<p class="MsoNormal"><span lang="EN-US">Last time this worked, when I ran a “kayobe overcloud host configure” (the node had network connection) but then “kayobe overcloud service deploy” killed the network when it started the Openvswitch.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Now (today) this configuration doesn’t even allow to reach the network/(to be)neutron nodes (they lose network connection) when the playbook restarts system-networkd. It already creates OVS PHY bridges and lots of stuff
even though I ran “overcloud service destroy” before that. Should it do that at this stage?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Are there any examples to set up a network node with bonds and vlans and external neutron networks out there? Any suggestions?<o:p></o:p></span></p>
