Issue with Multiple Nics/ IP aliases under VE 3.x

We've been using the following network configuration on our hardware nodes for several years without any issues under VE 2.2 and 2.3. We've just started building some new nodes with VE 3.x and have run into problems. Essentially the aliased interfaces are created but do not have any associated IP addresses. Manually creating interfaces and ip's work correctly as it always has on ipv4. I'm looking for answers as to why the old configuration no longer works and how to reestablish it under VE 3.x.

Working 2.2/2.3 network config:

Code: 
# more /etc/network/interfaces 
auto lo
iface lo inet loopback

auto vmbr0
iface vmbr0 inet static
        address xxx.yyy.zzz.218
        netmask 255.255.255.224
        gateway xxx.yyy.zzz.193
        broadcast xxx.yyy.zzz.223

Changing the IP address and deploying on a VE 3.x node results in the following:

My apologies. I moved it since the original was in the wrong category. This issue pertains to VE 3.x NOT VE 1.x. If it were possible to delete or recategorize the first I would have.
 
Resolved this myself. It appears the bridge control features are very different now.

Changing;

Code: 
auto vmbr0:0
iface vmbr0:0 inet static
        address 192.168.0.218
        netmask 255.255.255.0
        broadcast 192.168.0.255
        network 192.168.0.0
        bridge_ports eth0:0
        bridge_stp off
        bridge_fd 0

To:

auto vmbr0:0
iface vmbr0:0 inet static
        address 192.168.0.218
        netmask 255.255.255.0
        broadcast 192.168.0.255

Resolved all issues with the networking and allowed our config to work properly.
