Re: Migrate hosted engine to standalone host
by Anton Louw 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.

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.....

Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. 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.
