7DD36: virQEMUDriverCreateCapabilities (qemu_conf.c:888) ==24845== by 0x1DDC57C0: qemuStateInitialize (qemu_driver.c:803) ==24845== by 0x53DC743: virStateInitialize (libvirt.c:777) ==24845== Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- src/qemu/qemu_capabilities.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index 8193805..dce40e0 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -3394,7 +3394,10 @@ virQEMUCapsInitQMP(virQEMUCapsPtr qemuCaps, if (monpath) ignore_value(unlink(monpath)); VIR_FREE(monpath); - virObjectUnref(vm); + if (vm) { + virObjectUnlock(vm); + virObjectUnref(vm); + } virObjectUnref(xmlopt); if (pid != 0) { -- 2.0.5

[libvirt] [PATCH 0/6] Follow-up patches for IOThread API/display
by John Ferlan 10 Mar '15

10 Mar '15

Based on jtomko's review of the IOThread series and my foray into the libvirt-perl bindings, these patches make the following adjustments: Patch 1 - Found while generating the virsh iothreadpin description, the vcpupin description had a few missing words Patch 2 - While working on the libvirt-perl bindings - I found I was a bit overaggressive with my GetIOThreadsInfo interface with regard to checking ReadOnly unnecessarily Patch 3 - Adjust the IOThread CPU Affnity algorithm based on jtomko's review comments Patch 4 - Fallout because I ran the patches through my Coverity checker. Patch 5 - Similar to IOThread - adjust the GetVcpuInfo CPU Affinity algorithm for the returned cpumap Patch 5 - Similar to IOThread - adjust the GetEmulatorInfo CPU Affinity algorithm for the returned cpumap John Ferlan (6): Fix syntax for vcpupin description Remove ReadOnly check for GetIOThreadsInfo qemu: Change/Fix IOThread CPU affinity bitmap manipulation qemu: Resolve Coverity CHECKED_RETURN issue qemu: Change qemuDomainGetVcpuPinInfo bitmap manipulation qemu: Change qemuDomainGetEmulatorPinInfo bitmap manipulation src/libvirt-domain.c | 1 - src/qemu/qemu_driver.c | 177 +++++++++++++++++++++---------------------------- tools/virsh.pod | 4 +- 3 files changed, 76 insertions(+), 106 deletions(-) -- 2.1.0
