Bug Description

I have deployed Openstack Victoria from kolla-ansible tool and Openvswich OVN for networking. neutron-ovn-db-sync tool generate OVN DB error when any subnet (disable dhcp) has allocated all available IP address. Because neutron-ovn-db-sync tool trying recreate port "network:distributed".

The problem occured when we have 1 subnet /30 and all port was allocated --> sync error with above message.
We workaround, remove 1 port in that subnet and Sync OK.

Hello:

I think there is a problem in the "_sync_metadata_ports" method, in [1]. If the subnet has DHCP disabled, the metadata port should not receive an IP address from this subnet. When a subnet without DHCP is created, the metadata port (already there because is created when the network is), does not receive any IP address.

We should make this check at this point too: if the subnet has "dhcp_enbled" to False, then we should update the port IPs but deleting, if exist, any IP address on this subnet (just the opposite of what is happening now).

Regards.

Fix "_sync_metadata_ports" with no DHCP subnets

    When a subnet does not have DHCP configured, the metadata port does
    not have an IP address on this CIDR. The method
    "OvnNbSynchronizer.sync_networks_ports_and_dhcp_opts", was always
    setting an IP address for the metadata ports, regardless of the subnet
    configuration (with or without DHCP).

The method "_sync_metadata_ports", in charge of synchronizing the
metadata ports, now filters the subnets by the parameter "enable_dhcp".

In case of having a subnet with DHCP enabled, if the metadata port is
missing the subnet IP addresses, the method adds them.

In case of having a subnet without DHCP enabled, if the metadata port
has an IP address on the subnet, the method removes it.

Fix "_sync_metadata_ports" with no DHCP subnets

The method "_sync_metadata_ports", in charge of synchronizing the
metadata ports, now filters the subnets by the parameter "enable_dhcp".

In case of having a subnet with DHCP enabled, if the metadata port is
missing the subnet IP addresses, the method adds them.

In case of having a subnet without DHCP enabled, if the metadata port
has an IP address on the subnet, the method removes it.
