i tried to start 5 instance on my "litle cloud". I have one controller node (tb22) with nova-api and compute. An i have one compute node (tb23). I get an error message in nova-schedule:

2014-07-09 13:00:23.858 ERROR nova.scheduler.filter_scheduler [req-f699a7d3-e3de-40e4-b291-9ae972c7d8f9 admin demo] [instance: 55febf3d-1d56-4381-a6ca-b4b3b37e92e0] Error from last host: tb23 (node tb23): [u'Traceback (most recent call last):\n', u' File "/opt/stack/nova/nova/compute/manager.py", line 1305, in _build_instance\n set_access_ip=set_access_ip)\n', u' File "/opt/stack/nova/nova/compute/manager.py", line 393, in decorated_function\n return function(self, context, *args, **kwargs)\n', u' File "/opt/stack/nova/nova/compute/manager.py", line 1717, in spawn\n LOG.exception((\'Instance failed to spawn\'), instance=instance)\n', u' File "/opt/stack/nova/nova/openstack/common/excutils.py", line 68, in exit\n six.reraise(self.type_, self.value, self.tb)\n', u' File "/opt/stack/nova/nova/compute/manager.py", line 1714, in _spawn\n block_device_info)\n', u' File "/opt/stack/nova/nova/virt/libvirt/driver.py", line 2262, in spawn\n

Has anybody an idea what the fault is? Thanks

This is error is caused by configuration mistake in

/etc/neutron/plugins/ml2/ml2_conf.ini 

Fix

Edit /etc/neutron/plugins/ml2/ml2_conf.ini on both compute and network node

Change tunnel_type = gre to tunnel_types = gre

Restart these services in network node

service openvswitch-switch restart

service neutron-plugin-openvswitch-agent restart

service neutron-l3-agent restart

service neutron-dhcp-agent restart

service neutron-metadata-agent restart

Restart these services in compute node

service openvswitch-switch restart

service nova-compute restart

service neutron-plugin-openvswitch-agent restart
