[Feedback needed] oVirt 4.4.0 Test week
by Sandro Bonazzola 19 May '20

19 May '20

Hi, oVirt team is planning to release oVirt 4.4.0 Ga in the next couple of weeks. oVirt 4.4.0 release candidate was released yesterday and we'd like to gather as much feedback as possible. Please join us testing this release candidate next week, starting Sunday May 10th 2020 till Friday May 15th 2020! We are going to coordinate the testing effort with a public Trello board at https://trello.com/b/5ZNJgPC3/ovirt-440-test-day You'll find instructions on how to use the board there. For joining the board you can use this link: https://trello.com/invite/b/5ZNJgPC3/f1b1826ee4902f348c44607765a15099/ovirt… If you have not an environment dedicated to testing, remember you can set up a few VMs and test the deployment with nested virtualization using your production environment creating a virtual test environment. In this case please be careful avoiding touching the production environment from the testing one. The oVirt team will monitor the Trello board, the #ovirt IRC channel on irc.oftc.net server and the users(a)ovirt.org mailing list to assist with the testing and debugging issues. Basic instructions for setting up a minimal system are available in release candidate announce at: https://lists.ovirt.org/archives/list/announce@ovirt.org/message/3QORBKVKTA… Release notes for this release candidate are available here: https://ovirt.org/release/4.4.0/ Thanks -- 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.

HostedEngine add more RAM
by Joseph Goldman 19 May '20

19 May '20

Hi List, I'm having troubles adding more RAM to my HostedEngine VM. When the cluster first got up and running I only had a little bit of RAM so I only gave the HE 4GB, but i'm constantly getting BadHealth alerts so I want to up it to 8GB. I have tried multiple ways - mostly any time i edit the HE VM through the UI it simply reverts back to 4096MB RAM, never upgrades to 8192MB. I have tried with global HA maintenance on as well but no luck. No errors, it saves as if it has completed the action but when I re-open the VM (or even after a fresh boot) it has simply reverted back to 4096MB. Any help appreciated. Thanks, Joe

Re: Migrate hosted engine to standalone host
by Anton Louw 18 May '20

18 May '20

Hello, I am not sure if the below thread went missing somewhere. Just to add on as well, when moving the hosted engine to a standalone host, will the process look similar to the below: Backup and remove Hosted Engine: 1. Backup Hosted Engine (engine-backup --scope=all --mode=backup --file=Full --log=Log_Full) 2. Download the backup files from HE using WinSCP 3. Enable global Maintenance (hosted-engine --set-maintenance --mode=global) 4. Power down hosted engine (hosted-engine --vm-shutdown) --------------------------------------------------------------------------------------------- Redeploy Hosted Engine: Build new CentOS VM in another environment *Same IP *Same name *Same resources 1. sudo yum install https://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm 2. sudo yum install -y ovirt-engine 3. Copy backup files to newly deployed CentOS VM 4. engine-backup --mode=restore --file=Full --log=Log_Full --provision-db --provision-dwh-db --restore-permissions 5. after retore has completed, run engine-setup Or are there any additional steps I need to take? I have tried this in my one lab environment, and it works without any issues, however when trying this on my second lab environment, everything shows as “down”, ie. Hosts, Data Center and Storage Domains.

I moved my HE from an oVirt node to my VMware environment, basically running as a standalone host now. Is there anything I should look out for? I can see there is a problem when configuring the HE after the move, where it says that global maintenance is not enabled. How will this work if the hosted engine is not sitting on a oVirt node anymore? Any feedback\suggestions will be greatly appreciated. Thanks Anton Louw Cloud Engineer: Storage and Virtualization at Vox ________________________________ T: 087 805 0000 | D: 087 805 1572 M: N/A E: anton.louw(a)voxtelecom.co.za<mailto:anton.louw@voxtelecom.co.za> A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg www.vox.co.za<http://www.vox.co.za> [F]<https://www.facebook.com/voxtelecomZA> [T]<https://www.twitter.com/voxtelecom> [I]<https://www.instagram.com/voxtelecomza> [L]<https://www.linkedin.com/company/voxtelecom> [Y]<https://www.youtube.com/user/VoxTelecom> [#VoxBrand]<https://www.vox.co.za/fibre/fibre-to-the-home/?prod=HOME> Disclaimer The contents of this email are confidential to the sender and the intended recipient.

So after setup of new DC and Storage and Host at 4.3 as the CPU technology is lower than the Hosted-Engine machine. when I try and create a VM the only DC choice is the Default one. Is this Normal or issue with 4.4? Thanks Bryan

Bridge not forwarding frames on node.
by s.danzi 15 May '20

15 May '20

Hi to all!I'm having an issue with networks bridges on ovirt node.It's look like this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1279161On VM I have a bridge between a tap device and network interface. On node side the interface is bridged with bond0 vlan 128 (bond0.128 lacp).When I ping an host on the other side of tap device I can see this:Arp request goes from my lan to the tap device on vm. Arp reply return from tap vm and bridge forward this to vm networks interface. Using tcpdump on vm interface on node I can see the arp reply, using tcpdump on bond0.128 or on bridge I can't see the arp reply. Arp request is forwarded from bond0.128 to vm net but arp reply isn't forwarded from vm net to bond0.128. Very strange.....

This pre-release must not to be used in production. Some of the features included in oVirt 4.4.0 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:12 389-ds - 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. What’s new in oVirt 4.4.0? - 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 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. 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.
