Re: [ovirt-users] Hosted engine deploy: problem with the rDNS of another iface

But bond0/192.168.10.225 is the only interface I have (right now) to connect to the machine. So, I should create another interface, dedicated to management? Right now I'm using bond0 as the source iface for the mgm bridge.
