Hi,<br><br>I started with a single node Devstack(with quantum) on a Ubuntu12.0 server and used a Flat network. It worked fine as I could launch instances and cover many use cases. <br><br>Now I want to added a second compute node to this stack but it has to be an ESXi. So I launched a Ubuntu12.10 VM (using VMWare client) on ESXi and installed Devstack on it aswell(I intended to not start the services which are not needed on it). I then copied over the nova.conf from the first all in one stack node to this and modified the my_ip, VMWare fields etc as per <a href="http://docs.openstack.org/trunk/openstack-compute/admin/content/vmware.html">http://docs.openstack.org/trunk/openstack-compute/admin/content/vmware.html</a>.<br>
<br>I then modified the devstack/stack-screenrc file to hold just these lines below and started rejoin-stack.sh.<br><br>screen -t q-agt bash<br>stuff "python /opt/stack/quantum/bin/quantum-openvswitch-agent --config-file /etc/quantum/quantum.conf --config-file /etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini^M"<br>
screen -t n-cpu bash<br>stuff "cd /opt/stack/nova && sg libvirtd /opt/stack/nova/bin/nova-compute^M"<br><br><br>But I get the following error:<br><br>root@ubuntu1210srvr:/home/stack/devstack# 2013-01-21 22:55:02 INFO nova.virt.driver [-] Loading compute driver 'libvirt.LibvirtDriver'<br>
