[Users] Features/Vdsm for PPC64
by Andrei Vakhnin 18 Sep '12

18 Sep '12

Looks like ovirt-engine and vdsm support for IBM POWER 7 is on road map. Is there a plan to support IBM POWER6 architecture? We're looking to virtualize 5 x IBM POWER6 BladeCenter H to utilize libvirt and KVM on SLES11 pcc64 blades. Thanks http://wiki.ovirt.org/wiki/Features/Vdsm_for_PPC64 Andrei

[Users] Define vlan (pvid and/or trunk) per vNic ? - openvswitch integration
by Benoit ML 14 Sep '12

14 Sep '12

Hello, I'm writing to the ml to know something about ovirt : Is there any possibilité to define a vlan per vNic (pvid and/or trunk) , for each vnic of VM ? I'm working with openvswitch and i can define this. Well, for us, it's the absolute needed (and killing) feature to define well known n-tiers architecture in a virtual world (web fronted, BDD, load-balancer and so on). I'm interesting by oVirt because it seems to be an integrated web interface. Thank you in advance ! Regards, -- -- Benoit

[Users] Speakers Needed: Upcoming Workshops
by Leslie Hawthorn 14 Sep '12

14 Sep '12

Hello everyone, First of all, congratulations to the team on today's release of oVirt 3.1! As mentioned in today's weekly status IRC meeting, we would like to ensure we have broad community participation in upcoming workshops. [0] For KVM Forum + oVirt in Barcelona [1], a general call for papers will be issued within the next few days. I will send a note to these lists when details of the CFP have been announced. For the oVirt workshop to be hosted at Red Hat's Bangalore campus on 16 October 2012, it would be wonderful if folks would propose sessions for this workshop. (We have chosen not to go through a formal CFP process for Bangalore so as to leave sufficient time for the KVM Forum + oVirt CFP process to run most smoothly.) If you would like to propose a session for oVirt Bangalore, please email me and I follow up with you. As usual, any questions, please let me know.

Providing a feature-rich server virtualization management system with advanced capabilities for hosts and guests, including high availability, live migration, storage management, system scheduler, and more. By open we mean open source & open governance, done right. During this workshop you’ll learn about the technical background and direction of the oVirt project. You’ll meet the developers, and have an opportunity to see and dive into the code right away. The workshop is open to all who want to use, get involved with, or learn about the comprehensive open virtualization management platform, oVirt. The sessions cover the technical projects details, governance, getting involved, usage, and much more. If you have any interest in an Open Virtualization Management platform, this workshop is for you! We are excited to announce that this oVirt Workshop will be held in conjunction with the KVM Forum. http://events.linuxfoundation.org/events/kvm-forum/ The KVM Forum and oVirt Workshop are co-located with the Linux Foundation's 2012 LinuxCon Europe in Barcelona, Spain. oVirt Workshop attendees will be able to attend KVM Forum sessions and are eligible to attend LinuxCon Europe for a discounted rate. http://events.linuxfoundation.org/events/kvm-forum/register We invite you to lead part of the discussion by submitting a speaking proposal for oVirt Workshop 2012. http://events.linuxfoundation.org/cfp Suggested topics: - community use case/stories - roadmaps - deep dives into features/areas - deep dives into code/debugging/tuning - integration and extensions - components: engine, vdsm, node, sdk/cli, reports, mom, guest agent, etc. - subjects: network, storage, vm life cycle, scheduling & sla, gluster, etc. - packaging, installation and distributions - community infrastructure and services SUBMISSION REQUIREMENTS Abstracts due: Sep 14th, 2012 Notification: Sep 28th, 2012 Please submit a short abstract (~150 words) describing your presentation proposal. In your submission please note how long your talk will take. Slots vary in length up to 45 minutes. Also include in your proposal the proposal type -- one of: - technical talk - end-user talk - birds of a feather (BOF) session Submit your proposal here: http://events.linuxfoundation.org/cfp You will receive a notification whether or not your presentation proposal was accepted by Sep 14th. END-USER COLLABORATION 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 oVirt in production you are encouraged submit a speaking proposal. Simply mark it as an end-user collaboration proposal. As an end user, this is a unique opportunity to get your input to developers. BOF SESSION We will reserve some slots in the evening after the main conference tracks, for birds of a feather (BOF) sessions. These sessions will be less formal than presentation tracks and targetted for people who would like to discuss specific issues with other developers and/or users. If you are interested in getting developers and/or uses together to discuss a specific problem, please submit a BOF proposal. LIGHTNING TALKS In addition to submitted talks we will also have some room for lightning talks. These are short (5 minute) discussions to highlight new work or ideas that aren't complete enough to warrant a full presentation slot. Lightning talk submissions and scheduling will be handled on-site at oVirt Workshop. HOTEL / TRAVEL The oVirt Workshop Europe 2012 will be held in Barcelona, Spain at the Hotel Fira Palace. http://events.linuxfoundation.org/events/kvm-forum/hotel Thank you for your interest in oVirt.

[Users] Can oVirt be installed in a virtual machine?
by Nicolas Chenier 12 Sep '12

12 Sep '12

Hi all, I am starting a small hosting business and want to use oVirt w/ KVM as my virtualization platform. I currently have 2 host servers and an iSCSI NAS. Do I need a dedicated machine to run oVirt? Can I run it from a VM? Can I use the all-in-one solution in a Production environment, with a 2nd host? ... would I need to install oVirt on both hosts, in the event that one of my servers went down? I am trying to see how I can survive if my oVirt server fails. It would be great if it ran from a VM but I can also see issues with doing that... Another option would be to run oVirt on my workstation and have it connect to my 2 host servers in colocation over the internet? Please let me know how you've accomplished an oVirt setup with 2 servers. Thank you! Nic

[Users] impossible to use multiple vlans on a single nic that already contains ovirtmgmt network as a vlan
by Nathanaël Blanchet 12 Sep '12

12 Sep '12

Here is what's happening : In 3.0, I was used to use one nic for transporting all my vlan network, and ovirtmgmt was part of these vlans. in 3.1/vdsm 4.10, I systematically get a ovirt engine error when attempting to drag a new vlan network to the same nic : *"Error while executing action Setup Networks: Internal oVirt Engine Error"* When looking at the host vdsm log I find this : *"Setup attached more than one network to nic em1, some of which aren't vlans"* So it tells me that the ovirtmgmt bridge is not a vlan and it can add an second vlan network to this card because of this. But this is an error. ovirtmgmt is a vlan network I created by myself : # vi ifcfg-ovirtmgmt NM_CONTROLLED="yes" HWADDR="44:1E:A1:3D:35:92" BOOTPROTO="static" IPADDR=10.34.30.155 PREFIX=24 DNS1=193.52.69.50 GATEWAY=10.34.30.2 DEVICE="ovirtmgmt" ONBOOT="yes" TYPE=Bridge [root@khamsin ovirt-engine]# brctl show bridge name bridge id STP enabled interfaces ovirtmgmt 8000.441ea13d3592 no em1.30 virbr0 8000.000000000000 yes the dialog box in the DC tells it is a vlan 0, so there is a bug here, and plus this network management is not editable to change this. at contrary, we see that the ovirtmgmt is correctlly shown as a vlan in the host network interfaces : em1.30 (10.34.30.155) ovirtmgmt What can I do to use multiple vlan on a single nic? -- Nathanaël Blanchet Supervision réseau Pôle exploitation et maintenance Département des systèmes d'information 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr --------------020304050704020001020101 Content-Type: multipart/related; boundary="------------020507040205040002030102" --------------020507040205040002030102 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit <html> <head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> </head> <body bgcolor="#FFFFFF" text="#000000"> Hi all, <masayag> suggested me to send this email after our discussion on IRC.
