Hello, I am trying to add a new ovirt-node-ng 4.4.10 node to my cluster managed by an ovirt-engine version 4.4.10. My cluster is composed of other ovirt-node-ng which have been successively updated from version 4.4.4 to version 4.4.10 without any problem. This new node is integrated normally in the cluster, however when I look at the status of the network part in the tab "Network interface" I see that all interfaces are "down". I have a paperclip at the "bond0" interface that says: "Bond state; NONE" I compared the content of "/etc/sysconfig/network-script" between an hypervisor which works and the one which has the problem and I notice that a whole bunch of files are missing and in particular the "ifup/ifdown...." files. The folder contains only the cluster specific files + the "ovirtmgmt" interface. The hypervisor which has the problem seems to be perfectly functional, ovirt-engine does not raise any problem. Have you already encountered this type of problem? Cheers, Renaud
