How to run oVirt on CentOS 8 (or 8.1 or Stream)
by Nate Revo 13 Dec '19

13 Dec '19

I have a system that requires the 4x kernel to run and wanted to run oVirt on top of CentOS. Seems as I'm looking around, rhel/centos 8 support for ovirt is slated for v 4.4. What's the progress with running on Centos 8+ and how do I run ovirt on Centos 8, now. Thanks in advance, -Nate Revo P.S.

ovirt vdsm and networking
by kim.kargaard＠noroff.no 13 Dec '19

13 Dec '19

Hi, We are running CentOS and ovirt 4.3.4. We currently have four nodes and have set up the networks as follows: ovirtmanagmeent network - set up as a tagged vlan with a static IP SAN network - set up as a tagged vlan with a static IP student network - set up as a tagged vlan fw network - set up as a tagged vlan The ovirtmanagement and SAN networks were configured on the CentOS boxes during after installing CentOS and before adding the nodes as hosts. The student network and the fw network were configured through the ovirt admin panel. However, because of this, the student network is not assigned a static IP on the nodes and serves the VM's using the DHCP on the firewall. The ovirt management network is set as the display network and every time I try to change that to the student network, ovirt admin panel tells me that I can't because there is no IP address assigned to the student network vlan. I tried using ip addr add to add a static IP on the one CentOS node, but this does not get picked up by ovirt and of course ovirt controls the actual vlan files on the CentOS box through VDSM, so any changes I make there will likely just be overwritten. So, my question is, should I stop VDSM, add the IP to the vlan files on the CentOS nodes and then restart VDSM or is there a proper way of solving this? I need the Display Network to be set to the student network. Thank you for any help. Kim

oVirt 4.4.0 Alpha release is now available for testing
by Sandro Bonazzola 13 Dec '19

13 Dec '19

oVirt 4.4.0 Alpha release is now available for testing The oVirt Project is excited to announce the availability of the alpha release of oVirt 4.4.0 for testing, as of December 13th, 2019 This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics on top of oVirt 4.3. Important notes before you try it Please note this is an Alpha release. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not to be used in production, and it is not feature complete. In particular, please note that upgrades from 4.3 and future upgrades from this alpha to the final 4.4 release from this version are not supported. Some of the features included in oVirt 4.4.0 Alpha require content that will be available in CentOS Linux 8.1 which is currently being built from Red Hat Enterprise Linux 8.1. If you want to have a better experience you can test oVirt 4.4.0 Alpha on Red Hat Enterprise Linux 8.1. Known Issues - After installation open the Default cluster and hit “Save”, for any other new Cluster using CPU autodetection the dialog needs to be explicitly saved after the detection happens, after first host is added. (bug https://bugzilla.redhat.com/1770697) - Migrate, Cluster Upgrade, Export VM buttons cannot be clicked. Fixed in ovirt-engine-ui-extensions-1.0.11 Installation instructions For the engine: either use appliance or: - Install CentOS Linux 7.7 minimal from http://centos.mirror.garr.it/centos/7.7.1908/isos/x86_64/CentOS-7-x86_64-Mi… - yum install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - yum update (reboot if needed) - yum install ovirt-engine - engine-setup For the nodes: Either use oVirt Node ISO or: - Install CentOS Linux 8.0 from http://centos.mirror.garr.it/centos/8.0.1905/isos/x86_64/CentOS-8-x86_64-19… ; select minimal installation - yum config-manager --set-enabled PowerTools - yum install https://resources.ovirt.org/pub/yum-repo/ovirt-release44-pre.rpm - yum update (reboot if needed) - Attach the host to engine and let it be deployed. What’s new in oVirt 4.4.0 Alpha? - Hypervisors based on CentOS Linux 8 (rebuilt from award winning RHEL8), for both oVirt Node and standalone CentOS Linux hosts - Easier network management and configuration flexibility with NetworkManager - VMs based on a more modern Q35 chipset with legacy seabios and UEFI firmware - Support for direct passthrough of local host disks to VMs - Live migration improvements for High Performance guests. - New Windows Guest tools installer based on WiX framework now moved to VirtioWin project - Dropped support for cluster level prior to 4.2 - Dropped SDK3 support - 4K disks support - Exporting a VM to a data domain - Editing of floating disks - Integrating ansible-runner into engine, which allows a more detailed monitoring of playbooks executed from engine - Adding/reinstalling hosts are now completely based on Ansible - The OpenStack Neutron Agent cannot be configured by oVirt anymore, it should be configured by TripleO instead This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 7.7 or later (but < 8.0) * CentOS Linux (or similar) 7.7 or later (but < 8.0) This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.0 or later * CentOS Linux (or similar) 8.0 or later * oVirt Node 4.4 based on CentOS Linux 8.0 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed. If you manage more than one oVirt instance, OKD or RDO we also recommend to try ManageIQ <http://manageiq.org/>. In such a case, please be sure to take the qc2 image and not the ova image.

Re: Still having NFS issues. (Permissions)

Why do you use 'all_squash' ? all_squashMap all uids and gids to the anonymous user. Useful for NFS-exported public FTP directories, news spool directories, etc. The opposite option is no_all_squash, which is the default setting.

These are the permissions used for volumes on file based storage: lib/vdsm/storage/constants.py:FILE_VOLUME_PERMISSIONS = 0o660 but I am guessing with the addition of the "anonuid=36,anongid=36" to the exports, everything is now working as expected. The VM will boot and run as expected. There was nothing in the any of the documentation which alluded to possibly needed the additional options in the NFS export options. I this is a libvirt issue, it tries to access volumes as root, and without anonuid=36,anongid=36 it will be squashed to nobody and fail. Nir

Hosted Engine Failover Timing
by Robert Webb 12 Dec '19

12 Dec '19

So in doing some testing, I pulled the plug on my node where the hosted engine was running. Rough timing was about 3.5 minutes before the portal was available again. I searched around first, but could not find if there was any way to speed of the detection time in order to reboot the hosted engine quicker. Right now I am only testing this and will add in VM's later, which I understand should reboot a lot quicker.

Did a change in Ansible 2.9 in the ovirt_vm_facts module break the hosted-engine-setup?
by thomas＠hoberg.net 12 Dec '19

12 Dec '19

I am having problems installing a 3-node HCI cluster on machines that used to work fine.... and on a fresh set of servers, too. After a series of setbacks on a set of machines with failed installations and potentially failed clean-ups, I am ssing a fresh set of servers that had never run oVirt before. Patched to just before today's bigger changes (new kernel..) installation failed during the setup of the local hosted engine first and when I switched from GUi to script setup 'hosted-engine --deploy' *without* doing a cleanup this time, it progressed further to the point where the local VM had actually been teleported onto the (gluster based) cluster and is running there. In what seems the absolutely final action before adding the other two hosts, ansible is doing a finaly inventory of the virtual machine and collects facts or rather information (that's perhaps the breaking point) about that first VM before I would continue, only the data structure got renamed between ansible 2.8 and 2.9 according to this: https://fossies.org/diffs/ansible/2.8.5_vs_2.9.0rc1/lib/ansible/modules/clo… And the resulting error message from the /var/log/ovirt-hosted-engine-setup/ovirt-hosted-engine-setup-*.log file is: 2019-12-04 13:15:19,232+0000 ERROR otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:107 fatal: [localhost]: FAILED! => {"ansible_facts": {"ovirt_vms": [{"affinity_labels": [], "applications": [], "bios": {"boot_menu": {"enabled": false}, "type": "i440fx_sea_bios"}, "cdroms": [], "cluster": {"href": "/ovirt-engine/api/clusters/6616551e-1695-11ea-a86b-00163e34e004", "id": "6616551e-1695-11ea-a86b-00163e34e004"}, "comment": "", "cpu": {"architecture": "x86_64", "topology": {"cores": 1, "sockets": 4, "threads": 1}}, "cpu_profile": {"href": "/ovirt-engine/api/cpuprofiles/58ca604e-01a7-003f-01de-000000000250", "id": "58ca604e-01a7-003f-01de-000000000250"}, "cpu_shares": 0, "creation_time": "2019-12-04 13:01:12.780000+00:00", "delete_protected": false, "description": "", "disk_attachments": [], "display": {"address": "127.0.0.1", "allow_override": false, "certificate": {"content": "-----BEGIN CERTIFICATE-----(redacted)-----END CERTIFICATE-----\n", "organization": "***", "subject": "**"}, "copy_paste_enabled": true, "disconnect_action": "LOCK_SCREEN", "file_transfer_enabled": true, "monitors": 1, "port": 5900, "single_qxl_pci": false, "smartcard_enabled": false, "type": "vnc"}, "fqdn": "xdrd1001s.priv.atos.fr", "graphics_consoles": [], "guest_operating_system": {"architecture": "x86_64", "codename": "", "distribution": "CentOS Linux", "family": "Linux", "kernel": {"version": {"build": 0, "full_version": "3.10.0-1062.4.3.el7.x86_64", "major": 3, "minor": 10, "revision": 1062}}, "version": {"full_version": "7", "major": 7}}, "guest_time_zone": {"name": "GMT", "utc_offset": "+00:00"}, "high_availability": {"enabled": false, "priority": 0}, "host": {"href": "/ovirt-engine/api/hosts/75d096fd-4a2f-4ba4-b9fb-941f86daf624", "id": "75d096fd-4a2f-4ba4-b9fb-941f86daf624"}, "host_devices": [], "href": "/ovirt-engine/api/vms/dee6ec3b-5b4a-4063-ade9-12dece0f5fab", "id": "dee6ec3b-5b4a-4063-ade9-12dece0f5fab", "io": {"threads": 1}, "katello_errata": [], "la rge_icon": {"href": "/ovirt-engine/api/icons/9588ebfc-865a-4969-9829-d170d3654900", "id": "9588ebfc-865a-4969-9829-d170d3654900"}, "memory": 17179869184, "memory_policy": {"guaranteed": 17179869184, "max": 17179869184}, "migration": {"auto_converge": "inherit", "compressed": "inherit"}, "migration_downtime": -1, "multi_queues_enabled": true, "name": "external-HostedEngineLocal", "next_run_configuration_exists": false, "nics": [], "numa_nodes": [], "numa_tune_mode": "interleave", "origin": "external", "original_template": {"href": "/ovirt-engine/api/templates/00000000-0000-0000-0000-000000000000", "id": "00000000-0000-0000-0000-000000000000"}, "os": {"boot": {"devices": ["hd"]}, "type": "other"}, "permissions": [], "placement_policy": {"affinity": "migratable"}, "quota": {"id": "7af18f3a-1695-11ea-ab7e-00163e34e004"}, "reported_devices": [], "run_once": false, "sessions": [], "small_icon": {"href": "/ovirt-engine/api/icons/dec3572e-7465-4527-884b-f7c2eb2ed811", "id": "dec3572e-7465-4 527-884b-f7c2eb2ed811"}, "snapshots": [], "sso": {"methods": [{"id": "guest_agent"}]}, "start_paused": false, "stateless": false, "statistics": [], "status": "unknown", "storage_error_resume_behaviour": "auto_resume", "tags": [], "template": {"href": "/ovirt-engine/api/templates/00000000-0000-0000-0000-000000000000", "id": "00000000-0000-0000-0000-000000000000"}, "time_zone": {"name": "Etc/GMT"}, "type": "desktop", "usb": {"enabled": false}, "watchdogs": []}]}, "attempts": 24, "changed": false, "deprecations": [{"msg": "The 'ovirt_vm_facts' module has been renamed to 'ovirt_vm_info', and the renamed one no longer returns ansible_facts", "version": "2.13"}]} If that is the case, wouldn't that imply that there is no test case that covers the most typical HCI deployment when Ansible is updated?

Re: HCL: 4.3.7: Hosted engine fails
by Ralf Schenk 12 Dec '19

12 Dec '19

Hello, hosted engine deployment simply fails on EPYC with 4.3.7. See my earlier posts "HostedEngine Deployment fails on AMD EPYC 7402P 4.3.7". I was able to get this up and running by modifying HostedEngine VM XML while Installation tries to start the engine. Great fun ! virsh -r dumpxml HostedEngine shows: <cpu mode='custom' match='exact' check='partial'> <model fallback='allow'>EPYC</model> <topology sockets='16' cores='4' threads='1'/> <feature policy='require' name='ibpb'/> <feature policy='require' name='virt-ssbd'/> which is not working. I removed the line with virt-ssbd via virsh edit and then it was able to start Engine. To modify the defined HostedEngine you need to create an account for libvirt via saslpasswd2 to be able to "virsh edit HostedEngine" saslpasswd2 -c -f /etc/libvirt/passwd.db admin@ovirt so your Passdb shows: sasldblistusers2 /etc/libvirt/passwd.db vdsm@ovirt: userPassword admin@ovirt: userPassword If the HostedEngine runs afterwards let it run so it updates the persitent configuration in hosted-storage. I also modified these by untarring and maniplulating the correspondent XML-Strings !. Really ugly and disfunctional.
