Loading the KVM module (Fedora 19 on ppc64, POWER7)
by Andrej Podzimek 30 Sep '13

30 Sep '13

Hello, I'm trying to run libvirtd and KVM on a POWER7 machine. For some reason, virt-manager on a client says there is no KVM support. :-( The KVM module installed on the system cannot be loaded: # modprobe kvm modprobe: ERROR: could not insert 'kvm': Input/output error There are no new messages in dmesg. Presumably, the file /lib/modules/3.10.11-200.fc19.ppc64p7/kernel/arch/powerpc/kvm/kvm.ko is readable; at least sha1sum can read it. This is how the error appears in strace (from open()ing the module to an unsuccessful kcmp()): open("/lib/modules/3.10.11-200.fc19.ppc64p7/kernel/arch/powerpc/kvm/kvm.ko", O_RDONLY|O_CLOEXEC) = 3 read(3, "\177ELF\2\2", 6) = 6 lseek(3, 0, SEEK_SET) = 0 fstat(3, {st_mode=S_IFREG|0744, st_size=273976, ...}) = 0 mmap(NULL, 273976, PROT_READ, MAP_PRIVATE, 3, 0) = 0x1fffffad0000 kcmp(0x3, 0x1ffffff68330, 0, 0x3, 0) = -1 EIO (Input/output error) The OS is a fresh Fedora 19 installation with kernel.ppc64p7 3.10.11-200.fc19. Perhaps this could be a known issue or a glitch related to SELinux, but I have no idea what to try next. Could someone give me a hint, please? Cheers! Andrej

Virtio-SCSI & Windows XP

Hi, Do "Windows XP" guests work with the new virtio-scsi? Do we use the same old virtio drivers during installation? Thanks, Jorge

Specify disk-image format on Virt-Manager
by Jorge Fábregas 27 Sep '13

27 Sep '13

Hi, Are there plans to enhance virt-manager so that it allows you to specify the disk format during the VM-creation wizard? I create a lot VMs with virt-install (where I can specify it) but I also use virt-manger once in a while and would be great if we could specify it there (without first creating the disk image beforehand). I saw an enhancement-request but it was closed as it was for RHEL5. Thanks, Jorge

WinXP & Slow Network Startup (BallonService)
by Jorge Fábregas 27 Sep '13

27 Sep '13

Hi everyone, I'm running Fedora 19 (with Preview Repo) and just installed Windows XP (media already had SP3) and applied all 100+ updates (no additional 3rd party software installed) with VirtIO (on Net & SCSI controller). I'm running the latest virtio drivers. I proceeded to install the SPICE Agent Tools and rebooted the VM and now I can copy/paste from guest to host (very cool). However, I noticed that the network takes about 1.5 minutes to start. I have the "show icon when connected option" and literally takes 1.5 minutes. I searched the mailing list's archive and there was a similar post but apparently the situation there was related to the .NET framework (which I don't have installed). After some trial & error I finally pinpointed the problem to the "BallonService" installed by the SPICE tools. If I set the service to "disabled" and reboot the VM the network starts right away. Has anyone bumped into this? Regards, Jorge

[deadline in 1 week] 8th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '13)
by VHPC 15 17 Sep '13

17 Sep '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) held in conjunction with SC 13, Denver, Colorado | in cooperation with ACM SIGHPC ================================================================= Date: November 22, 2013 Workshop URL: http://vhpc.org Paper Submission Deadline: September 23, 2013 (firm) Invited Talks: - John Goodacre, Director, Technology and Systems, ARM Processor Division The Evolution of the ARM Architecture Towards Big Data and the Data-Centre. - Jacob Bower, VP of Application Engineering, Maxeler Technologies Ltd. Maximizing Performance with cloud-virtualized Dataflow Engine oo-processors. 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 high-throughput 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 - Language-process virtual machines - VM-cloud performance monitoring - VM cloud topology management and optimization - VMs for high-throughput large data analytical workloads - Operating systems virtualization support optimization - 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 (firm) October 9, 2013 - Acceptance notification October 21, 2013 - Camera-ready version due 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 Michael Day, IBM, USA 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.

Virtualization Package Groups
by Jorge Fábregas 14 Sep '13

14 Sep '13

Hi, What happened to the yum package groups: "Virtualization Platform", "Virtualization Client", "Virtualization Tools" etc...? They seemed to be a nice way of grouping the packages. All I see now in Fedora 19 is the plain "Virtualization" group. (I'm moving away from Fedora 14). Thanks, Jorge

Sanlock + libvirt
by Ján ONDREJ (SAL) 12 Sep '13

12 Sep '13

Hello, in sanlock docs (https://fedorahosted.org/sanlock/) there is described, how to use it. There is no mention about NFS. Can I use sanlock with LVM (without NFS) with livbirt? It this feature implemented in libvirt for Fedora or RHEL? For libvirt I need to define lease dir as: disk_lease_dir = "/var/lib/libvirt/sanlock" but this have to be a directory. How to configure it to use sanlock on LVM? SAL
