Hi!

Both. My immediate problem is in email 17 May "Cannot sync networks" (existing setup) with no answer as yet. But I need to do this again even if I start over (see detail below - I tried but it isn't working so if there's a better way I'd like to know)...

So essentially, the network I use for setup isn't the same as the final production network for various reasons - one of them being the installers requirements re reachability and connectivity; the other that the test lab has a different subnet and I need to get it working there first; third requirement is isolation of the management network once setup is complete.

I've almost managed to achieve this by putting the engine into global maintenance, shut down engine, manually changing the network config on the hosts (incl vdsm) and engine, rebooting all hosts (which eventually brings the engine back up), re-configuring logical networks and syncing the networks - this all works except the sync - it goes on for a few minutes, then reports lost connectivity to the host and I presume resets the network config - i.e. the sync doesn't succeed. Besides the hosts showing network not synced all functionality except migration seems to be working (all hosts visible and reachable and I can start a VM on any of them)....

Thanks very much,

Roderick

Hi!

​Do you have any existing setup that you want to migrate or you're only planning?

Good day

I would like to change the IP addresses of the host networks used by Ovirt including the ovirtmgmt bridge. I need to move them to a different subnet post installation. What is the best/safest way to do this?

Thanks,
