[libvirt] [PATCH 0/3] Miscellaneous Coverity & Valgrind changes
by John Ferlan 23 Jul '13

23 Jul '13

These patches resolve a Coverity warning and a found Valgrind leak. Added more patterns to the .valgrind.supp file to suppress the commandtests and seclabeltest output. This will thus result in a mostly clean valgrind run. All that remains is a hotplugtest failure, which some patches were posted: https://www.redhat.com/archives/libvir-list/2013-July/msg01156.html and https://www.redhat.com/archives/libvir-list/2013-July/msg01158.html but did not completely resolve the failures.

[libvirt] [PATCH V3] add console support in libxl
by Bamvor Jian Zhang 23 Jul '13

23 Jul '13

this patch introduce the console api in libxl driver for both pv and hvm guest. and import and update the libxlMakeChrdevStr function which was deleted in commit dfa1e1dd. Signed-off-by: Bamvor Jian Zhang <bjzhang(a)suse.com> --- Changes since V2: 1), forbid parallel configure because libxl do not support it 2), only support one serial on libxl driver. 3), also remove console code in libxl driver, AFAICS serial is enough for connecting to libxl console. changes since V1: 1), add virDomainOpenConsoleEnsureACL 3), remove virReportOOMErrorFull when virAsprintf fail. 4), change size_t for non-nagetive number in libxlDomainOpenConsole size_t i; size_t num = 0; 5), fix for make check (1), replace virAsprintf with VIR_STRDUP in two places (2), delete space. src/libxl/libxl_conf.c | 100 +++++++++++++++++++++++++++++++++++++++++++++++ src/libxl/libxl_conf.h | 3 ++ src/libxl/libxl_driver.c | 87 +++++++++++++++++++++++++++++++++++++++++ 3 files changed, 190 insertions(+) diff --git a/src/libxl/libxl_conf.c b/src/libxl/libxl_conf.c index 4a0fba9..539d537 100644 --- a/src/libxl/libxl_conf.c +++ b/src/libxl/libxl_conf.c @@ -331,6 +331,90 @@ error: } static int +libxlMakeChrdevStr(virDomainChrDefPtr def, char **buf) +{ + const char *type = virDomainChrTypeToString(def->source.type); + int ret; + + if (!type) { + virReportError(VIR_ERR_INTERNAL_ERROR, + "%s", _("unexpected chr device type")); + return -1; + } + + switch (def->source.type) { + case VIR_DOMAIN_CHR_TYPE_NULL: + case VIR_DOMAIN_CHR_TYPE_STDIO: + case VIR_DOMAIN_CHR_TYPE_VC: + case VIR_DOMAIN_CHR_TYPE_PTY: + if (VIR_STRDUP(*buf, type) < 0) + return -1; + break; + + case VIR_DOMAIN_CHR_TYPE_FILE: + case VIR_DOMAIN_CHR_TYPE_PIPE: + if (virAsprintf(buf, "%s:%s", type, + def->source.data.file.path) < 0) + return -1; + break; + + case VIR_DOMAIN_CHR_TYPE_DEV: + if (VIR_STRDUP(*buf, def->source.data.file.path) < 0) + return -1; + break; + + case VIR_DOMAIN_CHR_TYPE_UDP: { + const char *connectHost = def->source.data.udp.connectHost; + const char *bindHost = def->source.data.udp.bindHost; + const char *bindService = def->source.data.udp.bindService; + + if (connectHost == NULL) + connectHost = ""; + if (bindHost == NULL) + bindHost = ""; + if (bindService == NULL) + bindService = "0"; + + ret = virAsprintf(buf, "udp:%s:%s@%s:%s", + connectHost, + def->source.data.udp.connectService, + bindHost, + bindService); + if (ret < 0) + return -1; + break; + + } + case VIR_DOMAIN_CHR_TYPE_TCP: + if (def->source.data.tcp.protocol == VIR_DOMAIN_CHR_TCP_PROTOCOL_TELNET) + ret = virAsprintf(buf, "telnet:%s:%s%s", + def->source.data.tcp.host, + def->source.data.tcp.service, + def->source.data.tcp.listen ?

[libvirt] KVM Forum 2013 Call for Participation - Extended to August 4th
by Anthony Liguori 23 Jul '13

23 Jul '13

We have received numerous requests to extend the CFP deadline and so we are happy to announce that the CFP deadline has been moved by two weeks to August 4th. ================================================================= KVM Forum 2013: Call For Participation October 21-23, 2013 - Edinburgh International Conference Centre - Edinburgh, UK (All submissions must be received before midnight July 21, 2013) ================================================================= KVM is an industry leading open source hypervisor that provides an ideal platform for datacenter virtualization, virtual desktop infrastructure, and cloud computing. Once again, it's time to bring together the community of developers and users that define the KVM ecosystem for our annual technical conference. We will discuss the current state of affairs and plan for the future of KVM, its surrounding infrastructure, and management tools. The oVirt Workshop will run in parallel with the KVM Forum again, bringing in a community focused on enterprise datacenter virtualization management built on KVM. For topics which overlap we will have shared sessions. So mark your calendar and join us in advancing KVM. http://events.linuxfoundation.org/events/kvm-forum/ Once again we are colocated with The Linux Foundation's LinuxCon Europe. KVM Forum attendees will be able to attend oVirt Workshop sessions and are eligible to attend LinuxCon Europe for a discounted rate. http://events.linuxfoundation.org/events/kvm-forum/register We invite you to lead part of the discussion by submitting a speaking proposal for KVM Forum 2013. http://events.linuxfoundation.org/cfp Suggested topics: KVM/Kernel - Scaling and performance - Nested virtualization - I/O improvements - VFIO, device assignment, SR-IOV - Driver domains - Time keeping - Resource management (cpu, memory, i/o) - Memory management (page sharing, swapping, huge pages, etc) - Network virtualization - Security - Architecture ports QEMU - Device model improvements - New devices and chipsets - Scaling and performance - Desktop virtualization - Spice - Increasing robustness and hardening - Security model - Management interfaces - QMP protocol and implementation - Image formats - Firmware (SeaBIOS, OVMF, UEFI, etc) - Live migration - Live snapshots and merging - Fault tolerance, high availability, continuous backup - Real-time guest support Virtio - Speeding up existing devices - Alternatives - Virtio on non-Linux or non-virtualized Management infrastructure - oVirt (shared track w/ oVirt Workshop) - Libvirt - KVM autotest - OpenStack - Network virtualization management - Enterprise storage management Cloud computing - Scalable storage - Virtual networking - Security - Provisioning SUBMISSION REQUIREMENTS Abstracts due: July 21, 2013 Notification: August 1, 2013 Please submit a short abstract (~150 words) describing your presentation proposal. In your submission please note how long your talk will take. Slots vary in length up to 45 minutes. Also include in your proposal the proposal type -- one of: - technical talk - end-user talk - birds of a feather (BOF) session Submit your proposal here: http://events.linuxfoundation.org/cfp You will receive a notification whether or not your presentation proposal was accepted by Aug 1st. END-USER COLLABORATION One of the big challenges as developers is to know what, where and how people actually use our software. We will reserve a few slots for end users talking about their deployment challenges and achievements. If you are using KVM in production you are encouraged submit a speaking proposal. Simply mark it as an end-user collaboration proposal. As an end user, this is a unique opportunity to get your input to developers. BOF SESSION We will reserve some slots in the evening after the main conference tracks, for birds of a feather (BOF) sessions. These sessions will be less formal than presentation tracks and targetted for people who would like to discuss specific issues with other developers and/or users. If you are interested in getting developers and/or uses together to discuss a specific problem, please submit a BOF proposal. HOTEL / TRAVEL The KVM Forum 2013 will be held in Edinburgh, UK at the Edinburgh International Conference Centre. http://events.linuxfoundation.org/events/kvm-forum/hotel Thank you for your interest in KVM. We're looking forward to your submissions and seeing you at the KVM Forum 2013 in October! Thanks, -your KVM Forum 2013 Program Committee Please contact us with any questions or comments.

[libvirt] [PATCH] qemu: Take error path if acquiring of job fails in qemuDomainSaveInternal
by Peter Krempa 23 Jul '13

23 Jul '13

Due to a goto statement missed when refactoring in 2771f8b74c1bf50d1fa when acquiring of a domain job failed the error path was not taken. This resulted into a crash afterwards as a extra reference was removed from a domain object leading to it being freed. An attempt to list the domains afterwards leaded to a crash of the daemon afterwards. https://bugzilla.redhat.com/show_bug.cgi?id=928672 --- Sorry for breaking that in the first place :/ src/qemu/qemu_driver.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 0af76a5..96f87cd 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -2987,8 +2987,8 @@ qemuDomainSaveInternal(virQEMUDriverPtr driver, virDomainPtr dom, if (!qemuMigrationIsAllowed(driver, vm, vm->def, false, false)) goto cleanup; - if (qemuDomainObjBeginAsyncJob(driver, vm, - QEMU_ASYNC_JOB_SAVE) < 0) + if (qemuDomainObjBeginAsyncJob(driver, vm, QEMU_ASYNC_JOB_SAVE) < 0) + goto cleanup; memset(&priv->job.info, 0, sizeof(priv->job.info)); priv->job.info.type = VIR_DOMAIN_JOB_UNBOUNDED; -- 1.8.3.2

[libvirt] [PATCH] Make locking more debuggable from logs
by Martin Kletzander 23 Jul '13

23 Jul '13

With this patch, there is new ./configure option '--enable-lock-debug' which controls whether we want to turn on debugging locks. This feature is exposed as a ./configure option due to its huge overhead in speed/log size and is only meant to be used with this in mind. It is designed in a way that even log from deadlocked daemon should provide enough info to find the deadlock itself. Every matching Lock() call can be matched with its Unlock() call and with every Lock() called it is visible whether it failed or not. Unlock() call follows the same output, even though unnecessary (the call cannot block). Lock logging is disabled while logging because that would either recurse or deadlock.

[libvirt] [PATCH] cpu: Let explicit features override model features
by Jiri Denemark 22 Jul '13

22 Jul '13

Until now CPU features inherited from a specified CPU model could only be overridden with 'disable' policy. With this patch, any explicitly specified feature always overrides the same feature inherited from a CPU model regardless on the specified policy. The CPU in x86-exact-force-Haswell.xml would previously be incompatible with x86-host-SandyBridge.xml CPU even though x86-host-SandyBridge.xml provides all features required by x86-exact-force-Haswell.xml. --- src/cpu/cpu_x86.c | 5 +++++ tests/cputest.c | 1 + tests/cputestdata/x86-exact-force-Haswell.xml | 15 +++++++++++++++ tests/cputestdata/x86-host-SandyBridge.xml | 6 ++++++ 4 files changed, 27 insertions(+) create mode 100644 tests/cputestdata/x86-exact-force-Haswell.xml create mode 100644 tests/cputestdata/x86-host-SandyBridge.xml diff --git a/src/cpu/cpu_x86.c b/src/cpu/cpu_x86.c index 4564bd4..a388f0f 100644 --- a/src/cpu/cpu_x86.c +++ b/src/cpu/cpu_x86.c @@ -1223,6 +1223,11 @@ x86Compute(virCPUDefPtr host, goto out; } + /* first remove features that were inherited from the CPU model and were + * explicitly forced, disabled, or made optional + */ + x86DataSubtract(cpu_require->data, cpu_force->data); + x86DataSubtract(cpu_require->data, cpu_optional->data); x86DataSubtract(cpu_require->data, cpu_disable->data); result = x86ModelCompare(host_model, cpu_require); if (result == SUBSET || result == UNRELATED) { diff --git a/tests/cputest.c b/tests/cputest.c index d3865c4..803e395 100644 --- a/tests/cputest.c +++ b/tests/cputest.c @@ -581,6 +581,7 @@ mymain(void) DO_TEST_COMPARE("x86", "host", "pentium3-amd", VIR_CPU_COMPARE_INCOMPATIBLE); DO_TEST_COMPARE("x86", "host-amd", "pentium3-amd", VIR_CPU_COMPARE_SUPERSET); DO_TEST_COMPARE("x86", "host-worse", "nehalem-force", VIR_CPU_COMPARE_IDENTICAL); + DO_TEST_COMPARE("x86", "host-SandyBridge", "exact-force-Haswell", VIR_CPU_COMPARE_IDENTICAL); /* guest updates for migration * automatically compares host CPU with the result */ diff --git a/tests/cputestdata/x86-exact-force-Haswell.xml b/tests/cputestdata/x86-exact-force-Haswell.xml new file mode 100644 index 0000000..614ed7e --- /dev/null +++ b/tests/cputestdata/x86-exact-force-Haswell.xml @@ -0,0 +1,15 @@ +<cpu mode='custom' match='exact'> + <model fallback='allow'>Haswell</model> + <feature policy='force' name='pcid'/> + <feature policy='force' name='rtm'/> + <feature policy='force' name='invpcid'/> + <feature policy='force' name='erms'/> + <feature policy='force' name='bmi2'/> + <feature policy='optional' name='smep'/> + <feature policy='optional' name='avx2'/> + <feature policy='optional' name='hle'/> + <feature policy='force' name='bmi1'/> + <feature policy='force' name='fsgsbase'/> + <feature policy='disable' name='movbe'/> + <feature policy='disable' name='fma'/> +</cpu> diff --git a/tests/cputestdata/x86-host-SandyBridge.xml b/tests/cputestdata/x86-host-SandyBridge.xml new file mode 100644 index 0000000..7f26b7b --- /dev/null +++ b/tests/cputestdata/x86-host-SandyBridge.xml @@ -0,0 +1,6 @@ +<cpu> + <arch>x86_64</arch> + <model>SandyBridge</model> + <vendor>Intel</vendor> + <topology sockets='1' cores='2' threads='2'/> +</cpu> -- 1.8.3.2

[libvirt] [RFC PATCH] qemu: Shorten SCSI hostdev alias to avoid QEMU failure
by Viktor Mihajlovski 22 Jul '13

22 Jul '13

The alias for hostdevs of type SCSI can be too long for QEMU if larger LUNs are encountered. Here's a real life example: <hostdev mode='subsystem' type='scsi' managed='no'> <source> <adapter name='scsi_host0'/> <address bus='0' target='19' unit='1088634913'/> </source> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </hostdev> this results in a too long drive id, resulting in QEMU yelling Property 'scsi-generic.drive' can't find value 'drive-hostdev-scsi_host0-0-19-1088634913' This commit changes the alias back to the default hostdev$(index) scheme. Signed-off-by: Viktor Mihajlovski <mihajlov(a)linux.vnet.ibm.com> --- Actually this is highlighting a larger issue. Apparently QEMU ids are limited to a length of 32 bytes. This means that SCSI based drives are also in danger to exceed this limit. We should consider to use a drive index for controller-attached disks for alias generation instead of the verbose drive-$bustype-$busaddress schema. src/qemu/qemu_command.c | 10 +--------- .../qemuxml2argv-hostdev-scsi-boot.args | 4 ++-- .../qemuxml2argv-hostdev-scsi-lsi.args | 4 ++-- .../qemuxml2argv-hostdev-scsi-readonly.args | 4 ++-- .../qemuxml2argv-hostdev-scsi-virtio-scsi.args | 4 ++-- 5 files changed, 9 insertions(+), 17 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index 879aed8..8c8bef2 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -818,16 +818,8 @@ qemuAssignDeviceHostdevAlias(virDomainDefPtr def, virDomainHostdevDefPtr hostdev } } - if (hostdev->source.subsys.type == VIR_DOMAIN_HOSTDEV_SUBSYS_TYPE_SCSI) { - if (virAsprintf(&hostdev->info->alias, "hostdev-%s-%d-%d-%d", - hostdev->source.subsys.u.scsi.adapter, - hostdev->source.subsys.u.scsi.bus, - hostdev->source.subsys.u.scsi.target, - hostdev->source.subsys.u.scsi.unit) < 0) - return -1;

[libvirt] [PATCH] Split up platfrom specifics from bridge driver
by Roman Bogorodskiy 22 Jul '13

22 Jul '13

This is a second step for making bridge_driver more portable. This one splits up bridge driver into platform specific and general parts. Platform specifc parts are mostly firewalling stuff. So the support for new platforms should be added by implementing bridge_driver_$platform.c However, you might notice I didn't move some ports of the platform specific code. E.g. I left networkEnableIpForwarding in bridge_driver.c because it feels like the implementation for e.g. all BSDs would be the same (while firewalling stuff would be different on BSDs) to avoid code copy/paste.

[libvirt] [RESEND PATCH 0/5] Handling of undefine and redefine snapshots with VirtualBox 4.2
by Manuel VIVES 22 Jul '13

22 Jul '13

Hi, This is a serie of patches in order to support undefining and redefining snapshots with VirtualBox 4.2. The serie of patches is rather big, and adds among other things some utility functions unrelated to VirtualBox in patches 1 & 2. The code review could be done in several parts: e.g. patches 1 & 2 separately to validate the utility functions. The VirtualBox API provides only high level operations to manipulate snapshots, so it not possible to support flags like VIR_DOMAIN_SNAPSHOT_CREATE_REDEFINE and VIR_DOMAIN_SNAPSHOT_DELETE_METADATA_ONLY with only API calls. Following an IRC talk with Eric Blake, the decision was taken to emulate these behaviours by manipulating directly the .vbox XML files. The first two patches are some util methods for handling uuid and strings that will be used after. The third patch brings more details in the snapshot XML returned by libvirt. We will need those modifications in order to redefine the snapshots. The fourth patch brings the support of the VIR_DOMAIN_SNAPSHOT_CREATE_REDEFINE and VIR_DOMAIN_SNAPSHOT_CREATE_CURRENT flags in virDomainSnapshotCreateXML. The fifth and last patch brings the support of the VIR_DOMAIN_SNAPSHOT_DELETE_METADATA_ONLY flag in virDomainSnapshotDelete. The patches are only for Virtualbox 4.2 Regards, Manuel VIVES Manuel VIVES (5): viruuid.h/c: Util method for finding uuid patterns in some strings virstring.h/c: Util method for making some find and replace in strings vbox_tmpl.c: Better XML description for snapshots vbox_tmpl.c: Patch for redefining snapshots vbox_tmpl.c: Add methods for undefining snapshots src/conf/domain_conf.c | 20 +- src/libvirt_private.syms | 2 + src/util/virstring.c | 129 ++++ src/util/virstring.h | 6 + src/util/viruuid.c | 79 ++ src/util/viruuid.h | 1 + src/vbox/vbox_tmpl.c | 1821 +++++++++++++++++++++++++++++++++++++++++++--- 7 files changed, 1938 insertions(+), 120 deletions(-) -- 1.7.10.4

[libvirt] CfP 8th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '13)
by VHPC 12 20 Jul '13

20 Jul '13

we apologize if you receive multiple copies of this CfP ================================================================= CALL FOR PAPERS 8th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '13) as part of SC 13, Denver, Colorado | sponsored by ACM sighpc ================================================================= Date: November 22, 2013 Workshop URL: http://vhpc.org Paper Submission Deadline: September 23, 2013 CALL FOR PAPERS Virtualization has become a common abstraction layer in modern data centers, enabling resource owners to manage complex infrastructures independently of their applications. Conjointly, virtualization is becoming a driving technology for a manifold of industry grade IT services. The cloud concept includes the notion of a separation between resource owners and users, adding services such as hosted application frameworks and queueing. Utilizing the same infrastructure, clouds carry significant potential for use in cpu-intensive or data-intensive computing. The ability of clouds to provide for requests and releases of vast computing resources dynamically and close to the marginal cost of providing the services is unprecedented in the history of scientific and commercial computing. This workshop aims to bring together industrial providers with the application community in order to foster discussion, collaboration and mutual exchange of knowledge and experience. The workshop will be one day in length, composed of 20 min paper presentations, each followed by 10 min discussion sections. Lightning talks are limited to 5 minutes. Presentations may be accompanied by interactive demonstrations. TOPICS Topics of interest include, but are not limited to: - Management, deployment and monitoring of VM-based environments - VM-cloud performance monitoring - VM cloud topology management and optimization - Operating systems virtualization supportpptimization - VM-based cloud performance modelling - Network virtualization for VM-environments - Data virtualization - Cloudbursting - Evolved grid architectures including such based on network virtualization - Workload characterization for VM-based environments - Optimized communication libraries/protocols in the cloud - System and process/bytecode VM convergence - Cloud frameworks and APIs - GPU Virtualization architectures and APIs - Checkpointing/migration of large compute jobs - Instrumentation interfaces and languages - VMM performance (auto-)tuning on various load types - Cloud reliability, fault-tolerance, and security - Heterogeneous virtualized environments - Paravirtualized I/O - Services in cloud HPC - Research and education use cases - Virtualization in cloud, cluster and grid environments - Cross-layer VM optimizations - Cloud HPC use cases including optimizations - Energy-aware virtualization - Performance and cost modelling - QoS and and service levels - Languages for describing highly-distributed compute jobs - VM cloud and cluster distribution algorithms, load balancing - Instrumentation interfaces and languages - Hypervisor extensions and tools for cluster and grid computing - Virtual machine monitor platforms - Cluster provisioning in the cloud Important Dates: Rolling Paper registration September 23, 2013 - Full paper submission October 21, 2013 - Acceptance notification November 8, 2013 - Camera-ready version due Lightning Talks: August 9, 2013 - Deadline for lightning talk abstracts September 2, 2013 - Lightning talk notification November 22, 2013 - Workshop Date TPC CHAIR Michael Alexander (chair), TU Wien, Austria Gianluigi Zanetti (co-chair), CRS4, Italy Anastassios Nanos (co-chair), NTUA, Greece PROGRAM COMMITTEE Costas Bekas, IBM, Switzerland Jakob Blomer, CERN Giovanni Busonera, CRS4, Italy Roberto Canonico, University of Napoli Federico II, Italy Simon Crosby, Bromium, USA Tommaso Cucinotta, Alcatel-Lucent Bell Labs, Ireland Casimer DeCusatis, IBM, USA William Gardner, University of Guelph, USA Marcus Hardt, Forschungszentrum Karlsruhe, Germany Sverre Jarp, CERN, Switzerland Xuxian Jiang, NC State, USA Krishna Kant, George Mason University, USA Romeo Kinzler, IBM, Switzerland Nectarios Koziris, National Technical University of Athens, Greece Simone Leo, CRS4, Italy Jean-Marc Menaud, Ecole des Mines de Nantes, France Dimitrios Nikolopoulos, Queen's University of Belfast, UK Josh Simons, VMWare, USA Borja Sotomayor, University of Chicago, USA Yoshio Turner, HP Labs, USA Kurt Tutschku, Blekinge Institute of Technology, Sweden 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.
