Re: [ovirt-users] ovirtmgmt network change

2016-12-21 Thread Bill Bill 
Hello,



I was able to get this sorted out by editing the IP’s in the database. After I 
edited them so the engine could reconnect to the servers, I simply removed them 
one by one and re-added them to the engine dashboard. So far, they are working 
as expected.



psql engine -c "update vds_static update host_name = 'newIP' where gateway = 
'oldIP';"



After, it complains about the networks being out of sync which is OK. Simply 
reinstall the host – I had to remove them one by one first, add them back, then 
I was able to resync the networks without issue.



Should this be used, always make a backup of the engine first.

Yes, but then that DNS becomes a very bad SPOF for your system, so not
a good idea for a production systems...

AFAIK if you use a DNS name of the host when you add it to an engine, then
its IP could be changed as long as that name continue be resolved to the
host new address.

I am afraid that you cannot change the address of the management
network while the host is attached to Engine. The reason is that
Engine always uses this address to communicate with the host.

You could change it only if you remove the host from Engine, modify
the address manually, and re-add the host using the new address.

Hello,

How can the IP of the hosts be changed? It is greyed out and I need to change 
those. It’s the only thing I’m not able to change..
