Hello, I have a little trouble with ovirt 3.5 on CentOS6.6: I was removing all networks from all hosts.
Did you use the setup networks dialog from the UI in order to remove those networks ? Or have you removed those networks from the host directly (where you should used the: 1. virsh net-destroy 'the-network-name' 2. virsh net-undefine 'the-network-name' ) can you report the output of 'virsh -r net-list' ?
Then after removing network from data center the hosts went to unusable.
What was the host's status prior to removing its networks ? Was it up ?
Every time after reinstall the host claims that the network is not configured, but it s already removed from network tab in DC.
What is the missing network name ? Is it 'ovirtmgmt' ?
Where from it gets the old configuration? the old interfaces also restored every time on the reinstalled hosts.
The hosts via vdsm reports their network configuration via the 'getCapabilities' verb of vdsm. You can try running it on the host: vdsClient -s 0 getVdsCaps and examine the nics / neworks / bridges / vlans / bonds elements.
Which DB table is in charge of dc-networks?
The retrieved information from vdsm is reported to 'vds_interace' table. The dc networks are stored in 'networks' table and networks attached to clusters are stored in network_cluster table. I wouldn't recommend on deleting entries from the tables directly. There are certain constraints which shouldn't be violated, i.e. the management network 'ovirtmgnt' is blocked for removal from the engine.
Thanks, Arman.
