Hello all. I have cluster working in my company The hosts and storage are connect througt iSCIS connection. Everi think is working correctly. Now we need to put another storage. We configured iSCSI in all hosts and I can see when we on the storage managerment, and we want to put this new storage in the pool to make a HA cluter But I'm afread to disturb the function on my running enverioment.

igmp snooping and bridging
by Nicolas Ecarnot 16 Jun '14

16 Jun '14

Hi, I know this may sounds few related to oVirt, but here is what happened here : We have two oVirt datacenters in 3.4.1 (and 3.4 compat. level), and amongst many other things, we have a ctdb cluster composed of two nodes, each of them being in a different datacenter. Some days ago, I raise the compat. level from 3.3 to 3.4, upgraded the hosts of datacenter#1 from centOS 6.4 to 6.5 (datacenter#2 was already 6.5), and our two (VM)ctdb nodes (centOS 6.5) were constantly failing into cluster partition. Almost 3 days of googling lead me to a point that seems know for some times, being : multicast on bridged interfaces is more or less supported, or randomly supported. See : http://lists.corosync.org/pipermail/discuss/2012-November/002208.html On the concerned hosts, I tried the advised workaround, and yes, that stabilized the situation. I understand this is not directly oVirt/RHEV related, but I really don't get why this ctdb cluster has worked for months, and stopped recently (I'll have to deeply dig into the release notes of the upgraded packages and try to find something useful). I post that here to : - ask if some of you are also running clusters amongst VMs (not particularly amongst datacenters - VM discussion amongst hosts may also be an issue) - leave a trace in case that may help debug some setups Regards, -- Nicolas Ecarnot

----- Forwarded Message ----- From: "Paolo Bonzini" <pbonzini(a)redhat.com> To: "Libvirt" <libvir-list(a)redhat.com> Sent: Monday, June 16, 2014 12:08:22 PM Subject: [libvirt] KVM Forum 2014 Call for Participation ================================================================= KVM Forum 2014: Call For Participation October 14-16, 2014 - Congress Centre Düsseldorf - Düsseldorf, Germany (All submissions must be received before midnight July 27, 2014) ================================================================= 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/ Once again we are colocated with the Linux Foundation's LinuxCon Europe, CloudOpen Europe, Embedded Linux Conference (ELC) Europe, and this year, the Linux Plumbers Conference. KVM Forum attendees will be able to attend LinuxCon + CloudOpen + ELC for a discounted rate. http://events.linuxfoundation.org/events/kvm-forum/attend/register We invite you to lead part of the discussion by submitting a speaking proposal for KVM Forum 2014. 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. - Storage: glusterfs, Ceph, etc. - Software defined networking: Open vSwitch, OpenDaylight, etc. - Network Function Virtualization - Security - Provisioning - Performance tuning =============== SUBMITTING YOUR PROPOSAL =============== Abstracts due: July 27, 2014 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 Aug 20th. 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, it should focus on the work that needs to be done or the difficulties that haven't yet been solved. 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. This time can also be used for hands-on hacking sessions if you have concrete code problems to solve. 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_2014_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 =============== The KVM Forum 2014 will be held in Düsseldorf, Germany at Congress Centre Düsseldorf http://events.linuxfoundation.org/events/kvm-forum/attend/hotel-and-travel =============== IMPORTANT DATES =============== Notification: August 20, 2014 Schedule announced: August 29, 2014 Event dates: October 14-16, 2014 Thank you for your interest in KVM.

Big news from the Node crew! BKP ----- Forwarded Message ----- From: "Fabian Deutsch" <fdeutsch(a)redhat.com> To: devel(a)ovirt.org Sent: Monday, June 16, 2014 7:00:26 AM Subject: Say Hello to the oVirt Engine Virtual Appliance Hey, one of the things on the list for oVirt 3.5 was the oVirt Virtual Appliance. Huh, what’s that? You might ask. Well, imagine a cloud image with oVirt Engine 3.5 and it’s dependencies pre-installed, and a sane default answer file for ovirt-engine-setup. All of this delivered in an OVA file. The intention is to get you a running oVirt Engine without much hassle. Furthermore this appliance can be used in conjunction with - and is actually intended for - the Self Hosted Engine feature, and the upcoming oVirt Node Hosted Engine plugin. More informations and links about the appliance and how to build it can be found here: http://dummdida.tumblr.com/post/88944206100/say-hello-to-the-ovirt-engine-v… Testing it with hosted engine is the next step. Greetings fabian

Gluster VMs Paused State then not resumable
by Andrew Lau 14 Jun '14

14 Jun '14

Hi all, I'm wondering if anyone's had any luck with running VMs on top of a gluster VM? I have a bug open here, https://bugzilla.redhat.com/show_bug.cgi?id=1058300 about VMs going into a paused state and not being able to resume. It's gone a little quiet, so I was wondering has anyone else had any luck with this style of setup? I have my gluster and virt on the same boxes, and currently 5 in the cluster (replica 2) A few cases this can be reproduced: - switch dies - cable unplug - gluster volume stop - gluster brick dies I recently tried a suggested volume option: gluster volume set vm-data network.ping-timeout 10 The qemu logs now report on virsh resume vmname: block I/O error in device 'drive-virtio-disk0': Transport endpoint is not connected (107) Thanks, Andrew

Hi all, after today's CentOS "yum update", I had once more the Problem with LIVE Snapshots due to the new "qemu packages". Can anyone explain me why there is such a huge difference between the "CENTOS QEMU Packages" and the "Jenkins RHEV qemu Packages". CENTOS QEMU = LIVE Snapshot failed (tested with qemu versions V8 and V10) * VDSErrorException: VDSGenericException: VDSErrorException: Failed to SnapshotVDS, error = Snapshot failed, code = 48 JENKINS QEMU = LIVE Snapshots ok (tested with qemu versions V8 and V10) * Command CreateAllSnapshotsFromVm, Parameters Type org.ovirt.engine.core.common.asynctasks.AsyncTaskParameters) returned status finished, result 'success'. Thanks! Christian
