Problem:
When the OVSPort is a vlan interface there is a sequencing issue when we try
to bring up the OVSBridge.
Consider the following configuration in /etc/network/interfaces
allow-ovs br-foo
iface br-foo inet static
address 1.1.1.1
netmask 255.255.255.0
ovs_type OVSBridge
ovs_ports eth1.2052
# Interface eth1.2052
allow-br-foo eth1.2052
iface eth1.2052 inet manual
ovs_type OVSPort
ovs_bridge br-foo
bridge_name br-foo
If we run 'service openvswitch start' then we'd get the following errors.
2015-10-08T00:05:45.279Z|00019|bridge|WARN|could not open network device
eth1.2052 (No such device)
Reason:
Due to the current sequence the script /etc/network/if-pre-up.d/openvswitch
with IF_OVS_TYPE=OVSPort is run prior to the script
/etc/network.if-pre-up.d/vlan which brings up the vlan interface eth1.2052.
saurabh@ubuntu-test:~$ run-parts --test /etc/network/if-pre-up.d/
/etc/network/if-pre-up.d//bridge
/etc/network/if-pre-up.d//ethtool
/etc/network/if-pre-up.d//openvswitch
/etc/network/if-pre-up.d//vlan
/etc/network/if-pre-up.d//wireless-tools
/etc/network/if-pre-up.d//wpasupplicant
Fix:
The fix is to order the openvswitch script to run after the other interface
scripts in /etc/network/if-pre-up.d/
