Non-RHEL RPMs gone after RHV-H upgrade
by Colin Coe 11 Jan '18

11 Jan '18

Hi all We're running RHV 4.1.6. Yesterday I upgraded the RHV-H nodes in our DEV environment to 20180102 and found that all the non-RHEL RPMs are now gone. Their associated config files in /etc are still there. The RPMs in question were from HPE SPP plus a monitoring system client (Xymon). I had thought that non-RHEL RPMs would persist after a host upgrade. Am I wrong on this? Thanks CC

oVirt Node 4.1 question, writing files to /root and RPMs
by Matt Simonsen 11 Jan '18

11 Jan '18

Hello all, I read at https://www.ovirt.org/develop/projects/node/troubleshooting/ that "Changes made from the command line are done at your own risk. Making changes has the potential to leave your system in an unusable state." It seems clear that RPMs should not be installed. Is this accurate for https://www.ovirt.org/node/ ? We have added smartctl and hpacucli in order to do disk and RAID monitoring. So far our node servers have retained changes across reboots, which is the primary reason I'm wondering if perhaps this applies to an older version of oVirt Node. If what we have been doing is not supported, what is the suggested method to do do hardware monitoring (in particular disks)? Thanks Matt

ovirt-live 4.2 - missing stable ISO? + Networking question - when to setup host & in NM or ifcfg?

Hosted Engine and network isolation
by Luca 'remix_tj' Lorenzetto 10 Jan '18

10 Jan '18

Hello, i just completed the setup of my 4.1 new cluster and i'm validating against a set of certification tests i did in the earlier version. One of the test was consisting on isolating the host where hosted-engine vm is running, setting ports on the switch down. Storage domain hosting the engine is FC. Up to 4.0.4, that was the version we was using during that tests, isolating the host was causing a restart of the engine vm on another available host with the fence of the isolated host. Now, with 4.1.8, isolating the host doesn't restart the engine on the other host, only moves the status of the host2 to EngineUnexpectedlyDown, while host1 is isolated, with the engine vm still running on it. Is this due to storage leases? What should be the right action to take in case of isolated host for moving engine away?

Hi, maybe it was already here, but I haven't found it quickly in archive ;( I upgrade the hosted engine and one hots, my notes and questions. The upgrade goes well, I only needed to manually fix the memy value in database for hosted engine [ ERROR ] schema.sh: FATAL: Cannot execute sql command: --file=/usr/share/ovirt-engine/dbscripts/upgrade/04_02_0140_add_max_memory_constraint.sql [ ERROR ] Failed to execute stage 'Misc configuration': Engine schema refresh failed 1) firewalld after upgrade the hot server, the i needed to stop firewalld. It seems, that, the rules are not generated correctly. The engine was not able to connect to the host. How do I could fix it? 2) old repo removal Could i remove the 4.1 repo? If yes, what is the best way to do that? 3) Hosted Engine HA: Hosted Engine HA on upgraded hosts is 3400, the same as on the 4.1 hosts.

Suggestions on changing hosts' network
by Gianluca Cecchi 09 Jan '18

09 Jan '18

Hello, I have a 4.1 cluster based on FC storage domain. There are 2 hosts that are oVirt node-ng The engine is external to the oVirt environment Currently the network situation for ovirtmgmt is this one: engine on network1 (eg 192.168.1.x/24) host1 and host2 on network2 (eg 192.168.2.x/24) network1 and network2 routed through a gw I have to physically move host1 and host2 so that I should change their ip with one on network1. When I added the hosts in oVirt I used as Hostname/IP field their dns hostname What is the simplest approach? I can also give total downtime without particular problems as this is a test environment. I think I can put all infra into maintenance, change dns configuration but then I have also to change hosts network configuration itself... Possibly the best thing to do is remove/add the hosts? I have some doubts about the workflow to follow for removal/add and if for an oVirt-ng node I can change its ip configuration in an easy way.. perhaps from cockpit and then reboot and connect via cockpit to the new ip Thanks in advance for any suggestion Gianluca

Rebuilding my infra..
by carl langlois 08 Jan '18

08 Jan '18

Hi all After screwing my infra with the update to 4.2 (probably a bad manipulation), i am planning a rebuild of the entire infra. First i want to replace my NFS storage with a glusterfs storage. All documentation tell me that i need 3 hosts.. but for the moment i only have 2 but planning to had more later. So does it make sense to start with 2 hosts and use glusterfs as the storage domain(lets says with a replicate of two with all its limitations). If it make sense, 1- what is the best way to do it. 2- how hard will it be to had the 3rd host when available and make it replica 2+arbiter. Also in a setup where i have 3 hosts (replica 2+arbiter) does all the 3 hosts can run users vm? Thanks for your inputs. Carl

The host is configured with two bonded network interfaces: bond0 =3D management network for hypervisors, setup as active/passive. bond1 =3D network that has VLANs for various network segments for = virtual machines to use, setup as LACP bond to upstream switches. On the host, both networks are operational and work as expected.

ovirt 4.1 hosted engine: Resize or Change "hosted-engine" Data Domain
by yayo (j) 08 Jan '18

08 Jan '18

hi at all, We have the "hosted engine" Data domain on a FC LUN too big for only the hosted-engine so we want to create another little FC LUN and move the hosted-engine vm on this new LUN and destroy old one ... Is there any official workflow or how to to do this operation? Or, someone can guide me? Thank you!

How to simulate update of ng node from 4.1.7 to 4.1.8

Suppose I download both the isos: the fixed one for 4.1.17 here: http://resources.ovirt.org/pub/ovirt-4.1/iso/ovirt-node-ng-installer-ovirt/… and the 4.1.8 here: http://resources.ovirt.org/pub/ovirt-4.1/iso/ovirt-node-ng-installer-ovirt/… and I want to simulate install of 4.1.7 from the iso and then update of the ng node to 4.1.8 without internet access but using in some way the 4.1.8 iso (or something derived from it) on my local lan, how can I do? Thanks, Gianluca

[CORRECTED] Can't create 2nd network for VMs in DMZ zone
by Andrei V 08 Jan '18

08 Jan '18

Hi ! Made a typo in previous message, sorry. I'm having difficulty to utilize 2nd NIC on HP Proliant server in order to connect guest VM to DMZ (engine, node and all other guest VMs are on internal zone). I tried to use PCI passthrough, downed ifcfg-enp3s4f1 on node host, created vNic profile "PCI NIC Passthrough", network named "Node10-NIC2", then Virtual Machines -> Network Interfaces -> nic 2 of type PCI Passthrough and profile above. Unfortunately, guest OS (SuSE Leap 42.3) still don't recognize this NIC. This 2nd NIC is visible on Compute -> Hosts -> Network Interfaces. I can assign it network named "Node10-NIC2". However, right now I'm working from the remote, if node net setup get screwed, it will be a big problem. In the archive I found that this 2nd NIC must be up with no IP and default route. Is this correct definition of ifcfg-enp3s4f1? NetworkManager is disabled on node.

How power-saving schedule policy applied?
by Alex Shen 08 Jan '18

08 Jan '18

This is a multipart message in MIME format. ------=_NextPart_000_0093_01D388B2.B43A6B40 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hi, I'm wondering how to apply power-saving schedule in ovirt cluster(version i= s 4.2.0.2-1.el7.centos)? Is there any instruction or manual with UI snapshots= guidance? That will be appreciated. I've configed all host with ipmilan protocol and test ok. I suppose that power saving policy should converge VMs into hosts one by one. Something like that. From the beginning, all hosts are in 'power off' state, if a VM launch, power saving scheduling module should power on one host, and assign= VM into that host. With many VMs activated, exceeding the threshold, power saving scheduling module should turn on another host. If anyone had played power saving scheduling policy, please share me your scenarios or some hints. Thanks a lot.
