Hello Gianluca,
Add/remove would probably be the simplest way to go. The procedure would be: - take host to maintenance - remove host - use vdsm-cient to change the ip of ovirtmgmt - add the host again
Just changing the dns configuration sounds quite interesting. I suppose the host certificates should be ok if the host was added by hostname.
I've already done something similar in September; see here the full thread: http://lists.ovirt.org/pipermail/users/2017-September/084411.html In that case it was more complicated in the sense that vlan change was involved for ovirtmgmt and I passed through a new cluster. Now it is more simple, but while on September case the hosts were plain CentOS hosts, now they are ovirt-node-ng, so my manual ifcfg files manipulation doesn't fit. If vdsm-client command is ok I presume it will be something of type: # vdsm-client Host setupNetworks vdsm-client: Command Host.setupNetworks with args {} failed: (code=-32603, message=Attempt to call function: <bound method Global.setupNetworks of <API.Global object at 0x2279f10>> with arguments: () error: setupNetworks() takes exactly 4 arguments (1 given)) # with some sort of json configuration, but it is not clear to me what to give Can I do the change of ip from the host web cockpit mgmt interface? I set/change the ip and then eventually reboot the server to see if it works? Gianluca
