[ovirt-users] Non-Operational state because management interfaces down

Wed Nov 19 12:42:45 UTC 2014

<html><bodyHi Lior,

  Engine has both networks (ovirtmgmt as eth0 and data as eth1). Internally the cluster should communicate via ovirtmgmt (installed using internal name for ovirtmgmt IP and this network is strictly local to the ovirt cluster). I'm reaching web of engine via data IP (public network as web is listening on all interfaces).

I'm sorry for worse responses as I'm on a business trip for next few weeks.

Cheers,

Luf

Hey,

Thanks, so how come node2 moves to non-operational state rather than
non-responsive (i.e. how come it's reachable from the engine)? The IP
address via which it was installed, belongs to which network interface?
bond1 which is used for data?

Lior.
