Need advise/help/ideas to implement a two sites disaster-recovery with ovirt
by wodel youchi 21 Nov '17

21 Nov '17

Hi, We want to implement two sites with ovirt and have disaster-recovery, if site one is unreachable, then site two takes-over. We will be using iSCSI for Data domains Our initial idea is : - install the first site : - self-hosted engine - iscsi blocks for data domains - install the second site: - self-hosted engine. - iscsi blocks for data domain. Use the snapshot synchronization of the disk-array to sync iscsi blocks/volumes. The two self-hosted engine will be independent. In case of a failure : - break the synchronization - Access the data domain in site two - start the VMs. oVirt does not manage replication of VMs itself, someone may argue that it's not it's purpose, but what about selecting the VMs to replicate?? in case of NFS we may (I don't know really if it's possible) have some access to the VMs disk files, but in block mode with LVM in it, things become complicated. So if someone has implemented such architecture, could you please share the experience, give advice and ideas on how to best implement this.

Issue with ovirt-ansible-roles
by Luca 'remix_tj' Lorenzetto 21 Nov '17

21 Nov '17

Hello, i'm playing with ovirt-ansible-roles for building a standard configuration to be applied to all my ovirt setups. I downloaded ovirt-ansible-roles 1.1.1 from github and unpacked examples, playbooks and roles on a directory (/ansible/ovirt-ansible-roles/). I created then this playbook: ==8<==8<==8<==8<==8<== ovirt_infra.yml ==8<==8<==8<==8<==8<==8<=== --- - name: oVirt infra hosts: localhost connection: local gather_facts: false vars_files: - ovirt_infra_vars.yml - passwords.yml pre_tasks: - name: Login to oVirt ovirt_auth: url: "{{ engine_url }}" username: "{{ engine_user }}" password: "{{ engine_password }}" ca_file: "{{ engine_cafile | default(omit) }}" insecure: "{{ engine_insecure | default(true) }}" tags: - always - name: Generate Hosts list set_fact: hosts: "{{ hosts|default([]) + [ {'name': item.key, 'address': item.key, 'cluster': item.value.cluster, 'password': item.value.password|default('defaultpwd') } ] }}" with_dict: "{{ hosts_map }}" roles: - ovirt-infra post_tasks: - name: Logout from oVirt ovirt_auth: state: absent ovirt_auth: "{{ ovirt_auth }}" tags: - always ==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<=== file passwords.yml declares engine_password, ovirt_infra_vars.yml instead contain this vars: ==8<==8<==8<==8<==8<==8<== ovirt_infra_vars.yml ==8<==8<==8<==8<==8<=== --- engine_url: https://ovirtengine.intranet.company/ovirt-engine/api engine_user: admin@internal engine_insecure: True compatibility_version: 4.1 data_center_name: Default hosts_map: fltiovirt001.intranet.company: cluster: production clusters: - name: production cpu_type: Intel Westmere Family profile: production ==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<==8<=== I did some pre-flight checks and everything seems ok: playbooks > ansible --version ansible 2.4.0.0 config file = /ansible/ovirt-ansible-roles/playbooks/ansible.cfg configured module search path = [u'/home/remixtj/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules'] ansible python module location = /usr/lib/python2.7/site-packages/ansible executable location = /usr/bin/ansible python version = 2.7.5 (default, May 3 2017, 07:55:04) [GCC 4.8.5 20150623 (Red Hat 4.8.5-14)] playbooks > rpm -qa python-ovirt* python-ovirt-engine-sdk4-4.1.6-1.el7ev.x86_64 So i hope that everything goes smooth, but... playbooks > ansible-playbook ovirt_infra.yml [DEPRECATION WARNING]: The use of 'include' for tasks has been deprecated.

Openshift in VMs created from oVirt
by Wayna Runa 21 Nov '17

21 Nov '17

Hi there!, I've oVirt running and providing several VMs (CentOS and RedHat), now I want to provide VMs with minimalist Openshift cluster running inside to developers. Minishift creates a VM with Openshift locally, that is fine, but now we have oVirt to provide VMs which the developers can get access remotely. How I can use oVirt to do that?. Thanks in advance. -- *Wayna Runa*

ovirt node and logical networks on same physical one
by Gianluca Cecchi 21 Nov '17

21 Nov '17

Hello, I'm going to setup an environment where unfortunately I will have only a flat physical class B private network available, for all my scopes. There are 2 stacked switches where the hypervisors' nics will connect to. My hypervisors will have 6 network interfaces so that potentially I could configure 3 bonds: one for mgmt, one for migration, one for VMs. But this way each hypervisor will have its mgmt ip and its migration ip on the same lan and also the IP of a VM running inside it will stay in the same lan. Is this kind of configuration feasible for a test? Any suggestion based on these constraints? If this matter, I'm going to install hypervisors as oVirt nodes Thanks, Gianluca

Info about xeon mp dunnington support
by Gianluca Cecchi 21 Nov '17

21 Nov '17

Hello, I should start configuring a lab environment where I should have available some IBM 3850 M2 servers with E7450 Xeon cpu (also known as Dunnington). Spec page of processor here: https://ark.intel.com/it/products/36941/Intel-Xeon-Processor-E7450-12M-Cach… Can you tell me if they are compatible with oVirt 4.1 for testing; used by anyone on list? Base on this following link I presume it should be detected as Penryn from oVirt, correct? https://en.wikipedia.org/wiki/List_of_Intel_codenames I have not them physically accessible right now but I'm just moving to avoid, if possible, compatibility problems. Thanks, Gianluca

But I couldn't. If there is no abvious workaround, would there be other ways like : - find the bare logical volume, shut down the VM, and play with low level qemu-img commands. I think I knwn how to do that, but I'm worried the oVirt database won't be in sync once I've removed the snapshot or - export the VM then re-import, if this is related to some LV space missing. Then removing the snapshot the usual way. Any advice (apart the obvious upgrade-to-4.X-sir)? -- Nicolas ECARNOT

using oVirt with newer librbd1
by Matthias Leopold 18 Nov '17

18 Nov '17

Hi, we want to use a Ceph cluster as the main storage for our oVirt 4.1.x datacenter. We successfully tested using librbd1-12.2.1-0.el7 package from Ceph repos instead of the standard librbd1-0.94.5-2.el7 from CentOS 7 in an oVirt virtualization node. Are there any caveats when doing so? Will this work in oVirt 4.2? thx matthias

Snapshot or not?
by Demeter Tibor 17 Nov '17

17 Nov '17

--=_356f090b-8288-4845-8f3a-5ab9dcf0b36a Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Dear Users, I have a disk of a vm, that is have a snapshot. It is very interesting, because there are two other disk of that VM, but there are no snapshots of them. I found this while I've try to migrate a storage-domain between two datacenter. Because, I didn't import that vm from the storage domain, I did an another similar VM with exactly same sized thin-provisioned disks. I have renamed, copied to here my originals. The VM started successfully, but the disk that contain a snapshot did not recognized by the os. I can see the whole disk as raw. (disk id, format in ovirt, filenames of images, etc) .

Enabling libgfapi disk access with oVirt 4.2
by Alessandro De Salvo 17 Nov '17

17 Nov '17

Hi, I'm using the latest 4.2 beta release and want to try the gfapi access, but I'm currently failing to use it. My test setup has an external glusterfs cluster v3.12, not managed by oVirt. The compatibility flag is correctly showing gfapi should be enabled with 4.2: # engine-config -g LibgfApiSupported LibgfApiSupported: false version: 3.6 LibgfApiSupported: false version: 4.0 LibgfApiSupported: false version: 4.1 LibgfApiSupported: true version: 4.2 The data center and cluster have the 4.2 compatibility flags as well. However, when starting a VM with a disk on gluster I can still see the disk is mounted via fuse. Any clue of what I'm still missing? Thanks, Alessandro

[ANN] oVirt 4.1.8 First Release Candidate is now available
by Lev Veyde 16 Nov '17

16 Nov '17

The oVirt Project is pleased to announce the availability of the First Release Candidate of oVirt 4.1.8, as of November 16th, 2017 This update is the eighth in a series of stabilization updates to the 4.1 series. Starting from 4.1.5 oVirt supports libgfapi [5]. Using libgfapi provides a real performance boost for ovirt when using GlusterFS . Due to a known issue [6], using this will break live storage migration. This is expected to be fixed soon. If you do not use live storage migration you can give it a try. Use [7] for more details on how to enable it. This release is available now for: * Red Hat Enterprise Linux 7.4 or later * CentOS Linux (or similar) 7.4 or later This release supports Hypervisor Hosts running: * Red Hat Enterprise Linux 7.4 or later * CentOS Linux (or similar) 7.4 or later * oVirt Node 4.1 See the release notes draft [3] for installation / upgrade instructions and a list of new features and bugs fixed. Notes: - oVirt Appliance is already available - oVirt Live is already available[4] - oVirt Node is already available[4] Additional Resources: * Read more about the oVirt 4.1.8 release highlights: http://www.ovirt.org/release/4.1. <http://www.ovirt.org/release/4.1.8/>8 <http://www.ovirt.org/release/4.1.8/>/ <http://www.ovirt.org/release/4.1.8/> * Get more oVirt Project updates on Twitter: https://twitter.com/ovirt * Check out the latest project news on the oVirt blog: http://www.ovirt.org/blog/ [1] https://www.ovirt.org/community/ [2] https://bugzilla.redhat.com/enter_bug.cgi?classification=oVirt [3] http://www.ovirt.org/release/4.1. <http://www.ovirt.org/release/4.1.8/>8 <http://www.ovirt.org/release/4.1.8/>/ <http://www.ovirt.org/release/4.1.8/> [4] http://resources.ovirt.org/pub/ovirt-4.1-pre/iso/ [5] http://staged-gluster-docs.readthedocs.io/en/release3.7.0beta1/Features/lib… [6] https://bugzilla.redhat.com/show_bug.cgi?id=1306562 [7] http://www.ovirt.org/develop/release-management/features/storage/glusterfs-… -- Lev Veyde Software Engineer, RHCE | RHCVA | MCITP Red Hat Israel <https://www.redhat.com> lev(a)redhat.com | lveyde(a)redhat.com <https://red.ht/sig> TRIED.

Are the external leases helping on MasterDomain failure?
by Arman Khalatyan 16 Nov '17

16 Nov '17

Hi, Is this document still valid? https://www.ovirt.org/develop/release-management/features/storage/vm-leases/ If yes, I have a n question concerning the local SSD leases: If the HA leases are going to the local host ssd storage, then due to the Master Domain failure the HA will continue to run? Or in which scenario external leases are helping to keep HA VM up and running? thanks, Arman.
