Error creating server: test-serverError creating server

problem¶

openstack failed to create instance (instances) from volume (volume) Error creating server: test-serverError creating server. s solution

The following error was encountered while the control node was creating an instance. First make sure the command format is correct.

[root@controller ~]# openstack server create --flavor 0f29be3e-089d-4339-88c1-28b4edf3778b --image df4a76af-1dad-43cc-95c5-6700fee1374d --network 3b92a5e0-db76-4207-82eb-c8d6c392bb1c --block-device uuid=906ff027-3fe1-4d6e-a0f0-aeaaa4b46985 --wait test-server
Error creating server: test-server
Error creating server

Open the /var/log/nova/nova-conductor.log log to check the error report.

WARNING nova.scheduler.utils [req-2ef18f53-7d27-42e7-a367-059ab7f2bfcd ba89422fdc8b4202bbe1fca7a9c358b0 f0be814d573449b2aa0c20178d14195e- default default] [instance: 70222c6a-eb6b-4327-af37-36b4d071d2d7] Setting instance to ERROR state.: MaxRetriesExceeded:Exceeded maximum number of attempts。Exhausted all hosts available for retrying build failures for instance 70222c6a-eb6b-4327-af37-36b4d071d2d7.

Looking at the online solution, you need to check the cat /var/log/neutron/linuxbridge-agent.log file of the neutron of the computing node.

The error reported is as follows:

[root@compute ~]# cat /var/log/neutron/linuxbridge-agent.log
2022-02-22 19:05:03.674 8023 ERROR neutron     % (opt.name, str(ve)))
2022-02-22 19:05:03.674 8023 ERROR neutron ConfigFileValueError: Value for option l                                                                                         ocal_ip is not valid: OVERLAY_INTERFACE_IP_ADDRESS is not IPv4 or IPv6 address
2022-02-22 19:05:03.674 8023 ERROR neutron

It seems that there is a place where the IP address is not configured correctly. I finally found this configuration file on the computing node.

[root@compute neutron]# vim /etc/neutron/plugins/ml2/linuxbridge_agent.ini

# change: 
[vxlan]
enable_vxlan = true
local_ip = OVERLAY_INTERFACE_IP_ADDRESS
l2_population = true

# to:
[vxlan]
enable_vxlan = true
local_ip = 192.168.100.102
l2_population = true

Return to the control node and run the create instance command successfully.
