Fresh 4.2 install: engine-setup skipping NFS share step
by davemintz64＠gmail.com 03 Jul '18

03 Jul '18

Any idea why the install script is not asking me if I want to set up the local ISO nfs share? I thought it might be because I am using the entire disk, but I tried creating a separate partition/mount for ti and it still didn't work. This is what I see: --== APACHE CONFIGURATION ==-- Setup can configure the default page of the web server to present the application home page. This may conflict with existing applications. Do you wish to set the application as the default page of the web server? (Yes, No) [Yes]: Setup can configure apache to use SSL using a certificate issued from the internal CA. Do you wish Setup to configure that, or prefer to perform that manually? (Automatic, Manual) [Automatic]: --== SYSTEM CONFIGURATION ==-- [The NFS questions should be here but it is blank] --== MISC CONFIGURATION ==-- Please choose Data Warehouse sampling scale: (1) Basic (2) Full Thanks in advance.

ovirt-guest-agent-common version and repo
by Gianluca Cecchi 03 Jul '18

03 Jul '18

Hello, on CentOS 7.x VM with epel enabled it seems that latest package is ovirt-guest-agent-common-1.0.14-1.el7.noarch and from its changelog it seems far from being up 2 date and released before 4.2.0 release... * Thu Nov 02 2017 Tomáš Golembiovský <tgolembi(a)redhat.com> - 1.0.14-1 - Bump to version 1.0.14 - Changed link to upstream sources Am I doing something wrong with it and its repo or is it not so important component even after upgrading to oVirt 4.2.x? Thanks, Gianluca

Ovirt and L2 Gateway
by carlgrundholm＠gmail.com 03 Jul '18

03 Jul '18

I have install ovirt 4.2.3 and everything seems to be working fine: I can create virtual (Geneve overlay) networks for communication between virtual machines via the external provider ovirt-provider-ovn by using the OWS switch on the cluster. Live migrations and everything else within the virtual environment works perfectly :-) For connections from virtual machines to physical VLAN's in a switch, I can also create a logical network which is created using the external provider ovirt-provider-ovn by specifying a connection to a physical VLAN network created as a separate data center network. This method requires that all ovirt-nodes (hosts) in the cluster have access to the physical network though. What I am looking for is a way to implement a L2 Gateway such that (not all) ovirt nodes (hosts) need to have direct access to the physical network. What I am looking for is a way where virtual machines can communicate with the L2 Gateway via virtual (Geneve overlay) networks. On the L2 Gateway the virtual network shall then be bridged to the physical VLAN on a dedicated network interface. My goal is that the virtual network and the physical network becomes one big broadcast domain. This concept has been described by different people on the Internet such as these articles: - https://weiti.org/ovn/2018/01/03/ovn-l2-breakout-options - https://wiki.openstack.org/wiki/Neutron/L2-GW How can I accomplish something similar in an ovirt-environment? Thanks in advance, Carl Grundholm

Dedicated underlay network for overlay traffic
by carlgrundholm＠gmail.com 03 Jul '18

03 Jul '18

I am going to be using OVN Geneve overlay networks extensively and I expect a lot of traffic on the underlay network being used for transmission of the tunnel traffic. In oVirt the default seems to be that the network "ovirtmgmt" is being used for the underlay network - which could cause problems for management traffic if vms are saturating the link with traffic on different OVN overlay networks. When selecting a specific cluster, selecting "Logical Networks" and pressing the "Manage Networks" button it is possible to specify that a specific Data Center Network shall be limited to one or more of the following traffic types: - VM Network - Management - Display Network - Migration Network - Gluster Network - Default Route Here I miss an option called "Underlay Network for OVN Geneve traffic" or similar. Is there a way - e.g. by editing some configuration files on the oVirt engine and on the oVirt nodes - to divert all overlay Geneve traffic away from the management interface unto a dedicated network interface?

Feature: Live migration for High Performance VMs
by Sharon Gratch 02 Jul '18

02 Jul '18

Hi everyone, I would like to share our plan for supporting live migration for High Performance VMs (and in general to all VM types with pinning settings). Implementing this will be done in 2 phases: Phase 1: 1. Only manual live migration will be supported for high performance VMs type. 2. The user will need to manually choose the destination host to migrate his VM to (can't base on scheduler manager to find the most suitable host). 3. Source and destination hosts should have the same hardware and supports the exact same configuration. Phase 2: 1. Both automatic and manual live migration modes will be supported for HP VMs. 2. Destination host can be automatically selected by the engine (scheduler manager). 3. Source and destination hosts should fit but not be necessarily identical. More Details on that can be found on the feature page <https://www.ovirt.org/develop/release-management/features/virt/high-perform…> . Any feedback on this feature will be greatly appreciated. Thanks, Sharon

oVirt HCI point-to-point interconnection
by Stefano Zappa 29 Jun '18

29 Jun '18

Good morning, I would like to kindly ask you a question about the feasibility of defining a point-to-point interconnection between three ovirt nodes. Initially with the idea of optimizing the direct communications between the nodes and especially the gluster communications, and so it would seem quite easy, then evaluating a more complex configuration, assuming to create an overlay L2 network on the three L3 point-to-point, using techniques like geneve, of which at the moment I have no mastery. If the direct routing of three nodes to interconnect the public network with the private overlay network was not easily doable, we could leave the private overlay network isolated from the outside world and connect the VM hosted engine directly to the two networks with two adapters. This layout with direct interconnection of the nodes without switches and a shared L2 overlay network between the nodes may in future be contemplated in future releases of your HCI solution? Thank you for your attention, have a nice day! Stefano Zappa. [cid:609f1f14-f74e-489f-b86d-08647efc6d1c] Stefano Zappa IT Specialist CAE - TT-3 Industrie Saleri Italo S.p.A.

Snapshot error with Cinder/Ceph disk
by Matthias Leopold 29 Jun '18

29 Jun '18

Hi, i'm having problems with snapshotting Cinder/Ceph disks since upgrading to 4.2. Observed behavior has changed between 4.2.2 and 4.2.4. With oVirt 4.2.2 and Cinder 11.1.0 - oVirt snapshot fails (according to oVirt), but is listed in GUI - disk snapshot are visible in oVirt storage domain tab and Cinder CLI - first try to remove the oVirt snapshot fails (according to oVirt), but disk snapshots are removed from oVirt storage domain tab and Cinder CLI - second try to remove oVirt snapshot succeeds With oVirt 4.2.4 and Cinder 11.1.1 - oVirt snapshot fails "completely" - in Cinder logs i can see that disk snapshots are created and immediately deleted oVirt error log message is the same in both cases: "Failed in 'SnapshotVDS' method" I'm attaching logs from oVirt engine from the latter case. thx for any advice matthias

where did virbr0: come from?
by Conrad Jones 29 Jun '18

29 Jun '18

I installed * CentOS * Master repo for ovirt * create ovirtmgmt bridge via network scripts (not virbr0) * installed VDSM * installed cockpit * installed cockpit-ovirt-dashboard.noarch i suspect the virbr0 came from installing the cockpit-ovirt-dashboard.noarch components as it also installed a whole host of stuff like virt-manager-common.noarch Anyway this causes the hosted ovirt-engine vm install to fail from cockpit as "[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "hostname 'host-141' doesn't uniquely match the interface 'enp3s0' selected for the management bridge; it matches also interface with IP [u'192.168.122.1'].
