Best practice for multiple guests with public access

[kbrault]

Hello everyone,

It looks like there may be more than one method to have multiple guests have public IP's to the same external network (Multiple guests connected to one physical NIC. Guest VM's A, B and C would all be accessible from clients on the physical network through eth0).

1. Configure multiple virtual bridges to one physical NIC (vmbr0 --> eth0, vmbr1 --> eth0, etc) and configure each guest to connect to its own virtual NIC.
2. Configure every guest to connect to the same virtual NIC that is bridged to the physical NIC (vmbr0 --> eth0).
3. Other methods?

Is there a preferred practice and why?

Thanks,

Kevin

1. What exactly do you try to achieve with this approach?

Hi,
you can add an device only to one bridge...
But if this work, you can also use only vmbr0 because vmbr1 is the same... an bridge is like an network-hub.

Multiple guests connected to one physical NIC. For example guest VM's A, B and C would all be accessible from clients on the physical network through eth0.

Why not just connect said clients to the same bridge?
