[ovs-discuss] VLAN unable to ping

Well this is just plain bonkers now! I have removed the VLANs completely, rebooted the machine, and I still cannot ping the guests; yet they can ping each other:
ovs-vsctl show
76d53621-7bf2-4af2-b24c-181a016317d7
Bridge "ovsbr0"
Port "ovsbr0"
Interface "ovsbr0"
type: internal
Port "vnet1"
Interface "vnet1"
Port "eth0"
Interface "eth0"
Port "vnet0"
Interface "vnet0"
ovs_version: "1.10.2"
have I done something wrong with my physical network configuration. Am running Mint and have set the following:
auto eth0
iface eth0 inet static
address 0.0.0.0
auto ovsbr0
iface ovsbr0 inet static
address 192.168.1.52
network 192.168.1.0
netmask 255.255.255.0
broadcast 192.168.1.255
gateway 192.168.1.1
bridge_ports eth0
bridge_stp off
dns-nameservers 8.8.8.8
Any ideas please ?

This is sending me crazy. I thought if the bridge did not have any trunks assigned then everything would be untagged and passed though. I have tried adding trunk 10 (server network) to ovsbr0 and that has made no difference. Here is the current show:
ovs-vsctl show
76d53621-7bf2-4af2-b24c-181a016317d7
Bridge "ovsbr0"
Port "ovsbr0"
Interface "ovsbr0"
type: internal
Port "eth0"
Interface "eth0"
Port "vnet3"
trunks: [20]
Interface "vnet3"
Port "vnet0"
trunks: [0, 10]
Interface "vnet0"
Port "vnet2"
trunks: [0, 10]
Interface "vnet2"
Port "vnet1"
trunks: [20]
Interface "vnet1"
ovs_version: "1.10.2"
Any help would be gratefully appreciated.

Still cannot get this to work :( ping between the guests works absolutely fine on both VLANs, but no connectivity to the outside would or neither the host being able to ping the guests.

Did you configure the guest to use VLAN tag 2? I didn't see any
configuration for that in your "ifconfig" output.

getting a little further with this now. The guests are both able to ping each other on their 192.168.1.X address as-well as the SAN 10.0.0.X one. What they are unable to do is reach the outside world even though the default GW of 192.168.1.1 has been set. The host is also unable to ping the guests 192.168.1.X addresses even though it itself has a an address within the same range. Here is what I see:
uxbod-office sbin # ovs-vsctl show
76d53621-7bf2-4af2-b24c-181a016317d7
Bridge "ovsbr0"
Port "vnet3"
trunks: [20]
Interface "vnet3"
Port "vnet2"
trunks: [0, 10]
Interface "vnet2"
Port "ovsbr0"
Interface "ovsbr0"
type: internal
Port "eth0"
Interface "eth0"
Port "vnet1"
trunks: [20]
Interface "vnet1"
Port "vnet0"
trunks: [0, 10]
Interface "vnet0"
ovs_version: "1.10.2"
vnet0 = 192.168.1.56
vnet1 = 10.0.0.10
vnet2 = 192.168.1.90
vnet3 = 10.0.0.20
the physical nic and the bridge have no trunks or tags applied so I thought that they would pass all traffic to the guests:
uxbod-office sbin # ovs-vsctl list port ovsbr0
