The administration guide related to host management is here:
https://ovirt.org/documentation/admin-guide/chap-Hosts/
but it doesn't cover the change of the host network configuration.
Dan and Marcin or some other sysadmin in this list may correct me, but I
think the correct procedure here is:
- Put the host to maintenance in the ovirt interface
- change the nic settings in ovirt web interface
- activate the host

Derek, we should probably ensure this case is covered in the Admin guide.
