Terraform - Ovirt - seting or get some parameters
by Michal Obeslo 26 May '20

26 May '20

Hi all, we need a help, we have problem to set and get IP Address when we created virtual machine when we use terraform. step by step: what we created 1) we created virtual machine Debian 9 - installed the software ovirt-guest-agent) [systemctl status ovirt-guest agent = OK - we created private and public key to connectivity from another computer by .ssh ) /Jenkins Slave/ 2) we created template from virtual machine Debian 9 - set this parameter in template initial Run > user, set static IP in Ovirt Managemet 3) downloaded project from GitHub - create virtual machine from template - terraform main file = OK ? - terraform init = OK - terraform apply = OK : yes create new virtual machine = OK start automatically virtual machine = OK - when I check IP Address > IP address not set - when I check settings in Ovirt management > network > NOT SET - virtual machine not has IP addres > not working - when I change settings in Ovirt management in template Debian from Static IP dhcp > to DHCP - when I check settings in Ovirt management > network > IP in Ovit have DHCP, Virtual machine have dhcp OK But wee need set static IP to Virtual machine and get this IP from terraform. Thank you all. Best regard Michal --- This is the file main.tf: provider "ovirt" { url = "${var.ovirt_url}" username = "${var.ovirt_username}" password = "${var.ovirt_password}" } terraform { backend "local" { path = "terraform.tfstate" } } # Create VM call temp02 module "temp01-pipeline" { source = "../modules/vms" vm_authorized_ssh_key = "${file(pathexpand("c:/cygwin64/home/Administrator/.ssh/id_rsa.pub"))}" vm_custom_script = " ${file(pathexpand("c:/Jenkins/workspace/AT_PipelineVM/config/basic/terraform/ovirt/init_script.yml"))}" cluster_id = "aa583cf2-a07a-11e8-aa92-525400491e5b" vm_name = "cd-pipeline-1.0.0" vm_memory = "4096" vm_cpu_cores = "1" vm_template_id = "876a260b-26c7-482e-bc19-19b10b9c48bb" vm_hostname = "temp01.example.com" vm_user_name = "root" vm_dns_servers = "8.8.8.8" vm_dns_search = "example.com" vm_timezone = "Africa/Nairobi" vm_nic_device = "env3" vm_nic_ip_address = "192.168.26.36" vm_nic_gateway = "192.168.26.2" vm_nic_netmask = "255.255.255.0" }

How to change IP range of node and hosted engine without break anything ?
by Stéphane Paillet 26 May '20

26 May '20

Hello, I installed an ovirt node and its hosted engine in a lab. After several difficulties to install the engine (I don't know why, I didn't have any problem in the past), I would like to change IPs of both to put them on another vlan. How can I do that without break anything ? My main fear is that the data domain used by the hosted engine use the IP of the node rather than its FQDN. I change other data domains paths, but don't find how to change this one, 'cause I can't modify it, and I can't detach / delete it to recreate another one. I didn't find how to move the engine on another data domain using the node's FQDN in its path. For now, I don't use DNS, I just updated /etc/hosts defs on both servers. If someone could help me, telling me step by step how to change IPs on each element in good order, I would be grateful. Thank you. Cheers, Stephane

ovirt node 4.4 and infiniband
by Giulio Casella 26 May '20

26 May '20

Hi all, I have in production a 4.3.9 setup of ovirt, based on a standalone engine, not HE. I have 3 datacenters (an 3 clusters). One of these clusters is composed of many tenth of HP blades, accessing storage via InfiniBand (used as normal NICs, via ipoib). They're not the state of the art, but I cannot renew the entire hardware. After a setup of ovirt node 4.4 I cannot see ib0 nic. I managed to see it installing CentOS 8, enabling Mellanox repo (https://linux.mellanox.com/public/repo/mlnx_ofed/latest/rhel8.1/mellanox_ml…) and installing package "mlnx-ofed-basic". In Ovirt Node it's not possible, that package require dependencies from CentOS 8 repos, not present in ovirt repo. Is there any chances to have infiniband NICs working in ovirt? TIA, gc

searching in manager
by Jiří Sléžka 25 May '20

25 May '20

Hi, oVirt 4.3.9.4-1.el7 I am trying to search a vms which has storage domain other than RHEV-SSDStorage so I entered this search string in Manager in Compute / Virtual Machines search form. Storage != "RHEV-SSDStorage" but it looks like all vms are listed. When I try... Storage = "RHEV-SSDStorage" ...it works like expected and only right vms are listed. Also combinations seems does not work. Storage = "RHEV-SlowStorage" or Storage = "RHEV-MidStorage" ...returns 0 rows. Should it work? Cheers, Jiri

how to save stateless disk
by Jiří Sléžka 25 May '20

25 May '20

Hi, I have one vm configured as stateless (useful for example for testing ansible deploying). But now I am in the middle of work and we have planned power outage. If I power down this wm now I will lost my work. It looks like I am unable to create snapshot if vm is in stateless state. Is there any trick how to not loose my stateless state? Is it RFE worth problem? Cheers, Jiri

How to upgrade my cluster to 4.4 without pain (it will be useful not only to me)
by Patrick Lomakin 25 May '20

25 May '20

We have four hosts with self-hosted engines. Installed version of the engine 4.3.9. I have the power reserve to migrate all virtual machines to three hosts and spend on construction on the remaining host. I really want someone to help me make a plan to upgrade and upgrade to version 4.4 without pain. I will describe the configuration in more detail: 4 hosts where ovirt node 4.3.9 was deployed, and then one of them has an ovirt engine with a control panel deployed. In the process the storage was added and everything works fine. In the ovirt settings, when adding a host, I deployed a backup engine (gray crown icon). Backup engine is available on each host and was specially tested when one of the hosts was turned off. "Now as I think it will update and there will be questions immediately." 1. My first step is to remove a free host from the control panel and deploy ovirt node (4.4) on it 2. Next, the question arises: since I have to restore the new engine from backup 4.3.9, will it not show a version incompatibility? 3. If I need to restore the backup, then logically I have to disable all my engines and then restore? 4. When I restore the engine, will my hosts and virtual machines go nowhere? Will hosts with old version 4.3.9 be available? Please do not criticize me and understand correctly - there are over 100 virtual machines with important data. A rough plan could help me minimize serious errors. In addition, I could share my upgrade experience with the real configuration, which could help both developers and administrators. Regards!

Issues encountered performing HE install on 4.3
by Alan G 24 May '20

24 May '20

Hi, I hit a few issues while performing a recent HE install of 4.3. While I managed to find solutions/workarounds to all the problems I thought I might share them here * As defined in the Ansible defaults the temp dir for building the local HE VM is /var/tmp. I was 80M short of the required space and there did not appear to be a (supported) way to specify a different location. I ended up having to do a bind mount of /var/tmp to get me through the install. Would be nice to be able to specify a custom location. * Permissive umask required. Our CIS CentOS 7 build requires that default umask is 027. This breaks the installer as it creates the VM image under /var/tmp as root and cannot then access it as qemu user. As the temp files are cleaned up on failure it took me a while to track this one down. My solution was to temporarily set the umask to 022 for the session while running the installer. It would be nice if the installer either handled this by doing a chmod/chown as required, or at least doing a umask pre-check and failing with a meaningful error. * SSH root login required on host. Again for CIS we have "PermitRoologin no" configured in sshd. This means the add host task fails on the Engine, but instead of a hard failure we get a timeout on the installer. Which left me chasing some imagined routing/bridging/DNS issue. Eventually I realised I could get to the engine logs and found the issue but took several hours. Would be nice if the installer could either support a sudo option or at least perform a root login pre-check and fail with a meaningful error. Thanks, Alan

Same here. I let the installer automatically set the partition configuration. I changed nothing. Same error as you have. On ovirt-node-ng-installer-4.4.0-2020052110.el8

HostedEngine HA Engine Network Status
by Joseph Goldman 21 May '20

21 May '20

Hi List, Running a 3 node setup for a client, i'm constantly having the HostedEngine move itself around, whatever node its on ends up penalizing its score so low that it forces a migrate to the other node. Looking at /var/log/ovirt-hosted-engine-ha/agent.log shows a decent amount of: MainThread::INFO::2020-05-21 15:47:54,742::states::135::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(score) Penalizing score by 319 due to network status What I want to know is how do I get more debug out of this to know what network status its concerned about, so I can go about stablising it. The system is heavily monitored with ping checks, never drops link and never drops ICMP. None of its VM's falter accessing shared NFS space for disk storage so I'm not sure what the concern is. The node will literally over time penalise itself down to ~2000 and then HA agent will want it to swap nodes. It's not necessarily a bad thing but generates a heap of status emails multiple times a day which is just garbage - and makes the HE unavailable sometimes when mid-admin task. Any help is appreciated. Thanks, Joe

Are the Host storage requirements changed in oVirt 4.4?
by Stefano Stagnaro 21 May '20

21 May '20

Seems like the new minimum local storage for an Host is now 63 GiB, compared to the 55 GiB of the 4.3. If so, the four Installation guides should be updated reflecting the new value. Thank you and congratulations for the new release. — Stefano

oVirt and Fedora
by Sandro Bonazzola 20 May '20

20 May '20

If you have followed the oVirt project for a few releases you already know oVirt has struggled to keep the pace with the fast innovation cycles Fedora Project is following. Back in September 2019 CentOS project launched CentOS Stream as a rolling preview of future RHEL kernels and features, providing an upstream development platform for ecosystem developers that sits between Fedora and RHEL. Since then the oVirt project tried to keep the software working on Fedora, CenOS Stream, and RHEL/CentOS but it became quickly evident the project lacked resources to keep the project running on three platforms. Further, our user surveys show that oVirt users strongly prefer using oVirt on CentOS and RHEL. With the upcoming end of life of Fedora 30 the oVirt project has decided to stop trying to keep the pace with this amazing platform, focusing on stabilizing the software codebase on RHEL / CentOS Linux. By focusing our resources and community efforts on RHEL/CentOS Linux and Centos Stream, we can provide better support for those platforms and use more time for moving oVirt forward. -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://www.redhat.com/> [image: |Our code is open_] <https://www.redhat.com/en/our-code-is-open> *Red Hat respects your work life balance.

This removes them, obviously, only from the database, does not connect to them or do anything on them. You'll then have to add them again. You will not be able to do that if there are running VMs on them, I think. So: If you need to keep the VMs up, and have some of them on the hosted-engine hosts, do not use these options, but do test very well, and study the bugs for which these options were added - you can check git log for this file searching this: https://github.com/oVirt/ovirt-engine/commits/master?after=3cd2766ae1576b22… https://github.com/oVirt/ovirt-engine/commit/542e4a318584c8601159b4bd6d576f… Bug-Url: https://bugzilla.redhat.com/1240466 Bug-Url: https://bugzilla.redhat.com/1235200 The engine will still think that it's a hosted-engine, so it will likely be confused. Perhaps --he-remove-storage-vm is enough for that. This is likely to be problematic, see above bugs. If you don't need to keep the VMs up, it's probably safer to just take all of them down, pass also --he-remove-hosts, and then, in the new engine, add back the hosts. Or even: Install a new engine, do not restore the backup, add the hosts, and import the storage domains. > 5. after retore has completed, run engine-setup > > > > Or are there any additional steps I need to take?
