Understanding the fence_virtd serial listener
by Ian Pilcher 16 Mar '15

16 Mar '15

I'm trying to understand the fence_virt.conf options for the serial listener, specifically the "uri" and "path" options. * uri - Is this option only used when using the vmchannel mode? I can't figure out what it could possibly be doing in serial mode. * path - I *really* can't figure this one out. In fact, I'm completely mystified by how fence_virtd figures out what sockets it should listen to for VM requests. Anyone? -- ======================================================================== Ian Pilcher arequipeno(a)gmail.com -------- "I grew up before Mark Zuckerberg invented friendship" -------- ========================================================================

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.

Re: [fedora-virt] Problem assigning an NVIDIA Quadro K2000 to a guest OS

Can I use an installed version of Windows 7 on a real partition with virt? I wanted to get something fully working so I made a Windows 7 installation on a uefi drive last night. That way i can directly boot into windows or via virt-manager.

This is not the way GPU assignment works. GPU assignment of Quadro cards is very much like assignment of a NIC. When the NIC is assigned to the VM, the network cable attached to the NIC is used by the VM. When a GPU is assigned, the accelerated graphics channel is through the video outputs of the GPU card. Somehow the idea of rendering into a Window on the host is a common misconception. There is some opportunity to due this, but not with Windows 7 as a guest and at a huge cost to performance. You can of course use the input selection button on you monitor to select an input channel connected to the assigned GPU. > Steps done so far: > 1.

Now checking them I see: > $ ls /dev/vfio > 17 vfio It's good that you verified the IOMMU group only contains the GPU itself and audio function, but beyond that, these steps aren't necessary. So long as the hostdev device in your domain XML is set to managed, which is the default when using virt-manager, the binding of the assigned device to vfio is handled by libvirt. However, it's generally recommended to prevent host drivers from binding to the GPU (they're not as well practiced at releasing devices as NIC drivers), so we'll want to configure pci-stub to claim it rather than nouveau. We also need to deal with the audio function since it's part of the IOMMU group, so we'll handle it the same way. To do this, take the PCI vendor and device IDs that you show above and add the following to your kernel commandline: pci-stub.ids=10de:0ffe,10de:0e1b You can do this by editing /etc/sysconfig/grub and re-running grub2-mkconfig and rebooting. After reboot, if you run "lspci -ks 3:", pci-stub should show as the driver in use for both GPU and audio functions. Now, attach a monitor to the Quadro card and you should find that when the Nvidia driver is initialized in the guest, the console window in virt-manager freezes (Windows7 disables that graphics controller) and the monitor initializes. If you were to use Windows 8, the guest would be able to use both the virt-manager window and the physical monitor simultaneously as if it were a dual-monitor setup. In this mode you can even get 3D graphics in the virt-manager window, but *at greatly reduced performance*. Hope that helps, Alex

Problem assigning an NVIDIA Quadro K2000 to a guest OS
by storri 09 Mar '15

09 Mar '15

I followed a presentation (www.linux-kvm.org/wiki/images/b/b4/2012-forum-VFIO.pdf) to try to enable VGA passthrough for the guest OS. This is my first attempt at using QEMU+KVM to install a guest OS. My intention is to have the guest OS have direct access to the GPU for 3d gaming. Problem: Not sure if it is setup right. Launching the VM appears to be ok. I can open windows and such but if I try to change the resolution from 800x600 to something higher I get a lot garbage on the screen. Moving the mouse pointer causes the background image to draw over the task bar. My current setup: GPU1: NVIDIA GeForce 780 Ti (Two monitors currently connected) GPU2: NVIDIA Quadro K2000 (No monitors connected) - NVIDIA 346.47 properitary drivers installed. - Xinerama is disabled due to possible GDM bug. Goal: (Not using VM): Linux desktop stretched across both monitors (Using VM): Guest OS has full screen rendering on one montior while linux is one the other. Steps done so far: 1. Used virt-manager to create a storage device on a SSD (50GB size) 2. Installed Windows 7 in VM 3. Updated Windows 7 4. Enable virtualization support and added PCI 0000:03:00.0 as a physical PCI device to the VM. 5. Thinking I was not done (due to ignorance) I followed the presentation I linked above to find device to assign: $ sudo lspci -nn | grep NVIDIA 02:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK110B [GeForce GTX 780 Ti] [10de:100a] (rev a1) 02:00.1 Audio device [0403]: NVIDIA Corporation GK110 HDMI Audio [10de:0e1a] (rev a1) 03:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK107GL [Quadro K2000] [10de:0ffe] (rev a1) 03:00.1 Audio device [0403]: NVIDIA Corporation GK107 HDMI Audio Controller [10de:0e1b] (rev a1) 6. Worked on finding the group: $ sudo readlink /sys/bus/pci/devices/0000\:03\:00.0/iommu_group ../../../../kernel/iommu_groups/17 7. Now that I have the group I worked to find the devices in the group: $ sudo ls /sys/bus/pci/devices/0000\:03\:00.0/iommu_group/devices 0000:03:00.0 0000:03:00.1 *** Ok. So two devices need to dealt with here. 8. I unbinded each from the device driver $ echo 0000:03:00.0 | sudo tee \ /sys/bus/pci/devices/0000:03:00.0/driver/unbind $ echo 0000:03:00.1 | sudo tee \ /sys/bus/pci/devices/0000:03:00.1/driver/unbind 9. Found the vendor and device ID for each: $ sudo lspci -n -s 03:00.0 03:00.0 0300: 10de:0ffe (rev a1) $ sudo lspci -n -s 03:00.1 03:00.1 0403: 10de:0e1b (rev a1) 10. Now I bind them to vfio-pci $ echo 10de 0ffe | sudo tee \ /sys/bus/pci/drivers/vfio-pci/new_id $ echo 10de 01eb | sudo tee \ /sys/bus/pci/drivers/vfio-pci/new_id ** Not sure about this. I am not sure I have bounded them correctly. 11. Now checking them I see: $ ls /dev/vfio 17 vfio

Re: [fedora-virt] virt Digest, Vol 74, Issue 6

I've had similar problems running Windows 7 as a guest that were solved by installing the Windows guest tools ( http://www.spice-space.org/download.html ) and increasing the screen resolution in the guest. QXL works much better for me in Windows when the resolution is increased to something higher than 1024. Might not apply to you, but that's the only trouble I've seen with it.
