adding new paths to iscsi data storage domains
by Paul Dyer 16 Mar '15

16 Mar '15

Hi, I have been reading the devel list for months now, and would like to ask a question. In version 3.4.5, adding new paths to an existing iSCSI data storage domain does not work from the manager. I have been able to add the paths with command line "iscsiadm -m discovery -t st" and "iscsiadm -m node -L all". Is there any plan to allow for adding new storage paths after the data domain has been created? Thanks, Paul -- Paul Dyer, Mercury Consulting Group, RHCE 504-302-8750

oVirt node, hosted-engine, oVirt appliance and cloud-init
by Simone Tiraboschi 16 Mar '15

16 Mar '15

Hi all, cloud-init is a powerful tool to configure from outside a cloud instance or an appliance as in our scenario. Deploying the engine as an appliance is indeed a good way to speed up and make easier the hosted-engine deployment: you don't need to install an OS on the engine virtual machine and than install the engine and so on but you could simply run a ready to use oVirt engine appliance. But you still need to configure it and so cloud-init support within hosted-engine is a reasonable way to complement it. Then we could also integrate it with oVirt node to let the user input the required info from node TUI in order to have an almost unattended hosted-engine setup on oVirt node using an engine appliance with cloud-init. The idea is to collect the required information interactively from hosted-engine setup or from node TUI (passing them to hosted-engine setup via an answer file) and pass them to the appliance via cloud-init using a no-cloud datasource. So now the question is what do you really want to configure via cloud-init? It's just to define what we want in order to be more focused on user needs: for instance we could configure engine VM instance hostname, we could set the root password, we could create other users, we could upload ssh private keys, we could run a command on the first boot and so on. So, if you have any ideas or requirement about that it's the right time for it. thanks, Simone

KVM Forum 2015/oVirt Workshop: Call For Participation
by Brian Proffitt 11 Mar '15

11 Mar '15

================================================================= KVM Forum 2015: Call For Participation oVirt Workshop: Call For Participation August 19-21, 2015 - Sheraton Seattle - Seattle, WA (All submissions must be received before midnight May 1, 2015) ================================================================= KVM is an industry leading open source hypervisor that provides an ideal platform for datacenter virtualization, virtual desktop infrastructure, and cloud computing. Once again, it's time to bring together the community of developers and users that define the KVM ecosystem for our annual technical conference. We will discuss the current state of affairs and plan for the future of KVM, its surrounding infrastructure, and management tools. Mark your calendar and join us in advancing KVM. http://events.linuxfoundation.org/events/kvm-forum/ This year, the KVM Forum is moving back to North America. We will be colocated with the Linux Foundation's LinuxCon North America, CloudOpen North America, ContainerCon and Linux Plumbers Conference events. Attendees of KVM Forum will also be able to attend a shared hackathon event with Xen Project Developer Summit on August 18, 2015. One track of the KVM Forum will be devoted entirely to a new oVirt Workshop, so those of you with interest in speaking on specifically that subject are invited to submit a proposal as well. We invite you to lead part of the discussion by submitting a speaking proposal for KVM Forum 2015. http://events.linuxfoundation.org/cfp Suggested topics: KVM/Kernel * Scaling and optimizations * Nested virtualization * Linux kernel performance improvements * Resource management (CPU, I/O, memory) * Hardening and security * VFIO: SR-IOV, GPU, platform device assignment * Architecture ports QEMU * Management interfaces: QOM and QMP * New devices, new boards, new architectures * Scaling and optimizations * Desktop virtualization and SPICE * Virtual GPU * virtio and vhost, including non-Linux or non-virtualized uses * Hardening and security * New storage features * Live migration and fault tolerance * High availability and continuous backup * Real-time guest support * Emulation and TCG * Firmware: ACPI, UEFI, coreboot, u-Boot, etc. * Testing Management and infrastructure * Managing KVM: Libvirt, OpenStack, oVirt, etc. * oVirt-specific topics for oVirt Workshop * Storage: glusterfs, Ceph, etc. * Software defined networking: Open vSwitch, OpenDaylight, etc. * Network Function Virtualization * Security * Provisioning * Performance tuning =============== SUBMITTING YOUR PROPOSAL =============== Abstracts due: May 1, 2015 Please submit a short abstract (~150 words) describing your presentation proposal. Slots vary in length up to 45 minutes. Also include in your proposal the proposal type -- one of: - technical talk - end-user talk Submit your proposal here: http://events.linuxfoundation.org/cfp Please only use the categories "presentation" and "panel discussion" You will receive a notification whether or not your presentation proposal was accepted by May 29, 2015. Speakers will receive a complimentary pass for the event. In the instance that your submission has multiple presenters, only the primary speaker for a proposal will receive a complementary event pass. For panel discussions, all panelists will receive a complimentary event pass. TECHNICAL TALKS A good technical talk should not just report on what has happened over the last year; it should present a concrete problem and how it impacts the user and/or developer community. Whenever applicable, focus on work that needs to be done, difficulties that haven't yet been solved, and on decisions that other developers should be aware of. Summarizing recent developments is okay but it should not be more than a small portion of the overall talk. END-USER TALKS One of the big challenges as developers is to know what, where and how people actually use our software. We will reserve a few slots for end users talking about their deployment challenges and achievements. If you are using KVM in production you are encouraged submit a speaking proposal. Simply mark it as an end-user talk. As an end user, this is a unique opportunity to get your input to developers. HANDS-ON / BOF SESSIONS We will reserve some time for people to get together and discuss strategic decisions as well as other topics that are best solved within smaller groups. These sessions will be announced during the event. If you are interested in organizing such a session, please add it to the list at http://www.linux-kvm.org/page/KVM_Forum_2015_BOF Let people you think might be interested know about it, and encourage them to add their names to the wiki page as well. Please try to add your ideas to the list before KVM Forum starts. PANEL DISCUSSIONS If you are proposing a panel discussion, please make sure that you list all of your potential panelists in your abstract. We will request full biographies if a panel is accepted. =============== HOTEL / TRAVEL =============== KVM Forum 2015 will be taking place at the Sheraton Seattle Hotel. We are pleased to offer attendees a discounted room rate of US$199/night (plus applicable taxes) which includes wifi in your guest room. http://events.linuxfoundation.org/events/kvm-forum/attend/hotel-and-travel includes further information on the Sheraton Seattle and the discounted room rate, as well as on transportation and parking options for the hotel. =============== IMPORTANT DATES =============== Notification: May 29, 2015 Schedule announced: June 3, 2015 Event dates: August 19-21, 2015 Thank you for your interest in KVM. We're looking forward to your submissions and seeing you at the KVM Forum 2015 in August! -your KVM Forum 2015 Program Committee Please contact us with any questions or comments. -- Brian Proffitt Community Liaison oVirt Open Source and Standards, Red Hat - http://community.redhat.com Phone: +1 574 383 9BKP IRC: bkp @ OFTC

[VDSM] bulk stats / sampling overhaul notes
by Francesco Romani 11 Mar '15

11 Mar '15

Hi, For 3.6.0, I'm working on improvements for the sampling/monitoring code in VDSM The sampling/monitoring code is that part of VDSM which periodically checks the state of the VMs (and host also, but that part is out of scope for now), and collect data to be reported to Engine. The point here is "just" to minimize resource consumption and improve scalability, so it can be probabily bluntly summarized as "refactoring" Despite being utterly boring and not-sexy, this change has a quite relevant impact on the VDSM behaviour and architecture. I've collected a summary and some notes here: https://gist.github.com/mojaves/3a917f53cb3151be09da Please bear in mind that the notes are - very terse (and) - very developer-oriented (and) - probably not trivial to grok if one's not following the discussion since the beginning (thus) - these notes are *meant* to spark discussion and bring more interest on the topic So everyone's welcome to contribute! -- Francesco Romani RedHat Engineering Virtualization R & D Phone: 8261328 IRC: fromani

Important changes in the Search Engine code
by Eli Mesika 11 Mar '15

11 Mar '15

Hi All We had in the past many cases in which the search engine returned duplicate records. Most of those cases are not simple to resolve in the DB layer by changing the query due to schema limitations. We had decided to handle that by adding DISTINCT to the queries that the search engine generates [1] However, we might have cases in which both DISTINCT and ORDER BY f({args}) (where f is a function call) is used In that case, we will get SQL exception since the ORDER BY is applied on the DISTINCT result that does not include f as a field. I had prevented using DISTINCT in such cases [2] That means that you still may got duplicates in such cases and then you should handle it in the same method as in [3] (basically returning the function result in the select as a computed field) [1] https://gerrit.ovirt.org/#/c/31896 [2] https://gerrit.ovirt.org/#/c/38459 [3] https://gerrit.ovirt.org/#/c/36946 Thanks Eli Mesika
