Now I'm curious, as NetworkManager has been around for couple of years and still it is not finished, why oVirt want to depend of this tool? Wouldn't be better to use libvirt networking features for portability as well and/or talk to libvirt devs to implement features which you would like to see? jbelka ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

I worked in a company where every server had 3 interfaces - 1st install/backup - 2nd service - 3rd admin. In this case ovirtmgmt should be on 3rd interface, not first one. Actually ovirtmgmt is built on top the interface leading towards Engine. I totally hate every autoreconfiguration without confirmation, this style pretends to be more clever that sysadmin and finally it sometimes break whole setup and needs manual reparation. On the other hand, we need to define the management network when a host is added to the setup, and nagging for confirmation for each of them may lead us to the blind baboon acking syndrome. Since I'd like to normalize the way ovirtmgmt is created, and make it more like other networks, I've written up http://www.ovirt.org/Features/Normalized_ovirtmgmt_Initialization If the Add Host dialog had a checkbox saying define ovirtmgmt network automatically, would it satisfy you? (any other comment to that feature page is welcome). regards, Dan. ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
[Users] Network reconfiguration in ovirt 3.1
Hi all System : Fedora 17 On node : Libvirt 0.10 Kernel Linux node1 3.6.10-2.fc17.x86_64 Stable VDSM from repo On manager : Ovirt 3.1 stable Kernel Linux ovirt-manager 3.5.4-1.fc17.x86_64 By default the ovirtmgmt interface is created on node as a bridge with the same parameters than p1p1. That is good so that you keep network working on the node. I've setup a new tagged network on Ovirt, which I have to add to all the node of my cluster. So I plug this new network on p1p2, do not touch to ovirtmgmt network, and apply... and the server is lost. In fact when reconfiguring the network the ovirtmgmt card is set to DHCP, which is the problem. And the only solution to make vdsm back online, is to reset the complete node.
