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?
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. Will that work, or upgrade CentOS 7 -> 8 will render this process unmanageable due to removal of many components?
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.
I have set of custom shell and python scripts running on engine and 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.
Thanks in advance for any suggestion(s)
