All;
We're using OpenStack Victoria, with OVS networking (no OVN). I'm having some problems with a VLAN provider network that I added to my OpenStack. I have other VLAN provider networks, that I based this one off of.
Instances are getting the tap interfaces, but these interfaces are not getting IP addresses, and when a static IP is given, they can't ping either the DHCP address or the gateway address.
Can instances with static IPs ping each other or it also don't works?
I have checked the switch configuration, to verify the VLAN is bound appropriately. I rebooted the whole cluster to ensure the configuration change applied.
Here's a snip our plugin.ini [ml2_type_vlan] network_vlan_ranges = provider_core:55:55,provider_core:64:64,...
64 works, 55, doesn't.
I'm not seeing anything concerning in /var/log/openvswitch/ovs-vswitchd.log
I'm sure it's something dumb, but I'm not seeing it.
Please check also configuration of the OVS agent on the compute nodes where instances are configured and on the servers where DHCP agent's are running.
Any suggestions for what else to look at?
You should also check with tcpdump where packets are actually dropped. You can start checking on the physical interface in the host if there are packets with vlan_id 55 (the one which don't works). If packets are going out from compute node, You can check on Your switches and move to the next server. If packets are not on that physical interface, You should look in the Openflow rules configuration in the openvswitch on the compute node.
