2019-11-25 09:18:43 -0500 asked a question getting "MessagingTimeout: Timed out waiting for a reply to message ID ' while creating new instance in new rocky installation

We created new openstack cluster with kolla-ansible rocky release. I am able to create new networks, images. but we are getting message timeout while creating instance. I even tried with single node to eliminate any network issues and still getting same issue.

2015-05-13 12:30:10 -0500 asked a question neutron connectivity between private networks

I am trying to setup neutron network using vlan as follows.

Admin project: net1 - shared (used host route to go to net2) router1 - connected to external network and gateway of net1 vm1 - connected to net1

user_poeject1: net2 - private router2 - connected to gateway of net2 and second IP on net1 vm2 - connected to net2

I can ping all the IPs in net2 from vm1.

but from vm2, I can ping only vm1 IP, not the gateway of net1 or external network IPs.

can you please let me know what is missing in this setup. why can't I go to external network from net2 via router2 -> router1 -> external network?

We created one big shared network and want to use different rage IPs from this network in different projects. we are using neutron with vlan.
