OpenStack Compute (nova)

instance is not starting in second compute-node machine

Asked by TG SASIKUMAR

Hi ,

I am new to this forum and openstack . After adding nova-compute in server2 after that I am unable to create new instance and the details below. Please help to fix this issue.

Server 1 is the base server ( controller ) where all the required services running including nova-compute

Network : eth0 : 192.168.10.6 , eth1 : 192.168.4.1

Server 2 (nova-compute)

In server2 only nova-compute service is running and network configured as eth0: 192.168.10.5 , eth1 : 192.168.4.2

/etc/nova/nova.conf

# Network Specific Settings

--network_manager=nova.network.manager.FlatDHCPManager
--public_interface=eth0
--flat_interface=eth1
--flat_network_bridge=br100
--fixed_range=192.168.20.1/27
--floating_range=192.168.10.6/27
--network_size=32
--flat_network_dhcp_start=192.168.20.33
--flat_injected=False
--force_dhcp

which step do you fail?
lunching an instance may process in th order of scheduling->networking->spawning
and perhaps you can watch your /var/log/nova/nova-compute.log to see if any error reported

yes, you can jump over this problem by commenting it, but you are not able to access instance via novnc from browser
