[libvirt] failed to connect to the hypervisor
by Ameya Pandit 31 Mar '10

31 Mar '10

Hi, I have KVM qemu installed on Fedora 12 host server. My VMs are marked to autostart. When I reboot my host server the virtual machines starts but halts on its bios display screen. If I login mannually destroy the VMs and start again, it just works without any errors. Can someone please help me with this issue ? error logs I found are this : Starting libvirtd daemon: [ OK ] error: unable to connect to '/var/run/libvirt/libvirt-sock': No such file or directory error: failed to connect to the hypervisor some more info : virsh capabilities <capabilities> <host> <cpu> <arch>i686</arch> </cpu> <migration_features> <live/> <uri_transports> <uri_transport>tcp</uri_transport> </uri_transports> </migration_features> </host> <guest> <os_type>hvm</os_type> <arch name='i686'> <wordsize>32</wordsize> <emulator>/usr/bin/qemu</emulator> <machine>pc-0.11</machine> <machine canonical='pc-0.11'>pc</machine> <machine>pc-0.10</machine> <machine>isapc</machine> <domain type='qemu'> </domain> <domain type='kvm'> <emulator>/usr/bin/qemu-kvm</emulator> <machine>pc-0.11</machine> <machine canonical='pc-0.11'>pc</machine> <machine>pc-0.10</machine> <machine>isapc</machine> </domain> </arch> <features> <pae/> <nonpae/> <acpi default='on' toggle='yes'/> <apic default='on' toggle='no'/> </features> </guest> <guest> <os_type>hvm</os_type> <arch name='x86_64'> <wordsize>64</wordsize> <emulator>/usr/bin/qemu-system-x86_64</emulator> <machine>pc-0.11</machine> <machine canonical='pc-0.11'>pc</machine> <machine>pc-0.10</machine> <machine>isapc</machine> <domain type='qemu'> </domain> </arch> <features> <acpi default='on' toggle='yes'/> <apic default='on' toggle='no'/> </features> </guest> </capabilities> Kindly let me know if any more information required inorder to fix this issue. -- Regards, Ameya Pandit Buzz: 90040 27390 | www.ameyapandit.com

[libvirt] [PATCH] nwfilter: fix some make dist/built/rpm issues
by Daniel Veillard 31 Mar '10

31 Mar '10

Here is a couple of patches related to make dist, then build from resulting tarball and rpm building. The first one adds a few missing header files in the associated file variables, it's needed otherwise the missing headers would break compilation from a distribution tarball The second one handles the xml filter files, first they need to be added to EXTRA_DIST from their Makefile.am otherwise they are missing from the tarball, and second that set of file in /etc/ need to be listed in the rpm spec file, associated with the main libvirt rpm (i.e. where the daemon resides as it's useless with just the client). I think those are fairly uncontroversial and are needed to not break the distribution, but I will probably commit those tomorrow, in case someone points out something stupid :-) Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] CfP with Extended Deadline 5th Workshop on Virtualization in High-Performance Cloud Computing (VHPC'10)
by Michael Alexander 30 Mar '10

30 Mar '10

Apologies if you received multiple copies of this message. ================================================================= CALL FOR PAPERS 5th Workshop on Virtualization in High-Performance Cloud Computing VHPC'10 as part of Euro-Par 2010, Island of Ischia-Naples, Italy ================================================================= Date: August 31, 2010 Euro-Par 2009: http://www.europar2010.org/ Workshop URL: http://vhpc.org SUBMISSION DEADLINE: Abstracts: April 4, 2010 (extended) Full Paper: June 19, 2010 (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. Piloted by the Amazon Elastic Computing Cloud services, the cloud concept includes the notion of a separation between resource owners and users, adding services such as hosted application frameworks and queuing. 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 resource 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 datacenters 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. It concludes with a 30 min panel discussion by presenters. TOPICS Topics include, but are not limited to, the following subjects: - Virtualization in cloud, cluster and grid HPC environments - VM cloud, cluster load distribution algorithms - Cloud, cluster and grid filesystems - QoS and and service level guarantees - Cloud programming models, APIs and databases - Software as a service (SaaS) - Cloud provisioning - Virtualized I/O - VMMs and storage virtualization - MPI, PVM on virtual machines - High-performance network virtualization - High-speed interconnects - Hypervisor extensions - Tools for cluster and grid computing - Xen/other VMM cloud/cluster/grid tools - Raw device access from VMs - Cloud reliability, fault-tolerance, and security - Cloud load balancing - VMs - power efficiency - Network architectures for VM-based environments - VMMs/Hypervisors - Hardware support for virtualization - Fault tolerant VM environments - Workload characterizations for VM-based environments - Bottleneck management - Metering - VM-based cloud performance modeling - Cloud security, access control and data integrity - Performance management and tuning hosts and guest VMs - VMM performance tuning on various load types - Research and education use cases - Cloud use cases - Management of VM environments and clouds - Deployment of VM-based environments 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, accepted papers will be requested to provided source files. Format Guidelines: http://www.springer.de/comp/lncs/authors.html Submission Link: http://edas.info/newPaper.php?c=8553 IMPORTANT DATES April 4 - Abstract submission due (extended) May 19 - Full paper submission (extended) July 14 - Acceptance notification August 3 - Camera-ready version due August 31 - September 3 - conference CHAIR Michael Alexander (chair), scaledinfra technologies GmbH, Austria Gianluigi Zanetti (co-chair), CRS4, Italy PROGRAM COMMITTEE Padmashree Apparao, Intel Corp., USA Volker Buege, University of Karlsruhe, Germany Roberto Canonico, University of Napoli Federico II, Italy Tommaso Cucinotta, Scuola Superiore Sant'Anna, Italy Werner Fischer, Thomas Krenn AG, Germany William Gardner, University of Guelph, Canada Wolfgang Gentzsch, DEISA.

[libvirt] ESX snapshot deletion
by Chris Lalancette 30 Mar '10

30 Mar '10

Hey Mattias, I'm currently working on the semantics of virDomainSnapshotDelete(), which has been renamed from the earlier virDomainSnapshotDeactivate(). In qemu/kvm, it seems like it is possible to delete a snapshot at any time, even while that snapshot is running (though I'm not yet sure exactly what happens in that case). Talking to Jirka, it seems like the virtualbox GUI doesn't allow you to do any operations at all on snapshots while a domain is running, although we don't know yet if this is a restriction in the API as well. My questions for you are about how ESX handles this situation: 1) Can you manipulate a domain's snapshots while that domain is running? 2) If so, can you delete the snapshot that is currently running? If so, what happens? -- Chris Lalancette
