Hello I use openstack Ussuri in Ubuntu 18 and one controller node and one compute node with two interface, management and Provider that connected to internet i install keystone, glance, placement, nova, neutron on self service option *what i can * i can create provider network and self service network and router between them i can ping router i can launch instance on self service network and it has access to internet and everything looks fine *what i can NOT* I can't launch instances on the provider network. When I launch an instance on the provider network, the provider interface of the compute node will be corrupted and not respond and the instance will not be created.
error in instance :
*Message *Build of instance 2a86a84b-50fc-415c-a15c-cb87398f37ea aborted: Failed to allocate the network(s), not rescheduling. *Code *500 *Details *Traceback (most recent call last): File "/usr/lib/python3/dist-packages/nova/virt/libvirt/driver.py", line 6529, in _create_domain_and_network post_xml_callback=post_xml_callback) File "/usr/lib/python3.6/contextlib.py", line 88, in __exit__ next(self.gen) File "/usr/lib/python3/dist-packages/nova/compute/manager.py", line 513, in wait_for_instance_event actual_event = event.wait() File "/usr/lib/python3/dist-packages/eventlet/event.py", line 125, in wait result = hub.switch() File "/usr/lib/python3/dist-packages/eventlet/hubs/hub.py", line 298, in switch return self.greenlet.switch() eventlet.timeout.Timeout: 300 seconds During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/nova/compute/manager.py", line 2378, in _build_and_run_instance accel_info=accel_info) File "/usr/lib/python3/dist-packages/nova/virt/libvirt/driver.py", line 3663, in spawn cleanup_instance_disks=created_disks) File "/usr/lib/python3/dist-packages/nova/virt/libvirt/driver.py", line 6552, in _create_domain_and_network raise exception.VirtualInterfaceCreateException() nova.exception.VirtualInterfaceCreateException: Virtual Interface creation failed During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/usr/lib/python3/dist-packages/nova/compute/manager.py", line 2200, in _do_build_and_run_instance filter_properties, request_spec, accel_uuids) File "/usr/lib/python3/dist-packages/nova/compute/manager.py", line 2444, in _build_and_run_instance reason=msg) nova.exception.BuildAbortException: Build of instance 2a86a84b-50fc-415c-a15c-cb87398f37ea aborted: Failed to allocate the network(s), not rescheduling. *Created *Dec. 29, 2020, 9:18 a.m.
*After this I can't ping the computer from the provider network interface.*
I reinstalled openstack so many times and also I tried the train and victoria version and have the same problem.
I attached log files of nova compute and neutron linux bridge from compute node and neutron server from controller node. thanks.
This looks like a bug in the neutron-linuxbridge-agent for me. What version of Neutron are you using? Did You try on master branch if the same issue occurs there? If yes, please open bug in the launchpad for that [1]. [1] https://bugs.launchpad.net/neutron/+filebug -- Slawek Kaplonski Principal Software Engineer Red Hat
