Hi !
I have 2-node oVirt 4.3 installation, with engine running as KVM guest on SuSE file server
(not hosted engine).
Nodes are manually installed on CentOS 7.x (further referred as old node #1 and #2).
I’m going to add 1 additional node, and migrate system to CentOS 8.2 / oVirt 4.4.
Is this correct roadmap, or something can be done in a better way? Here is my plan.
1) Upgrade oVirt Hosted Engine running under KVM / SuSE file server to CentOS 8.2 / oVirt
4.4.
Or its better to install from scratch new CentOS 8.2/oVirt 4.4 and migrate database?
2) Install CentOS 8.2 and oVirt node 4.4 on new server (let’s name it node #3).
3) Migrate virtual machines from old node #1 to the new (#3).
4) Upgrade CentOS on old node #1 to v8.2, and oVirt from web interface. Will that work, or
upgrade CentOS 7 -> 8 will render this process unmanageable due to removal of many
components?
5) Migrate back virtual machines from node #3 to newly upgraded node #1.
6) Repeat step 4 and 5 for old node #2.
I have set of custom shell and python scripts running on engine and nodes, so manual
installation was a way to go.
Thanks in advance for any suggestion(s)
with best regards

Hi !
Something wrong went with this list manager, since July 2 I stopped to
receive e-mails. I can't login with my old password, neither I can reset it.
Is it possible to check by list admins?
Thanks in advance.

Ovirt HE has to be redeployed on a CentOS/EL 8 system and restored from backup.
2) Install CentOS 8.2 and oVirt node 4.4 on new server (let’s name it
node #3).
3) Migrate virtual machines from old node #1 to the new (#3).
4) Upgrade CentOS on old node #1 to v8.2, and oVirt from web interface.

You actually remove old#1 and then wipe and reinstall on EL8.
5) Migrate back virtual machines from node #3 to newly upgraded node
#1.
6) Repeat step 4 and 5 for old node #2.

nodes, so manual installation was a way to go.
I would recommend you to create 3 VMs on your Ovirt (with nested Virtualization enabled)
and test your plan on those VMs.

Hi,
Before upgrade make sure your setup upgraded to latest
ovirt-4.3.Recommending to keep the workloads on the Virtual Machines as
minimal as possible. If you have highly write intensive workloads, then it
will take much longer time sync back data which will lead to the longer
upgrade window.
You should have an additional disk(all hosts) for the new voirt 4.4 hosted
engine deployment.
