[Users] ovirt-node post-reboot no persistent networks config .. !!! urgent update req for POC coming weekend

[Sven Kieske]

Hi,

we were now able to test this.

The IP does not show up in ovirt-node-setup TUI, however if you drop to
console you see this:

[root at vroot4 ~]# ip a s

13: bond1: <BROADCAST,MULTICAST,MASTER> mtu 1500 qdisc noop state DOWN
    link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff

    link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff

So the address gets switched from eth1 to the virtual nic "ovirtmgmt"
and does not show up in the TUI.

Is this an intended behavior?
Furthermore, for what reason does ovirt create all those bonding devices?

We installed the el6 variant of the iso.

An additional info, which I noticed:

lsb_release -a does not provide a correct output, it just states:

"RedHatEnterpriseVirtualizationHypervisor" which is not very
informative, no version information or whatsoever.

Regards

Sven
