CfP Virtualization in High-Performance Cloud Computing Workshop (VHPC '15)
by VHPC 15 24 Apr '15

24 Apr '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. Docker et al. OS-level virtualization, with its capability to isolate multiple user-space environments allows for their co-existence within the same OS kernel. It promises to provide many of the advantages of machine virtualization with high levels of responsiveness and performance; coupled with lightweight OSs it forms a potent architecture with promise to become a mainstream environment for HPC workloads. 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; 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. 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 - OS-level virtualization including container runtimes (Docker, rkt et al.) - Lightweight compute node operating systems/VMMs - Optimizations of virtual machine monitor platforms, hypervisors and - 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, 2015 - Acceptance notification October 2, 2015 - Camera-ready version due August 25, 2015 - 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 William Magato, University of Cincinnati, USA 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.

Fedora 22 Virt Test Day is Thu Apr 16!
by Cole Robinson 16 Apr '15

16 Apr '15

Hey all, A reminder that the Fedora 22 Virt Test Day is this coming Thu Apr 16. Check out the test day landing page: https://fedoraproject.org/wiki/Test_Day:2015-04-16_Virtualization It's a great time to make sure your virt workflow is still working correctly with the latest packages in Fedora 22. No requirement to run through test cases on the wiki, just show up and let us know what works (or breaks). Updating to a development release of Fedora scares some people, but it's NOT required to help out with the test day: you can test the latest virt bits on the latest Fedora release courtesy of the virt-preview repo. For more details, as well as easy instructions on updating to Fedora 22, see: https://fedoraproject.org/wiki/Test_Day:2015-04-16_Virtualization#What.27s_… Though running latest Fedora 22 on a physical machine is still preferred :) If you want to help out, pop into #fedora-test-day on Thursday and give us a shout! Thanks, Cole

fresh F21 not playing well with firewalld and br0
by Daniel Sanabria 15 Apr '15

15 Apr '15

Hi, I've read so much stuff about this on the web that I'm a bit confused now so wanted to ask here hoping to get some advice. I have a F21 host with br0 configured with a network-script file to obtain its IP via dhcp (no problems with this), firewalld is running on the host and the guests are using br0 and dhcp to obtain the IPs from the same source the host/br0 is getting its own IP. The problem I'm having is that, after some time, packets from the guests are not being forwarded by br0 but I can't quite locate the reason for this. Why br0 stops forwarding packets? What would be the right approach to get this setup working? Thanks in advance, Daniel

Hardware acceleration in my Win7 virtual machine
by David C. Mores 30 Mar '15

30 Mar '15

Use of some applications (e.g. Solitaire) in my Win7 [qemu] virtual machine start with a warning that "Hardware acceleration is either disabled or not supported by your video card driver ...". I understand that the qemu virtual VGA driver is simple. However, is there any activity going on to make a VGA driver that has virtualized access to video hardware acceleration in the host system? Is it available? I'm running Fedora 21 with qemu 2.1.3-3 Dave

I/O errors in guest when cache=none, qcow2 on Btrfs
by Chris Murphy 27 Mar '15

27 Mar '15

Could someone check out this bug, and see if it needs upstream attention? It's currently set to kernel; but I have no idea if it would be libvirt or qemu upstreams to make aware of this. The gist is that on Fedora 21 and 22, when virtio blkc + cache=none + qcow2 on Btrfs, the guest OS (regardless of the file system it uses) starts to experience many I/O errors. If the qcow2 is on XFS, or if cache=writeback or writethrough, the problem doesn't happen. Regression testing shows the problem does not happen on Fedora 20's versions of libvirt and qemu, even with newer kernels. So maybe it's not a kernel problem, or maybe it's a collision of kernel and libvirt or qemu problem, hence the inquiry. Upstream Btrfs is aware of this bug and are looking into it. The fallout of the bug is that gnome-boxes experiences problems since they're currently using cache=none by default (and there's no way to change this in the GUI) when qcow2 is on Btrfs. blk_update_request: I/O error, dev vda, sector XXXXXXXX when qcow2 is on Btrfs https://bugzilla.redhat.com/show_bug.cgi?id=1204569 -- Chris Murphy
