HostedEngine add more RAM
by Joseph Goldman
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
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.

Subject: [ovirt-users] Migrate hosted engine to standalone host
Hi All,
So I have been playing around a bit, and I would just like some recommendations.
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

Bridge not forwarding frames on node.
by s.danzi
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.....

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

http://centos.mirror.garr.it/centos/8.1.1911/isos/x86_64/CentOS-8.1.1911-...
- 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-...
; 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.

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

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

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.
Notes:
- oVirt Appliance is already available for CentOS Linux 8
