Hello,
so far I'm using the nodes host IP@/Interface as well as for the ovirtmgmt network and
host communication.
For performance/security reasons I'd like to move it into private network, dedicated
to oVIRT
as requested... I'l give you more information about my 'problem' ;-)
actual situation:
===========
Host -----------\
----> eth0 10.1.2.3 no VLAN
ovirtmgmt ----/
VMs ----------------> eth1 bridge no IP@ no VLAN
requested situation
==============
Host ---------------> eth0 10.1.2.3 no VLAN
VMs ----------------> eth1 bridge no IP@ no VLAN
ovirtmgmt --------> eth2 192.168.1.2 no VLAN
So, my question is, do I have to declare th IP@ of the ovirtmgmt in the definion of
Cluster/Hosts or can I stay with the host IP@?
Thank you for your help
Hans-Joachim

This change isn't that easy, as you will loose connectivity from oVirt
to your hosts and have to change patch cables. I would do the following:
- configure 192.168.1.x ip on oVirt engine and keep 10.1.2.x address
- put first host into maintenance mode
- configure network on host on CLI to match your requested situation and
patch host accordingly
- edit host and change IP address to 192.168.1.x (or if you're using
DNS-Name/hosts-entry for host communication change this)
- check/refresh network configuration in network tab of this host
- activate host
- repeat steps for all other hosts
As your private ovirtmgmt network is properly not routed, I suggest to
add a display network which is the 10.1.2.0/xx network or use Spice
proxy in order to be able to connect to vm consoles.
Maybe there is an easier way to change your network setup - I would do
it as described above...

René

This change isn't that easy, as you will loose connectivity from

- edit host and change IP address to 192.168.1.x (or if you're
using
DNS-Name/hosts-entry for host communication change this)
Please note that if you are using ssl=True to communicate with the
hosts, and added the host with their IP address, their certificates
would become useless, and you'd have to re-add the hosts to oVirt.
The alternetive of changing the address on the DNS saves you this stage.
If that's your situation, you could even reconfigure ovirtmgmt from
ovirt-engine GUI - just remember to turn off the "connectivity check"
box. After fixing your DNS entry, the reconfigured host should become
reachable again.
- check/refresh network configuration in network tab of this host
- activate host
- repeat steps for all other hosts
As your private ovirtmgmt network is properly not routed, I suggest
to add a display network which is the 10.1.2.0/xx network or use
