Hi Sahina, Either after make the changes in the vdsm.conf,still not able to connect to the replica=2 storage..

What is a data center with local storage?
by Christophe TREFOIS 24 Nov '15

24 Nov '15

Hi, When creating a new data center, in oVirt 3.5 there is the options to have “local” or “shared” storage types. Is there any resource out there that explains the difference between the two? The official doc does not really help there. My current understanding is as follows: In shared mode, I can create data domains that are shared between hosts in a same data center, eg NFS, iSCSI etc. In lcoal mode, I can only create data domains locally, but I can “import” an existing iSCSI or Export domain to move VMs (with downtime) between data centers. 1. Is this correct or am I missing something here? 2. What would be the reason to go for a “local” storage type cluster? Thank you very much for helping out a newcomer :) Kind regards, — Christophe

Failed to create live snapshot

------=_Part_16_134777541.1448296754211 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hello, I'm getting the following error when I try to create a snapshot of one VM. Snapshots of all other VMs work as expected. I'm using oVirt 3.5 on Centos 7. >Failed to create live snapshot 'fsbu3' for VM 'Odoo'. VM restart is recommended. Note that using the created snapshot might cause data inconsistency. I think this is the relevant part of vdsm.log, what strikes me as odd is the line: >Thread-1192052::ERROR::2015-11-23 17:18:20,532::vm::4355::vm.Vm::(snapshot) vmId=3D`581cebb3-7729-4c29-b98c-f9e04aa2fdd0`::The base volume doesn't exist: {'device': 'disk', 'domainID': 'b4e7425a-53c7-40d4-befc-ea36ed7891fc', 'volumeID': '9a7fc7e0-60fc-4f67-9f97-2de4bc08f0a7', 'imageID': 'dfa1d0bf-a1f6-45bb-9574-ab020c0e8c9d'} The part "The base volume doesn't exist" seems interesting. Also interesting is that it does create a snapshot, though I don't know if that snapshot is missing data.

[Need help] Want to write my graduate thesis related to ovirt
by John Hunter 24 Nov '15

24 Nov '15

Hi guys, I am college student who is going to graduate next year, major in CS, I want to work on my graduate thesis related to ovirt. For now I need a project which I can work on for the next 6 month, so I need an idealist which I can reference to write a proposal. I have contributed to #dri-devel during my Google Summer of Code project, so I know how opensource groups works, though workflow are kind of different. I am appreciate if anyone could help, and I hope some one could be my mentor.

I went on and unfortunately "net_persistence = ifcfg" in /etc/vdsm/vdsm.conf and restarting VDSM on the host did not solve it (same error as before). While trying (always without success) all other steps suggested by Simone (binding logical network and synchronizing networks from host) I found an interesting-looking libvirt network definition (autostart too) for vdsm-ovirtmgmt and this recalled some memories from past mailing list messages (that I still cannot find...) ;) Long story short: aborting setup, cleaning up all and creating a libvirt network for each pre-provisioned bridge worked! ("net_persistence = ifcfg" has been kept for other, client-specific, reasons so I don't know if it's needed too) Here it is, in BASH form: for my_bridge in ovirtmgmt bridge1 bridge2; do cat <<- EOM > /root/my-${my_bridge}.xml <network> <name>vdsm-${my_bridge}</name> <forward mode='bridge'/> <bridge name='${my_bridge}'/> </network> EOM virsh -c qemu:///system net-define /root/my-${my_bridge}.xml virsh -c qemu:///system net-autostart vdsm-${my_bridge} rm -f /root/my-${my_bridge}.xml done I was able to connect (with the "virsh" commands above) to libvirtd (which must be running for the above to work) by removing the VDSM-added config fragment, allowing tcp connections and denying TLS-only connections in /etc/libvirt/libvirtd.conf and finally by removing /etc/sasl2/libvirt.conf (all these modifications must be reverted after configuring networks then stopping libvirtd and before relaunching setup).

You're welcome to draf a feature page prior to > coding the fix ;-) I was thinking of adding CIFS/NFSv4 functionality to an hyperconverged cluster (GlusterFS/oVirt) which would have separate volumes for virtual machines storage (one volume for the Engine and one for other vms, with no CIFS/NFSv4 capabilities offered) and for data shares (directly accessible by clients on LAN and obviously from local vms too). Think of it as a 3-node HA NetApp+VMware killer ;-) The UI idea (but that would be the Engine part, I understand) was along the lines of single-check enabling CIFS and/or NFSv4 sharing for a GlusterFS data volume, then optionally adding any further specific options (hosts allowed, users/groups for read/write access, network recycle_bin etc.); global Samba (domain/workgroup membership etc.) and CTDB (IPs/interfaces) configuration parameters would be needed too. I have no experience on a GaneshaNFS clustered/HA configuration with GlusterFS, but (from superficial skimming through docs) it seems that it was not possible at all before 2.2 and now it needs a full Pacemaker/Corosync setup too (contrary to the IBM-GPFS-backed case), so that could be a problem. This VDSM wishlist item was driven by the idea that all actions (and so future GlusterFS/Samba/CTDB too) performed by the Engine through the hosts/nodes were somehow "mediated" by VDSM and its API, but if this is not the case, then I retire my suggestion here and I will try to pursue it only on the Engine/Node side ;) Many thanks for your attention.

FOSDEM16 Virt & IaaS Devroom CFP Extension, Speaker Mentoring, CoC
by Mikey Ariel 23 Nov '15

23 Nov '15

The CFP for the Virtualization & IaaS devroom at FOSDEM 2016 is in full swing, and we'd like to share a few updates with you: ------------------------- Speaker Mentoring Program ------------------------- As a part of the rising efforts to grow our communities and encourage a diverse and inclusive conference ecosystem, we're happy to announce that we'll be offering mentoring for newcomer speakers. Our mentors can help you with tasks such as reviewing your abstract, reviewing your presentation outline or slides, or practicing your talk with you. You may apply to the mentoring program as a newcomer speaker if you: * Never presented before or * Presented only lightning talks or * Presented full-length talks at small meetups (<50 ppl) Submission guidelines: * Mentored presentations will have 25-minute slots, where 20 minutes will include the presentation and 5 minutes will be reserved for questions. * The number of newcomer session slots is limited, so we will probably not be able to accept all applications. * You must submit your talk and abstract to apply for the mentoring program, our mentors are volunteering their time and will happily provide feedback but won't write your presentation for you! If you are experiencing problems with Pentabarf, the proposal submission interface, or have other questions, you can email iaas-virt-devroom at lists.fosdem.org and we will try to help you. How to apply: * Follow the same procedure to submit an abstract in Pentabarf as standard sessions. Instructions can be found in our original CFP announcement: http://community.redhat.com/blog/2015/10/call-for-proposals-fosdem16-virtua… * In addition to agreeing to video recording and confirming that you can attend FOSDEM in case your session is accepted, please write "speaker mentoring program application" in the "Submission notes" field, and list any prior speaking experience or other relevant information for your application. Call for mentors! Interested in mentoring newcomer speakers? We'd love to have your help! Please email iaas-virt-devroom at lists.fosdem.org with a short speaker bio and any specific fields of expertise (for example, KVM, OpenStack, storage, etc) so that we can match you with a newcomer speaker from a similar field. Estimated time investment can be as low as a 5-10 hours in total, usually distributed weekly or bi-weekly. Never mentored a newcomer speaker but interested to try? Our mentoring program coordinator will be happy to answer your questions and give you tips on how to optimize the mentoring process. Email us and we'll be happy to answer your questions! ------------------------- CFP Deadline Extension ------------------------- To help accommodate the newcomer speaker proposals, we have decided to extend the deadline for submitting proposals by one week. The new deadline is **TUESDAY, DECEMBER 8 @ midnight CET**. ------------------------- Code of Conduct ------------------------- Following the release of the updated code of conduct for FOSDEM[1], we'd like to remind all speakers and attendees that all of the presentations and discussions in our devroom are held under the guidelines set in the CoC and we expect attendees, speakers, and volunteers to follow the CoC at all times. If you submit a proposal and it is accepted, you will be required to confirm that you accept the FOSDEM CoC. If you have any questions about the CoC or wish to have one of the devroom organizers review your presentation slides or any other content for CoC compliance, please email iaas-virt-devroom at lists.fosdem.org and we will do our best to help you out.

Cannot setup Networks. The address of the network 'NFS' cannot be modified
by Ihor Piddubnyak 23 Nov '15

23 Nov '15

Trying to change IP for VLAN interface attached to hypervisor, getting vhi2: Cannot setup Networks. The address of the network 'NFS' cannot be modified without reinstalling the host, since this address was used to create the host's certification. Host reinstall does not help. Any clue how to do it? -- Ihor Piddubnyak <ip(a)surftown.com> surftown a/s
