I'm working on upgrading an oVirt 3.5 setup. The physical hosts are running CentOS 7, but the hosted engine is CentOS 6. The upgrade notes are "back up the engine, upgrade/reinstall the OS, then restore", but I can't see how to actually install CentOS 7 on the engine.
Am I supposed to re-run "hosted-engine --deploy"? Wouldn't that try to re-register the physical hosts, or can I interrupt it to restore the backup?
Or, is there a way to just attach an install ISO to the engine VM and boot from that?
On 3.6 we release the engine also for el6 so for 3.5/el6 to 3.6/el6 you have just to: - set global maintenance mode, - add the 3.6 repo to the engine VM, - run yum update ovirt-*-setup* on the engine VM - run engine-setup - upgrade the host to 3.6 setting maintenance mode one host at a time - raise the cluster compatibility level Then ee have a specific helper utility for 3.6/el6 -> 4.0/el7: https://www.ovirt.org/develop/release-management/features/hosted-engine-migr...
