Terraform - Ovirt - seting or get some parameters
by Michal Obeslo 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

The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production. Some of the features included in oVirt 4.4.1 Release Candidate require content that will be available in CentOS Linux 8.2 but can’t be tested on RHEL 8.2 beta yet due to some incompatibility in openvswitch package shipped in CentOS Virt SIG which requires to rebuild openvswitch on top of CentOS 8.2. Installation instructions For the engine: either use appliance or: - Install CentOS Linux 8 minimal from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - dnf module enable -y javapackages-tools pki-deps postgresql:12 - dnf install ovirt-engine - engine-setup For the nodes: Either use oVirt Node ISO or: - Install CentOS Linux 8 from http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-x8… ; select minimal installation - dnf install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - dnf update (reboot if needed) - Attach the host to engine and let it be deployed. This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.1 or newer * CentOS Linux (or similar) 8.1 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.1 or newer * CentOS Linux (or similar) 8.1 or newer * oVirt Node 4.4 based on CentOS Linux 8.1 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.

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!
