by Eric Blake 07 May '12

07 May '12

v5: https://www.redhat.com/archives/libvir-list/2012-April/msg00753.html Differences in v6: - rebased on top of accepted patches v5:1-4/23 and latest tree - corresponds to patches v5:7-14/23 - patch 5/8 is new - patch v5:12/23 is dropped; qemu is giving us something better, but I still need to finish writing that patch - patch v5:11/23 comments were incorporated, with better cleanup on error - tweak series to deal with potential for qemu 1.1 to support copy but not pivot - limit series to just the bare minimum for now; patches from v5:15/23 are still on my tree, but not worth submitting until we know more about what qemu will provide I'm posting this more for reference for my efforts to backport this to RHEL 6 where I have tested against a candidate qemu build, and don't this is ready for upstream until we have confirmation that actual patches have gone into at least the qemu block queue for 1.1.

[libvirt] [PATCHv3 0/4] util: fix libvirtd startup failure due to netlink error
by Laine Stump 07 May '12

07 May '12

The initial patch in this series is the same as the single patch I provided before, but in addition there are 3 new patches that take care of the fallout from 1/4 by: 2/4) removing hard-coding of the src nl_pid when virNetLinkCommand is sending a message 3/4) adding a helper function to retrieve the local nl_pid from a libnl socket and 4/4) using that value when appropriate (I think). As before, I'm unable to fully test this myself, so I won't push unless/until I get verification it works.

[libvirt] Submission Deadline Extension
by VHPC 12 06 May '12

06 May '12

we apologize if you receive multiple copies of this CFP =================================================================== CALL FOR PAPERS 7th Workshop on Virtualization in High-Performance Cloud Computing VHPC '12 as part of Euro-Par 2012, Rhodes Island, Greece =================================================================== Date: August 28, 2012 Workshop URL: http://vhpc.org SUBMISSION DEADLINE: June 11, 2012 - Full paper submission (extended) SCOPE: Virtualization has become a common abstraction layer in modern data centers, enabling resource owners to manage complex infrastructure 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 high-performance scientific 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. Distributed computing concepts that leverage federated resource access are popular within the grid community, but have not seen previously desired deployed levels so far. Also, many of the scientific data centers have not adopted virtualization or cloud concepts yet. This workshop aims to bring together industrial providers with the scientific 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. Presentations may be accompanied by interactive demonstrations. TOPICS Topics of interest include, but are not limited to: Higher-level cloud architectures, focusing on issues such as: - Languages for describing highly-distributed compute jobs - Workload characterization for VM-based environments - Optimized communication libraries/protocols in the cloud - Cross-layer optimization of numeric algorithms on VM infrastructure - System and process/bytecode VM convergence - Cloud frameworks and API sets - Checkpointing/migration of large compute jobs - Instrumentation interfaces and languages - VMM performance (auto-)tuning on various load types - Cloud reliability, fault-tolerance, and security - Software as a Service (SaaS) architectures - Research and education use cases - Virtualization in cloud, cluster and grid environments - Cross-layer VM optimizations - Cloud use cases including optimizations - VM-based cloud performance modelling - Performance and cost modelling Lower-level design challenges for Hypervisors, VM-aware I/O devices, hardware accelerators or filesystems in VM environments, especially: - Cloud, grid and distributed filesystems - Hardware for I/O virtualization (storage/network/accelerators) - Storage and network I/O subsystems in virtualized environments - Novel software approaches to I/O virtualization - Paravirtualized I/O subsystems for modified/unmodified guests - Virtualization-aware cluster interconnects - Direct device assignment - NUMA-aware subsystems in virtualized environments - Hardware Accelerators in virtualization (GPUs/FPGAs) - Hardware extensions for virtualization - VMMs/Hypervisors for embedded systems Data Center management methods, including: - QoS and and service levels - VM cloud and cluster distribution algorithms - VM load-balancing in Clouds - Hypervisor extensions and tools for cluster and grid computing - Fault tolerant VM environments - Virtual machine monitor platforms - Management, deployment and monitoring of VM-based environments - Cluster provisioning in the Cloud PAPER SUBMISSION Papers submitted to the workshop will be reviewed by at least two members of the program committee and external reviewers. Submissions should include abstract, key words, the e-mail address of the corresponding author, and must not exceed 10 pages, including tables and figures at a main font size no smaller than 11 point. Submission of a paper should be regarded as a commitment that, should the paper be accepted, at least one of the authors will register and attend the conference to present the work. Accepted papers will be published in the Springer LNCS series - the format must be according to the Springer LNCS Style. Initial submissions are in PDF; authors of accepted papers will be requested to provide source files. Format Guidelines: http://www.springer.de/comp/lncs/authors.html Style template: ftp://ftp.springer.de/pub/tex/latex/llncs/latex2e/llncs2e.zip Abstract Submission Link: http://edas.info/newPaper.php?c=11943 IMPORTANT DATES Rolling abstract submission June 11, 2012 - Full paper submission (extended) June 29, 2012 - Acceptance notification July 20, 2012 - Camera-ready version due August 28, 2012 - Workshop Date CHAIR Michael Alexander (chair), TU Wien, Austria Gianluigi Zanetti (co-chair), CRS4, Italy Anastassios Nanos (co-chair), NTUA, Greece PROGRAM COMMITTEE Paolo Anedda, CRS4, Italy Giovanni Busonera, CRS4, Italy Brad Calder, Microsoft, USA Roberto Canonico, University of Napoli Federico II, Italy Tommaso Cucinotta, Alcatel-Lucent Bell Labs, Ireland Werner Fischer, Thomas-Krenn AG, Germany William Gardner, University of Guelph, USA Marcus Hardt, Forschungszentrum Karlsruhe, Germany Sverre Jarp, CERN, Switzerland Shantenu Jha, Louisiana State University, USA Xuxian Jiang, NC State, USA Nectarios Koziris, National Technical University of Athens, Greece Simone Leo, CRS4, Italy Ignacio Llorente, Universidad Complutense de Madrid, Spain Naoya Maruyama, Tokyo Institute of Technology, Japan Jean-Marc Menaud, Ecole des Mines de Nantes, France Dimitrios Nikolopoulos, Foundation for Research&Technology Hellas, Greece Jose Renato Santos, HP Labs, USA Walter Schwaiger, TU Wien, Austria Yoshio Turner, HP Labs, USA Kurt Tutschku, University of Vienna, Austria Lizhe Wang, Indiana University, USA Chao-Tung Yang, Tunghai University, Taiwan DURATION: Workshop Duration is one day.

[libvirt] [PATCH] qemu: don't modify domain on failed blockiotune
by Eric Blake 04 May '12

04 May '12

If you have a qemu build that lacks the blockio tune monitor command, then this command: $ virsh blkdeviotune rhel6u2 hda --total_bytes_sec 1000 error: Unable to change block I/O throttle error: internal error Unexpected error fails as expected (well, the error message is lousy), but the next dumpxml shows that the domain was modified anyway. Worse, that means if you save the domain then restore it, the restore will likely fail due to throttling being unsupported, even though no throttling should even be active because the monitor command failed in the first place. * src/qemu/qemu_driver.c (qemuDomainSetBlockIoTune): Check for error before making modification permanent. --- src/qemu/qemu_driver.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index a36c348..2fde15b 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -12011,9 +12011,9 @@ qemuDomainSetBlockIoTune(virDomainPtr dom, qemuDomainObjEnterMonitorWithDriver(driver, vm); ret = qemuMonitorSetBlockIoThrottle(priv->mon, device, &info); qemuDomainObjExitMonitorWithDriver(driver, vm); - vm->def->disks[idx]->blkdeviotune = info; if (ret < 0) goto endjob; + vm->def->disks[idx]->blkdeviotune = info; } if (flags & VIR_DOMAIN_AFFECT_CONFIG) { -- 1.7.7.6

[libvirt] disable usb?
by Gerd Hoffmann 04 May '12

04 May '12

Hi, Is there some way to disable usb altogether? libvirt used to just pass in '-usb'. With the arrival of usb2 support that changed into '-device uhci,...'. Problem is that this breaks with several machine types such as isapc. '-usb' is silently ignored in case the machine type can't handle usb. '-device uhci,...' leads to an error message though and the guest doesn't start. /me tried "<controller type='usb' model='none'/>" which didn't work. Just removing the controller from the xml doesn't work too, it gets automagically readded. Suggestions? thanks, Gerd

[libvirt] [PATCH v3 0/3] usb devices with same vendorID, productID hotplug support
by Guannan Ren 04 May '12

04 May '12

https://bugzilla.redhat.com/show_bug.cgi?id=815755 The set of patch tries to fix the issue when multiple usb devices with same idVendor, idProduct are availible on host, the usb device with lowest bus:device will be attached to guest if usb xml file is given like this: <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x15e1'/> <product id='0x2007'/> </source> </hostdev> The reason is that the usb hotplug function searchs usb device in system files to match vendor and product id, the file with lowest number is always found first. After fix, in this case, libvirt will report an error like: # virsh attach-device rhel6u1 /tmp/usb.xml error: Failed to attach device from /tmp/usb.xml error: operation failed: multiple USB devices for 15e1:2007, use <address> to specify one At the same time, the usb part of domain initilization is also updated in patch 2/3 These patches also fix the problem when using the following xml, the usb device could be hotplugged in two domains without raising errors <hostdev mode='subsystem' type='usb' managed='yes'> <source> <address bus='6' device='7'/> </source> </hostdev> # virsh attach-device rhel6u12nd /tmp/usb_by_bus.xml error: Failed to attach device from /tmp/usb_by_bus.xml error: Requested operation is not valid: USB device 006:007 is in use by domain rhel6u1

[libvirt] [PATCH 2/2] Modify interface qemuDefaultScsiControllerModel().
by Li Zhang 04 May '12

04 May '12

Now, the libvirt sets the default module as 'ibmvscsi' for pseries, and 'lsi' for other platforms.The controller model should be set according to controller type, not only just the platform, otherwise, it will have to set controller's model externally to select right model for specific controller type. This patch is to modify the qemuDefaultScsiControllerModel() interface to set right controller model according to the controller's type. For pseries guest, PCI scsi controller is also supported. So the default scsi controller model is set according to the contrller type. If it is PCI scsi controller, the default model is set as lsi, and if it is VSCSI controller, the default model is set as ibmvscsi.

[libvirt] [PATCH 1/1] Support libnl-3 as well as libnl-1
by Serge Hallyn 03 May '12

03 May '12

configure.ac: Check for libnl-3. If found, find libnl-route-3. If not found, do the original check to look for libnl-1. src/util/virnetlink.c: support libnl3 api. I could play games to make the patch smaller, but this would just hide what is actually needing to be done at the expense of clarity. src/Makefile.am and daemon/Makefile.am: Add LIBNL_ROUTE3_{LIBS,CFLAGS} Unfortunately libnl3 moves netlink/msg.h to /usr/include/libnl3/netlink/msg.h, which is the reason why the LIBNL_CFLAGS need to be added to a bunch of places where they weren't needed with libnl1. Those spots probaby don't actually need to also have LIBNL*LIBS added, but while I may be looking at it wrong, it seemed right to do so. I haven't gotten as far as to compile this into a package on ubuntu, but the source does build with libnl-3 as well as with libnl-1.
