Devstack with ESXi Compute Node

 

Hi,

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.

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
http://docs.openstack.org/trunk/openstack-compute/admin/content/vmware.html.

I then modified the devstack/stack-screenrc file to hold just these lines
below and started rejoin-stack.sh.

screen -t q-agt bash
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"
screen -t n-cpu bash
stuff "cd /opt/stack/nova && sg libvirtd /opt/stack/nova/bin/nova-compute^M"


But I get the following error:

This is my nova.conf lines related to vmware.

Any help will be appreciated.
