nova-compute.log of Single Compute node(excerpt): http://paste.openstack.org/show/4956/

Hi,
I assume you'd installed nova-network in the new node as well, what's the content of nova-network.log?
Also, did you restart services, lib-virt, nova-compute and nova-network?
In the dashboard, Is the instance created in Build state and hang in this state? or it is not created?

Thank you for your answer.

> I assume you'd installed nova-network in the new node as well, what's the content of nova-network.log?
nova-network package is installed but service is not invoked(because I won't going to make multi_node HA mode. )

> Also, did you restart services, lib-virt, nova-compute and nova-network?
Y but nova-network.

> In the dashboard, Is the instance created in Build state and hang in this state? or it is not created?
Both exists, but mainly is Build state.

In nova.conf there is no --multi_host flag but on creating network --multihost=T option added by mistake.

I'll try deleting fixed_ip network and recreate without --multihost=T.

In nova-compute.log at single Compute node nova.rpc says {u'failure': None, u'result': [[{u'bridge': u'br400', u'multi_host': True, u'bridge_interface': u'eth0', u'vlan': 400, u'id': 11, u'injected': False, u'cidr': u'172.17.4.32/28', u'cidr_v6': None}, {u'should_create_bridge': True, u'dns': [], u'vif_uuid': u'373a3bc3-5b54-4162-8dbe-566b23e99332', u'label': u'private_2', u'broadcast': u'172.17.4.47', u'ips': [], u'mac': u'02:16:3e:25:fc:2c', u'rxtx_cap': 0, u'should_create_vlan': True, u'dhcp_server': u'172.17.4.41', u'gateway': u'172.17.4.33'}]]}

After I dropped and re-create nova DB(because nova-manage network modify didn't work) and created fixed ip network without multi_host flag, still VM doesn't boot.

Where can I check?

Solved. changed network's multi_host flag from 1 to 0 and VM booted. Thanks.
